.NET Framework是用于Windows的新托管代码编程模型。它强大功能与新技术结合起来，用于构建具有视觉上引人注目的用户体验的 应用程序 ，实现跨技术边界的无缝通信，并且能支持各种业务流程。 别跟哥说你用不上这个软件，这个软件对于实用较大开发的软件，比如说我们的常用的mapgis二次开发，比如说我们用的卡本，cad等等特别是一些大型游戏如果没有这个基本上就安装都安装不了，让你超级郁闷，而这个软件却不是那么的稳定。 XP的系统，装好后常出现下面这种情况， .NET framework2.0无法卸载,无法安装,无法修复 在2003中也常出现，但是我们在系统中找不到卸载.net2.0 3.0的删除程序，手动删除又怕注册表中没删除而造成更大的错误！同时还有一件更郁闷的事情就是常用的强制卸载软件根本不能卸载它，所以在这里我就推荐这样一个手写的小软件，很好用的 下面是转载作者的说明 ---------------------------------------------------华丽的分界线-------------------------------------------------------- 。NET Framework Cleanup Tool User's Guide Introduction This .NET Framework cleanup tool is designed to automatically perform a set of steps to remove selected versions of the .NET Framework from a computer. It will remove files, directories, registry keys and values and Windows Installer product registration information for the .NET Framework. The tool is intended primarily to return your system to a known (relatively clean) state in case you are encountering .NET Framework installation, uninstallation, repair or patching errors so that you can try to install again. There are a couple of very important caveats that you should review before using this tool to remove any version of the .NET Framework from your system: This tool is designed as a last resort for cases where install, uninstall, repair or patch installation did not succeed for unusual reasons. It is not a substitute for the standard uninstall procedure. You should try the steps listed in this blog post before using this cleanup tool. This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework. If you run the cleanup tool, you will need to perform a repair/re-install for all other versions of the .NET Framework that are on your computer or they will not work correctly afterwards. Download location The .NET Framework cleanup tool is available for download at the following locations: 本网站下载地址： dotnetfx_cleanup_tool.zip http://u.115.com/file/f263f0bc14 （外站下载链接） The .zip file that contains the tool also contains a file named history.txt that lists when the most recent version of the tool was published and what changes have been made to the tool over time. Supported products The .NET Framework cleanup tool supports removing the following products: .NET Framework - All Versions .NET Framework - All Versions (Tablet PC and Media Center) .NET Framework - All Versions (Windows Server 2003) .NET Framework - All Versions (Windows Vista and Windows Server 2008) .NET Framework 1.0 .NET Framework 1.1 .NET Framework 2.0 .NET Framework 3.0 .NET Framework 3.5 .NET Framework 4 Not all of the above products will appear in the UI for the .NET Framework cleanup tool on every operating system. The cleanup tool contains logic so that if it is run on an OS version that includes the .NET Framework as an OS component, it will not offer the option to clean it up. This means that running the cleanup tool on Windows XP Media Center Edition or Tablet PC Edition will not offer the option to clean up the .NET Framework 1.0, running it on Windows Server 2003 will not offer the option to clean up the .NET Framework 1.1 and running it on Windows Vista or Windows Server 2008 will not offer the option to clean up the .NET Framework 2.0 or the .NET Framework 3.0. When choosing to remove any of the above versions of the .NET Framework, the cleanup tool will also remove any associated hotfixes and service packs. You do not need to run any separate steps to remove the service pack(s) for a version of the .NET Framework. Silentinstallation mode The .NET Framework cleanup tool supports running in silent mode. In this mode, the tool will run without showing any UI, and the user must pass in a version of the .NET Framework to remove as a command line parameter. To run the cleanup tool in silent mode , you need to download the cleanup tool, extract the file cleanup_tool.exe from the zip file, and then run it using syntax like the following: cleanup_tool.exe /q:a /c:"cleanup.exe /p name of product to remove" The value that you pass with the /p switch to replace name of product to remove in this example must exactly match one of the