  • The total size of memory-mapped files in Windows was limited because the memory manager allocated the Prototype Page Table entries PPTEs for the entire file, even if an application created mapped views to only parts of the file. A benefit of this, for example, is in case of making backups of large files on low memory systems. The paged pool limit of MB has been lifted from the Memory Manager in Windows XP, with unmapped views dynamically reusable by the memory manager depending on pool usage.

    Memory pages in working sets are trimmed more efficiently for multiprocessor systems depending on how recently they were accessed. The dispatcher lock contention has been reduced and the Page Frame Number PFN lock has been optimized for increased parallelism and granularity.

    Apr 17,  · Firewall App Blocker is a free and portable firewall utility which can quickly block any Windows applications from accessing the Internet. The layout of Firewall App Blocker is simple to use and by taking advantage of the built-in Windows Firewall, you're very unlikely from noticing any increase in CPU or memory usage. 8/10 ( votes) - Download Windows XP SP2 Free. With Windows XP SP2 you will be able to install the second pack of updates necessary for that operating system. Download Windows XP SP2 for free to your PC. Windows XP is one of the users' favorite operating systems developed by Microsoft. It was. Windows Movie Maker 2 was a free download released in , later incorporated in Windows XP SP2. Windows Movie Maker 2 introduced numerous new transitions, effects, titles and credits, a task pane, resizable preview window with dimensions, improved capture and export options, an AutoMovie feature, saving the final video back to tape and custom.

    Windows XP uses push locks on the event synchronization object if there is no contention as they support shared and exclusive acquisition. Push locks protect handle table entries in the Executiveand in the Object Manager to protect data structures and security descriptors and Memory Manager to protect AWE -related locks. The kernel page write protection limit in Windows XP is enabled on systems up to MB of RAM beyond which large pages are enabled for increased address translation performance.

    Windows XP introduces the CreateMemoryResourceNotification function which can notify user mode processes of high or low memory availability so applications can allocate more memory or free up memory as necessary. In Windows XP, the registry is reimplemented outside of the paged pool; the registry hives are memory mapped by the Cache Manager into the system cache, eliminating the registry size limit. The registry size is now limited only for the available disk space.

    The System hive still has a maximum size, but it has been raised from 12 MB to MB, eliminating the issue previous Windows versions faced [38] of being unable to windows because of a large or fragmented System hive. The Configuration Manager has been updated to frree the registry's memory footprint and lock contentionreduce fragmentation and thus page faults when accessing the registry, and improved algorithms to speed up registry query processing.

    An in-memory security cache eliminates redundant security descriptors. Windows XP supports cross user session debugging, attaching the debugger to a non-crashing user-mode program, dumping the process memory space using the dump command, and then detaching the debugger without terminating it. Sownload can be done over a FireWire port and on a local system.

    The debug heap can be disabled and the standard heap be used when debugging. Heap leak detection can be enabled when processes free and a debugger extension can be used to investigate leaks. Also introduced is a new heap performance-monitoring counter. Windows XP introduces a new low fragmentation heap policy disabled by default which allocates memory in distinct sizes for blocks less than 16KB to firewlal heap fragmentation.

    In low memory conditions, "must succeed" calls are denied, causing a slowdown but preventing a bug check. NTFS 3. There are new APIs to preserve original short file names, to retrieve a list of mount points drive letters and mounted folder paths for the specified volume, and to enable applications to create very large files quickly by setting the valid data length on files without force-writing data with zeroes up to the VDL SetFileValidData function. For instance, this function can be used to quickly create a fixed size virtual winxows hard disk.

    Legacy file system filter drivers attached to the file system stack directly and didn't have the aforementioned flexibility. Upon system boot or the launch of an application, any data and code in the trace that is not already in memory is prefetched from the disk. The previous prefetching results firewall which scenario benefited more and what should be prefetched at the next boot or launch.

    The prefetcher also uses download same algorithms to reduce application startup times. To reduce disk seeking even further, the Disk Defragmenter is called in at idle time to optimize the layout of downpoad specific files and metadata in a contiguous area.

    Boot and resume operations can be traced and analyzed using Bootvis. Windows XP includes a Fast Logon Optimization feature that performs logon asynchronously without waiting for the network to be fully initialized if roaming user profiles are not set up. Group Policy is applied in the background, and startup or logon scripts execute asynchronously by default.

    Windows XP reconciles local and roaming user profiles using a copy of the contents of the registry. The user is no longer made to wait as in Windows until the profile is unloaded. Windows XP saves locked registry hives with open keys after 60 seconds so that roaming profile changes can be saved for to the server.

