尝试使用System Restore 还原系统^{(System Restore)}时，该程序可能无法运行并抛出以下错误消息 -系统还原未成功完成。发生未指定的错误 0x80071a90^{(System Restore did not complete successfully. An unspecified error occurred 0x80071a90)}。如果你遇到这个问题，那么这篇文章可能会帮助你解决这个问题。

系统还原^{(System Restore)}未成功完成

系统还原^{(System Restore)}无法用还原点的原始副本替换文件。

系统还原^{(System Restore)}期间出现未指定的错误(0x80071a90)

系统还原^{(System Restore)}未成功完成，错误代码 0x80071a90^{(Error Code 0x80071a90)}

遇到上述问题，可能会打断你的流程，彻底毁掉你的工作。不过^{(Nevertheless)}，您可以通过遵循任何一种给定的方法来解决系统还原问题^{(fix System Restore problems)}。

1. 检查可用磁盘空间
2. 确保启用系统还原^{(System Restore)}
3. 检查服务状态
4. 重置存储库。
5. 暂时禁用安全软件
6. ^{(Run System Restore)}在干净启动状态下^{(Clean Boot State)}运行系统还原
7. 修复系统镜像
8. 检查事件日志。

请看下面的详细说明！

1]检查可用磁盘空间

您不能只是继续向驱动器添加内容并保持这种状态。应不时检查可用空间。当您启用系统还原时，同样的原则也适用。^{(System Restore)}当您收到“系统还原^{(System Restore)}未成功完成”错误消息时，检查您是否有足够的可用磁盘^(Disk)空间。如果没有，请使用磁盘清理工具清除垃圾文件^{(use Disk Cleanup Tool to clear out junk files)}。母鸡，继续这个过程。

2]确保启用系统还原^{(System Restore)}

验证所需驱动器上是否启用了系统还原^{(System Restore is enabled on the desired drive)}尤为重要。有时，您在不同的驱动器上尝试操作，因此无法完成。

3]检查服务的状态

在 Windows中检查服务的状态^{(check the status of services)}相当容易。只需输入Services.msc开始菜单搜索框^{(Start Menu Search Box)}，然后按 Enter^(Enter)。

现在，确保Volume Shadow Copy & Task Scheduler & Microsoft Software Shadow Copy Provider Service正在运行并设置为Automatic。

此外，如果系统还原服务^{(System Restore Service)}的状态^(Status)未启动，请启动它并将其设置为自动^(Automatic)。

4]修复系统映像

系统映像代表驱动器的精确副本。它允许您将计算机恢复到创建备份时的状态。如果由于损坏或某些未知原因而损坏，您可以运行 DISM 工具来修复损坏的 Windows 系统映像^{(run the DISM tool to repair a corrupted Windows System Image)}并删除错误消息。

5]重置存储库

如果您的Windows设备在读取Windows 管理界面^{(Windows Management Interface)}( WMI ) 存储库时遇到问题，您可能需要重置存储库作为故障排除步骤。为了这，

在没有网络的情况下启动^(Boot)进入安全模式^{(Safe Mode)}并以管理员身份打开命令提示符。

在命令提示符^{(Command Prompt)}窗口中，键入以下内容并按 Enter：

net stop winmgmt

确认后的操作将停止Windows Management Instrumentation 服务^{(Windows Management Instrumentation Service)}

接下来，转到C:\Windows\System32\wbem并将存储库文件夹重命名为repositoryold。

重新开始。

再次^(Again)以管理员身份打开命令提示符，键入以下内容，然后按 Enter^(Enter)：

net stop winmgmt

此后，键入以下内容并按Enter键。

winmgmt /resetRepository

现在，只需重新启动 PC 并检查是否可以手动创建系统还原点。^{(System Restore Point)}

6]在干净启动状态下^{(Clean Boot State)}创建系统还原点^{(Create System Restore Point)}

执行干净启动^{(Perform a Clean Boot)}，然后尝试创建系统还原点并查看是否有效。

7]暂时禁用安全软件^(Disable)

