Windows 10: How long does a system restore take?

How long does it take to restore Windows 10. I spent a good portion of the day trying to restore my wife's PC because ya'll insisted on giving her Edge with you latest update and destroyed all her favorites. So far I'm on my third try and haven't been successful yet.

1. Ran system restore for over an hour. No luck because I forgot to turn off Malwarebytes.
2. Ran system restore for over an hour. No luck because I forgot to turn off Defender.
3. Been running for an hour now and it ain’t done anything. It’s still initializing and now it says it's restoring the registry.

How much longer and how many more "gotcha's" do I have to overcome to get back her favorites and get rid of Edge?

:)

 

If a system restore restores the registry to how it was before, then how come a trial version of a program does not reset?

I do the following in the given order:

1. Create a system restore point. There is a note of what the registry looks like
   
2. Download a program which has a trial of X days
   
3. When that trial runs out, use system restore to return to the previous point before the program installation
   

After these steps, the trial for the program does not reset, even though the registry returned to how it was before. Why is this?

 

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.

 

System Restore fails: AppxStaging %ProgramFiles%\WindowsApp 0x80070091

Steps taken.
Part 1/
Install W10. User -Test (No additional updates. No OEM drivers)
Create Restore Point -"Pristine"
Make a system alteration. ie; D/L and Install Google Chrome.
System Restore to RP "Pristine". (Note: Chrome should be gone.)
Successful. Chrome is gone and Edge reset. ??? Chromesetup file removed from \downloads??? Why???
New Restore Point - "Undo Restore" created by system.

Step 2/
D/L and install KB3213986. Reboot.
Make a system alteration. ie; D/L and Install Google Chrome.
Create Restore Point - "Update 1 Chrome"
Make a system alteration. Uninstall Chrome.
System Restore. (Note: Chrome should come back but may not work correctly.)
Fail. 0x80070091

To me that represents a conclusive result.

The next obvious thing to do was to roll back the Update, assuming that this will fix System Restore. However, rolling back the Update DID NOT restore the functionality of System Restore. So now my confident claim, above, is a bit shaky. If performing the update does in fact cause the issue, removing it doesn't put it right.

So now, the next obvious thing is to perform the WindowsApps rename or deletion process, to apply the fix, and run a series of testing to see if System Restore becomes stable.

Results.
Performing the WindowsApps rename fix, instead of deleting it this time, once again resulted in System Restore operating correctly. I have been able to install the remaining updates and flip back and forth between Restore Points without issue.

At this point I am done with it. My testing shows that:

• It is update KB3213986 that causes the problem to occur in the first instance.

• Rolling back the update does not correct the problem.

• Performing the known fix returns System Restore functionality.

• For how long, we don't yet know.

Should you wish to rename the WindowsApps directory rather than delete it, the attrib WindowsApps -h command line can only be performed after the icacls command line.
