How to Fix System Restore Error 0x800700b7 in Windows 10

2. Disable/Uninstall third-party Antivirus program

If the error 0x800700b7 doesn’t get resolved, check whether you are using a third-party antivirus or not. An anti-malware program often interacts with the system files leading to different errors and issues. In case you use such an application, make sure to uninstall it and then only create/use a system restore point. 

Just head over to the Control Panel and select Programs & Features. On the next screen, right-click on the Antivirus program and hit the Uninstall button.

Note: Microsoft provides an in-built anti-malware program that is enough for Windows 10 environment – Windows Security. We suggest using this as it neither lags nor leads to any issue anymore.

3. Run the System File Checker Utility Program

The presence of corrupt system files may also lead to system restore error 0x800700b7. If that’s the case, you may run the SFC tool to scan and repair damaged files on the computer. Here are the essential steps to work on –

• Jointly press Win+R to start the Run dialog. Here, type cmd (Admin) and press OK to launch the Command Prompt with administrative privileges.
• Type sfc/scannow near the blinking cursor and hit Enter. The command-line program starts working on the issue immediately afterward. 

• This will rigorously look for corrupt files/folders and repair the same (if there are any).
• Since this takes a few minutes to complete the whole scanning and repairing process, wait accordingly. 

Once over, Reboot the PC to implement the recent changes. 

4. Boot into Safe Mode and Run System Restore