有时，您为保护系统及其文件而运行的安全软件会干扰系统还原^{(System Restore)}过程。因此，请禁用您已启用的防病毒或反恶意软件程序，然后再次尝试系统还原^{(System Restore)}。

8]检查事件日志

Windows会记录事件，尤其是与定期备份有关的事件。您可以使用此信息来查明原因并快速修复它。

输入搜索框^{(Search Box)}eventvwr.msc /s并按Enter打开事件查看^{(Event Viewer)}器^(Enter)。

在这里，双击应用程序^{(Applications)}和服务日志^{(Services Logs)}以查看您是否能够评估事件描述或问题的原因。

Hope it helps!

System Restore did not complete successfully, Error Code 0x80071a90

When trying to restore the system using Ѕystem Rеstore, the program may fail to work and throw up the following error message – System Restore did not complete successfully. An unspecified error occurred 0x80071a90. If you face this issue, then this post may help you fix the issue.

System Restore did not complete successfully

System Restore failed to replace the file with its original copy from the restore point.

An unspecified error occurred during System Restore (0x80071a90)

System Restore did not complete successfully, Error Code 0x80071a90

Encountering an issue such as the one mentioned above, can interrupt your flow, and ruin your work completely. Nevertheless, you can overcome it by following any one of the given methods to fix System Restore problems.

1. Check available Disk Space
2. Ensure that System Restore is enabled
3. Check the status of Services
4. Reset the Repository.
5. Disable security software temporarily
6. Run System Restore in Clean Boot State
7. Repair system image
8. Check Event Logs.

See the detailed description below!

1] Check available Disk Space

You can’t just keep adding stuff to a drive and leave it that way. It should be checked for the free space available from time to time. The same principle applies when you have System Restore enabled. Check if you have sufficient Disk space available when you get the ‘System Restore did not complete successfully’ error message. If not, use Disk Cleanup Tool to clear out junk files. hen, proceed with the process.

2] Ensure that System Restore is enabled

It is particularly important to verify that System Restore is enabled on the desired drive. Sometimes, you try the operation on a different drive, and therefore it fails to complete.

3] Check the status of Services

It’s fairly easy to check the status of services in Windows. Simply type Services.msc in Start Menu Search Box and hit Enter.

Now, make sure that the Volume Shadow Copy & Task Scheduler & Microsoft Software Shadow Copy Provider Service is Running and set on Automatic.

Also, if the Status of System Restore Service is Not Started, Start it and set the same to Automatic.

4] Repair system image

A system image represents an exact copy of a drive. It allows you to return your computer to the state that existed at the time when the backup was created. If it gets damaged due to corruption or some unknown reason, you can run the DISM tool to repair a corrupted Windows System Image and remove the error message.

5] Reset the repository

If your Windows device is experiencing trouble reading from the Windows Management Interface (WMI) repository, you may need to reset the repository as a troubleshooting step. For this,

Boot into Safe Mode without networking and open a command prompt as administrator.

In the Command Prompt window, type the following and hit Enter:

net stop winmgmt

The action when confirmed will stop the Windows Management Instrumentation Service

Next, go to C:\Windows\System32\wbem and rename the repository folder to repositoryold.

Restart.

Again open a command prompt as administrator, type the following, and hit Enter:

net stop winmgmt

thereafter, type the following and press Enter key.

winmgmt /resetRepository

Now, simply restart your PC and check if you can create a System Restore Point manually.

6] Create System Restore Point in Clean Boot State

Perform a Clean Boot and then try to create a system restore point and see if that works.

7] Disable security software temporarily

Sometimes, the security software you run to protect your system and its files interferes with the System Restore process. As such, disable the anti-virus or anti-malware program you have enabled and try the System Restore again.

8] Check Event Logs

Windows logs events, especially ones pertaining to backups on a regular basis. You can use this information to pinpoint the cause and fix it quickly.

Type eventvwr.msc /s in Search Box & hit Enter to open the Event Viewer.

Here, double-click on Applications & Services Logs to see if you are able to evaluate the event description or the cause of the problem.

Hope it helps!