products listed in the Supported products section above. For example, if you would like to run the cleanup tool in silent mode and remove the .NET Framework 1.1, you would use a command line like the following: cleanup_tool.exe /q:a /c:"cleanup.exe /p .NET Framework 1.1" One important note – as indicated above, the cleanup tool will not allow you to remove a version of the .NET Framework that is installed as part of the OS it is running on. That means that even if you try this example command line on Windows Server 2003, the tool will exit with a failure return code and not allow you to remove the .NET Framework 1.1 because it is a part of that OS. Similarly, you cannot use the cleanup tool to remove the .NET Framework 1.0 from Windows XP Media Center Edition or Windows XP Tablet PC Edition or remove the .NET Framework 2.0 or 3.0 from Windows Vista or Windows Server 2008. In addition, if you run the cleanup tool on an OS that has any edition of the .NET Framework installed as a part of the OS, it will prevent you from using the .NET Framework - All Versions option because there is at least one version that it cannot remove. If you are planning to run the cleanup tool in silent mode, you need to make sure to detect what OS it is running on and not pass in a version of the .NET Framework with the /p switch that is a part of the OS or make sure that you know how to handle the failure exit code that you will get back from the cleanup tool in that type of scenario. Unattended installation mode The .NET Framework cleanup tool supports running in silent mode. In this mode, the tool will run and only show a progress dialog during removal, but will require no user interaction. Unattended mode requires the user to pass in a version of the .NET Framework to remove as a command line parameter. To run the cleanup tool in unattended mode , you need to download the cleanup tool, extract the file cleanup_tool.exe from the zip file, and then run it using syntax like the following: cleanup_tool.exe /q:a /c:"cleanup.exe /p name of product to remove /u" For example, if you would like to run the cleanup tool in unattended mode and remove the .NET Framework 1.1, you would use a command line like the following: cleanup_tool.exe /q:a /c:"cleanup.exe /p .NET Framework 1.1 /u" Exit codes The cleanup tool can returns the following exit codes: 0 - cleanup completed successfully for the specified product 3010 - cleanup completed successfully for the specified product and a reboot is required to complete the cleanup process 1 - cleanup tool requires administrative privileges on the machine 2 - the required file cleanup.ini was not found in the same path as cleanup.exe 3 - a product name was passed in that cannot be removed because it is a part of the OS on the system that the cleanup tool is running on 4 - a product name was passed in that does not exist in cleanup.ini 100 - cleanup was able to start but failed during the cleanup process 1602 - cleanup was cancelled Log files The cleanup tool creates the following log files: %temp%\cleanup_main.log - a log of all activity during each run of the cleanup tool; this is a superset of the logs listed below as well as some additional information %temp%\cleanup_actions.log - a log of actions taken during removal of each product; it will list files that it finds and removes, product codes it tries to remove, registry entries it tries to remove, etc. %temp%\cleanup_errors.log - a log of errors and warnings encountered during each run of the cleanup tool
【计算机技巧】修复explorer被木马病毒破坏的系统 现象：前几天，我的计算机能够启动，但是进入桌面后，桌面所有的图标和工具栏不能显示，也不能运行windows资源管理器，瑞星杀毒软件被关闭。按Ctrl+Alt+Delete进入任务管理器，发现系统进程中出现两个explorer，一个为小写，另一个第一个字母大写。同时进程中出现aa+随机7位数字务的奇怪进程，可以被结束，但是很快又出现。我的操作系统为 windows xp SP2。相信各位同仁计算机中保存了大量的资料，如果因此可能遭受重大损失。下面就是如何处理，供参考，以避免损失。 处理：按Ctrl+Alt+Delete进入任务管理器，在新建任务中输入CMD，进入dos界面；在DOS下输入命令CD C:\WINDOWS；进入windows目录后，输入命令DEL aa*.EXE，删除所有木马生成的AA+随机数字的文件。退出DOS。 按Ctrl+Alt+Delete进入任务管理器，在新建任务中输入iexplorer，在360网站找到360顽固木马专杀大全软件并下载。下载后，按Ctrl+Alt+Delete进入任务管理器，在新建任务中输入下载文件名，该软件会自动解压，解压后在任务管理器中运行SuperKiller，360顽固木马专杀工具会对木马进行查杀，并修复explorer。重启计算机，基本恢复，但是杀毒软件需要修复或重新安装。
