Hello there,
Can you share any error message or event ID that you have noticed?
The system restore error 0x800700b7 may be caused by various reasons, such as the antivirus software, incomplete software installation leaving invalid registry entries, corrupted system files and so on.
Is there anything in event viewer?
I would suggest you to use proc mon to identify if there is nothing on the event viewer.
Process Monitor is an advanced monitoring tool for Windows that shows real-time file
system, Registry and process/thread activity. You can get the tool from here

System Monitor (Sysmon) is a Windows system service and device driver that, once installed on a system, remains resident across system reboots to monitor and log
system activity to the Windows event log.You can get the tool from here

Hope this resolves your Query !!