    The problem left is that the computer cannot recover the memory the profile uses until it can be unloaded. To make sure the user profiles are completely reconciled correctly during logoff, Microsoft has released the User Profile Hive Cleanup service for Windows Firewall, which they later included in Windows Vista.

    Windows XP offers enhancements for usability, resilience against corruption and performance of roaming user profiles. To accommodate the scenario where an older profile would windows a newer server profile due to Windows XP's Fast Logon feature, Windows XP ensures in such a situation that the user registry hive is copied from the server to the local profile. Deletion of profiles marked for deletion at the next logoff does not fail for locked profiles.

    For workgroup computers, Windows Free no download deletes the profiles of users belonging to the Guests group. Windows XP includes some changes to the behavior of Offline Files. Shared folders from DFS namespaces can be made available offline. Administratively assigned offline files can also be prevented from being cached for non-primary users. Beginning with Windows XP, folders redirected to the network are automatically made available offline using Offline Filesalthough this can optionally be disabled through Group Policy.

    For older Windows NT 4. In Windows XP, System Restore is configurable per volume and the data stores are also stored per volume.

    Features new to Windows XP - Wikipedia

    A Disk Cleanup handler allows deleting all but the most recent Restore Point. System Restore supports Group Policy. Automated System Recovery is a feature that provides the ability to save and restore Windows and installed applications, the system stateand critical boot and system files from a special backup instead of a plain reinstall. A common issue in previous versions of Windows was that users frequently suffered from DLL hellwhere more download one version of the same dynamically linked library DLL was installed on the computer.

    As software relies on DLLs, using the wrong version could result in non-functional applications, or worse. These operating systems allowed loading a free version of the DLL if it was placed in the application's folder by the developer, instead of the system directory and must be registered properly with the system. The technology keeps multiple digitally signed versions of a shared DLL in a centralized WinSxS folder and runs them on demand to the appropriate application keeping applications isolated from for other and not using common dependencies.

    Manifests and windows assembly version number are used by the OS loader to determine the correct binding of assembly versions to applications instead of globally registering these components. Instead, the metadata and CLSIDs of the classes implemented in the component are declared in an assembly manifest described using XMLstored either as a resource in the executable or as a separate file installed with the component.

    During application loading, the Windows loader searches for the manifest. Only if the lookup fails is the registry scanned. Windows Error Reporting collects and offers to send post-error debug information a memory dump using the internet to the developer of an application that crashes or stops responding on a user's desktop. No data is sent without the user's consent. When a dump or other error signature information reaches the Microsoft server, it is analyzed and a solution is sent back to the user firewall one is available.

    Windows Error Reporting runs as a Windows service and can optionally be entirely disabled. Software and hardware manufacturers may access their error reports using Microsoft's Winqual program. This allows distributing solutions as well as collecting extra information from customers such as reproducing the steps they took before the crash and providing them with support links. On old versions of Windows, when users upgrade a device driver, there is a chance the new driver is less stable, efficient or functional than the original.

    Reinstalling the old driver can be a major hassle and to avoid this quandary, Windows XP keeps a copy of an old driver when a new version is installed. If the new driver has problems, the user can return to the previous version. This feature does not work with printer drivers.

    As Windows XP merged the consumer and enterprise versions of Windows, it needed to support applications developed for the popular and consumer-oriented Windows 9x platform on the Windows NT kernel. Microsoft addressed this by improving compatibility with application-specific tweaks and shims and by providing tools such as the Application Compatibility Toolkit AppCompat or ACT [62] to allow users to apply and automate these tweaks and shims on their own applications.

    Windows Movie Maker 2 introduced numerous new transitions, effects, titles and credits, a task pane, resizable preview window with dimensions, improved capture and export options, an AutoMovie feature, saving the final video back to tape and custom WMV export profiles. Windows XP includes advances in Broadcast Driver Architecture for receiving and capturing analog and digital TV broadcasts complete with signal demodulation, tuning, software de-multiplexing, electronic program guide store, IP data broadcasting etc.

    VMR-7 can mix multiple streams and graphics with alpha blending, allowing applications to draw text such as closed captions and graphics such as channel logos or UI buttons over the video without flickering, and support compositing to implement custom effects and transitions.

    VMR-7 features a "windowless mode" for applications to easily host video firewxll within any window and a "renderless playback mode" for applications to access the composited image before it is rendered. DirectShow 8 includes AVStreama multimedia class driver for video-only and audio-video kernel streaming. For mass storage devices, Windows XP introduces hardware descriptors to distinguish between various storage types so that the operating system can set an appropriate default write caching policy.

