在新安装的 Windows 7 PC 上安装更多程序和驱动程序之前，请确保已启用系统^(System) 保护。^(Protection)系统^(System)保护是一项定期创建和保存有关计算机系统文件和注册表信息的功能。

系统^(System)保护还会保存您修改过的文件的先前版本。它将这些文件保存在还原点中，这些还原点是在重大系统事件（例如安装程序或设备驱动程序）之前创建的。默认情况下，安装Windows的驱动器会自动开启^(Windows)系统^(System)保护。只能为使用NTFS文件系统格式化的驱动器打开系统保护。^(System)

要检查您是否打开了保护，请转到“控制面板^{(Control Panel)}”，单击“系统^{(System )}”，然后选择“系统保护”^{(System Protection)}。

将出现系统属性^{(System Properties)}对话框。单击系统保护^{( System Protection)}选项卡。查找标有系统^(System)的驱动器- 这是安装Windows 7的驱动器。此驱动器的保护默认情况下是打开的 - 如果没有，请单击它以将其打开。您可以根据需要开启其他非系统盘的系统保护。如果这样做，您可以恢复这些驱动器中文件的先前版本。

单击配置^{(Configure )}按钮以查看还原点使用的还原设置和最大空间。如果您的计算机上有大量空间，最好选择“还原系统设置和文件的先前版本”^{(Restore system settings and previous versions of files)}选项并设置“最大使用^{( Max Usage)} 百分比”，使其大小大于 5 GB。

如果要查看系统创建的还原点，请单击“系统^(System) 还原”^{(Restore )}按钮。

将出现还原点列表。如果您需要从可用的还原点之一进行还原，您将来可能会转到此列表。

系统还原^{(System Restore)}是一种在不影响您的个人文件（例如电子邮件、文档或照片）的情况下撤消对计算机的系统更改的方法。如果您安装的程序或驱动程序导致您的计算机发生意外更改并且卸载程序或驱动程序无法解决问题，则系统还原是最佳选择。^{(System Restore)}

如果您使用系统还原已经有一段时间了，但没有看到您创建的所有还原点，请查看我关于Windows 中缺少还原点^{(missing restore points in Windows)}的文章。如果您对系统还原有任何疑问，请在评论中发表。享受！

How to Enable System Restore in Windows 7

Before you install more programs and drivers on your newly installеd Windowѕ 7 PС, make sure уou have System Protection enabled. System protection is a feature that regularly creates and saves information about your computer’s system files and registry.

System protection also saves previous versions of files that you’ve modified. It saves these files in restore points, which are created just before significant system events, such as the installation of a program or device driver. By default System protection is automatically on for the drive that Windows is installed on. System protection can only be turned on for drives that are formatted using the NTFS file system.

To check if you have the protection turned on go to the Control Panel, click System then choose System Protection.

The System Properties dialog will appear. Click the System Protection tab.  Look for the drive marked with System – this is the drive where Windows 7 is installed.  The protection for this drive is on by default – if not, click it to turn it on.  You may turn on the system protection of other non-system disks if you like.  If you do this, you can restore previous versions of files inside those drives.

Click the Configure button to see the restore settings and maximum space used by the restore points. If you have a large amount of space on your computer, it’s a good idea to choose the Restore system settings and previous versions of files option and to set the Max Usage percentage so that it’s greater than 5 GB in size.

If you want to see the restore points created by your system, click the System Restore button.

The list of restore points will appear.  You may go to this list in the future if you need to restore from one of the available restore points.

System Restore is a way to undo system changes to your computer without affecting your personal files, such as email, documents, or photos. System Restore is the best choice if you installed a program or driver that caused an unexpected change to your computer and uninstalling the program or driver didn’t fix the problem.

If you’ve been using system restore for some time and you don’t see all the restore points you created, check out my articles on missing restore points in Windows. If you have any questions about system restore, post them in the comments. Enjoy!
