System Restore, on the other hand, does not always operate for some Windows users, resulting in an error message that reads: System Restore did not complete successfully. The 0x800700b7 code is one example.
Antivirus software interacting with System Restore or incomplete program installations leaving incorrect registry entries might cause the 0x800700b7 problem.
This code can also show up as a Windows Update error or, more recently, as a Windows Subsystem for Android in Windows 11, but first, let’s go over the basics of the problem.
What causes the 0x800700b7 error?
Because the causes of this error are so varied, it’s difficult to pin down a single cause, but the bulk of them are connected to corrupted system files that must be repaired in order to rectify the 0x800700b7 error.
This catastrophic issue occurs when you try to upgrade your operating system, restore it to a previous state, or install a subsystem in Windows 11.
Incomplete installations, virus or malware infestations, storage drive difficulties, and other factors might result in corrupted system files.
For Windows 10 and Windows 11, here are a few possible remedies for the 0x800700b7 issue.
How can I fix the System Restore error 0x800700b7?
1. Uninstall and reinstall software
1. Select Settings from the Start button.
2. Choose Apps from the drop-down menu.
3. Click on the recently installed app and select Uninstall..
4. Next, see if the error still occurs, and if it does, try reinstalling the app with all settings intact.
Because the procedure was halted in some way, this problem could be caused by apps that were not installed properly.
As a result, make sure you uninstall any new ones you’ve installed recently and restart the process. Also, if they have any optional components that you haven’t included before, include them this time.
2. Run a System File Checker scan
1. To run Command Prompt with administrative credentials, click the Windows button, type cmd, and select Run as administrator.
2. Then, paste the following command and tap Enter:
sfc /scannow

3. Run the Check Disk utility
1. To run Command Prompt with full privileges, click the Start button, type cmd, and then choose Run as administrator.
2. To run the command, paste it into the command prompt and hit Enter:
chkdsk /r
3. Check Disk may then be able to repair certain corrupt entries. It may also ask you to restart Windows if this is the case.
This operation will scan for disk issues and attempt to repair them, but it will take some time depending on the size of your drive, so be patient.
4. Restore Windows 10 in Safe Mode
1. To begin, go to the Start menu and push the Power button.
2. Select Restart while holding down the Shift key.
3. Windows will reboot, and the Advanced Startup choices will appear. Press the Troubleshoot button to begin troubleshooting.

5. Check to see whether System Restore now works.
System Restore may be prevented from accessing flagged files by third-party anti-virus software. As a result, removing antivirus software could be a solution to the 0x800700b7 issue.
The aforementioned technique is merely an example of how to temporarily disable an antivirus. Your antivirus’s settings for doing so may be substantially different.

How to fix Windows Subsystem for Android error 0x800700b7 in Windows 11?
This is a Windows 11 issue that our readers have encountered while trying to visit the Amazon Appstore through the Microsoft Store.
The problem appears to be with the Windows Subsystem for Android or the Microsoft Store.
You can either install the Amazon Appstore through the Microsoft Store or install an Amazon app to install the Windows Subsystem for Android.
According to Microsoft’s Docs page, the subsystem will be deployed discreetly in the background in both circumstances.
However, in order to access the new shop function, you must be a resident of the United States and have an Amazon account.
Actually, Windows Subsystem for Android is now only available to Beta Channel insiders who have installed Windows 11 Build 22000.xxx build.
Furthermore, in order to use the Windows Subsystem for Android, Microsoft issued additional requirements for insiders.
There are a number of factors that could prevent you from using this function in Windows 11. However, we have a solution in mind that may be of assistance to you.
1. Righ-click the Windows button and choose Windows Terminal (Admin) from the list.
2. To run the command, paste it into the command prompt and hit Enter:
Get-AppxPackage *Microsoft.WindowsStore* | Reset-AppxPackage
3. To open a Run console, hit Windows key + R, type wsreset.exe, and then press Enter or click OK.
4. This step will guarantee that you have the most recent version of the Microsoft Store app and will also reset it. The Windows Subsystem for Android most likely did not install in this scenario.
So, for the time being, the only option is to reset the store and try again. It’s also a good idea to keep an eye out for new updates that may be able to help your PC.
We also have an article on how to install the new Microsoft Store on Windows 11 that may be of assistance to you.