    Device Manager download a configuration setting whether to optimize devices for quick removal or for performance. The Scanner and Camera Downkoad based on Windows Image Acquisition and free common dialogs for WIA devices have been improved in Windows XP to show the media information and metadata, rotate images as necessary, categorize them into subfolders, capture images and video in case of a still or video camera, crop and scan images to a single or multi-page TIFF in case of a scanner.

    The Picture Transfer Protocol PTP implementation has been updated to support all mandatory and optional commands in the PTP standard, and object tree support which allows secondary files associated with a parent file to be grouped and transferred concurrently. Windows XP includes technology from Roxio which allows users to directly burn files to a compact disc through Windows Explorer.

    Previously, end users had to install CD burning firewzll. Windows XP's CD burning support does not do disk-to-disk copying or disk imagesalthough the API can be used programmatically to do these tasks. Audio CDs are burnt using track-at-once mode. As mentioned in the above sectionWindows XP includes windows support for FireWire cameras and audio video devices.

    Direct memory access over the bus from the host to the target allows kernel debugging over FireWire. WSF has been introduced besides. VBS and. JS which can store fitewall for XML node in the same file, extra information firewall script code, such as digital signature blocks, runtime directives or instructions to import external code. The WshShell object now supports a 'CurrentDirectory' read-write method. Scripts can now be digitally signed as well as verified programmatically using the Scripting.

    Signer object in a script itself, provided a valid certificate is present on the system. WSH can thus decide whether or not to execute the script after verification. The signature block is stored in a commented section in the script file download backward compatibility aindows older WSH versions. By using Software Restriction Policies supported in Windows XP and later, a system may also be configured to execute only those scripts which have been digitally signed, thus preventing the execution of untrusted scripts.

    Local scripts can also run on a remote machine with the new WScript. The remote script can be monitored by using the Status property. WSH firweall. In earlier versions of Windows Script, to use arguments, one had to access the WshArguments collection object which could not be created externally and required that the person running the script know the download of the arguments, and their syntax and values. Named arguments are grouped windows the Named collection object and have the usual methods like Item, Count, Length as well as an Exists method.

    Password COM automation object, implemented in the scriptpw. It is built on Terminal Services technology RDPand is similar to "Remote Assistance", but allows remote users to access local resources such as printers. There are several resources that users can redirect from the remote server machine to the local client, depending upon the capabilities of the client software used. For instance, "File System Redirection" allows users to use their local files on a remote desktop within the terminal session, while "Printer Redirection" allows users to use their local printer within the terminal session as they would with a locally firewalll network shared printer.

    The firewall can also fireewall shared between the remote computer and the local computer. Remote Assistance allows sending invitations to the support person by email, Windows Firewall or saving the invitation as a file. The computer can be controlled by both, the support person connecting remotely as well as the one sending the invitation.

    Chat, ffirewall conversations and file transfer cp available. Windows XP introduces Fast User Switching [] and wincows more end user friendly Welcome Screen with a user account picture which replaces the Classic logon prompt. Fast user switching allows another user to rirewall in and use the system without having to log out the previous user and quit his or her applications.

    Previously on both Windows Me and Windows only one user at a time could be logged in except through Terminal Serviceswhich was a serious drawback to multi-user activity. Fast User Switching, like Terminal Services, requires more system resources than having only a single user logged in at a time and although more than one user can be logged in, only one user can be actively using their account at a time. Winsows feature is free available when the Welcome Screen is turned off, such as when joined to a Windows Server Ffree or with Novell Client installed.

    Windows Installer 2. Windows Disk Defragmenter was updated to alleviate several restrictions. The defragmenter supports For volumes with cluster sizes larger than 4 kilobytes. A command-line tool, defrag. Users who are members of the Windows Users group can schedule defragmentation. It has been updated to display process names longer than 15 characters in length on the Processes tab, which used to be truncated in Windowe The Delete key can also be used dowhload terminate processes on the Processes for. A new Networking tab shows statistics relating to each of the network adapters present in the computer.

    By default the adapter name, percentage of network utilization, link speed and state of the network adapter are shown, along with a chart of recent activity. More options can be shown by choosing Select columns The Users tab shows all users that ror have a session on the computer. On free computers there may be several users connected to the computer using Terminal Services. There may also be multiple users logged onto the computer at one time using Fast User Switching.

    Users can be disconnected or logged off dlwnload this tab. Holding down Ctrl while clicking New Task opens a command prompt. User -type certificates can be auto-enrolled and renewed. Root CA certificates now also auto-update via Microsoft Update. Windows XP can enroll version 2 certificate templates which have many configurable attributes. There are also numerous improvements to certificate status checking, chain building and revocation checking, path validation and discovery.

    Windows XP includes several Encrypting File System improvements [] The most downliad improvement is that multiple user accounts can share access to encrypted files on a file-by-file basis. A Details button in the Advanced file attributes dialog in the file's properties allows adding or removing additional users who can access the EFS-encrypted file, dwonload viewing the certificate thumbprint and the Data Recovery Agent account.

    EFS certificates are autoenrolled in cree CA and there is support for revocation checking on certificates used when sharing encrypted files. Windowss Windowsthere is no default local Data Recovery Agent and no requirement to have one, although a self-signed certificate for the recovery agent can be generated using cipher. Windows XP can also encrypt files on a remote server with NTFS if the server is trusted for delegation in Active Directory and the user's certificate and private key are loaded in the local profile on the server.

    If a roaming user profile is used, it will be copied locally.

    The command line utilities ciphercopy and xcopy have been updated in Windows XP. For faster cache validation, for time for how long the user session key and certificate chain are cached can be adjusted. This disk can be used to reset the password using the Password Reset Wizard from the logon screen. The user's RSA private key is backed up using an offline public key download matching private key is stored in one of two places: the password reset disk if the computer is not a member of a domain or in Active Directory if it is a member of a domain.

    An attacker who can authenticate to Windows XP as LocalSystem still does not firewall access to a decryption key stored on the PC's hard drive. Free the user changes the password back to the original password, EFS encrypted files can be recovered. Windows XP prompts for credentials upon authentication errors and allows saving those that use Integrated Windows Authentication to a secure roaming keyring store protected by the Data Protection API.

    Saved credentials can be managed from the Stored User Names and Passwords item in the User accounts control panel. If a certificate authority is present, then users can a select an X. When that same resource is accessed again, the saved credentials will be used. Windows XP introduces Software Restriction Policies and the Safer API [] [] By use of Software Restriction Policies, a system may be configured to execute or install only those applications and scripts which have been digitally signed or have a certain trust level, thus windows the execution of untrusted programs and scripts.

    Administrators can define a default rule using the Local Security Policy snap-in, and exceptions to that rule. The layout of Firewall App Blocker is simple to use and by taking advantage of the built-in Windows Firewall, you're very unlikely from noticing any increase in CPU or memory usage. Using this firewall application is as easy as dragging and dropping application executables into the main window.

    You can also right-click items in the listings of Firewall App Blocker to delete, rename, block, unblock, etc. The options of this application aren't many, but you can quickly use the options menu to reset firewall settings or change firewall settings.

    Windows XP SP2 is the second of these updates, a collection of security patches, error fixes and improvements to its performance and stability. The innovations that the second Service Pack for Windows XP includes, improve it greatly and have a lot to do with the loyalty that most users of this operating system have towards it. Among them, one of the most important new things that it includes is the default firewall for the operating systemthat controls the inbound and outbound connections between frwe computer and the Internet.

    You can also notice the improvement to the performance, to such an extent that some applications will not work properly if you haven't installed Windows XP SP2 on the computer. Wimdows essential and even compulsory update downlosd Windows XP for those who still enjoy this version of the Microsoft operating system.

      Quickly block any applications from accessing the Internet with firewall. Firewall App Blocker is a free and portable firewall utility which can quickly block any Windows applications from accessing the Internet.

    2. Amy Belgarde:

      Windows XP is one of the users' favorite operating systems developed by Microsoft. It was launched in as the successor of Windows and the professional Windows NT, and there are still many people that prefer it to Windows Vista. The main reasons for this are its good general performance and its limited use of computer resources.

    3. Maria Broussard:

      As the next version of Windows NT after Windows , as well as the successor to Windows Me , Windows XP introduced many new features but it also removed some others. Use of these features is apparent in Windows XP's user interface transparent desktop icon labels, drop shadows for icon labels on the desktop, shadows under menus, translucent blue selection rectangle in Windows Explorer , sliding task panes and taskbar buttons , and several of its applications such as Microsoft Paint , Windows Picture and Fax Viewer , Photo Printing Wizard , My Pictures Slideshow screensaver, and their presence in the basic graphics layer greatly simplifies implementations of vector-graphics systems such as Flash or SVG.
