Windows 10: System restore Error 0x80070091

Hi,


I was trying to perform a restore to fix
my favorites list menu and got this error.
I ran chkdsk C: /f /r /x and Windows Resource
Protection did not find any integrity violations.

Running WIN 10 Pro V 1607 Build 14393.693


I'm hoping somebody could help me
resolve this issue.


Thanks!

:)

 

Windows 10, Black Screen

FWIW + FYI:

That's a known issue. See this pinned thread:
System Restore error 0x80070091

 

Is Microsoft doing anything about this??

Hi skeetz

There is a very similar thread that was just post in the last week. Could be some answers withing.

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

OK great thx Ken...I missed that...will go check now

 

Not sure if you are running any AV aside from defender, but some of the AV's tamper protection that prevents changes to the AV files. This causes the error of not being able to do a restore. If you are running an AV, check to see if it has this feature & how to disable it while doing a restore.

 

No A/V other than Defender running here on either machine. It used to work fine and now it doesn't. IMHO MS screwed something up like they did with the Registry Editor quite some time back. It took them a long time to fix that but the good news is that they did eventually fix it.

 

I tried the solution over at that other thread but it didn't work for me...I just ran system restore again
and got the same error message. I can get the 1st 2 commands to work, but when it comes to deleting
or renaming the folder...for rename I get all access denied right down the line and for deleting it says
file/folder can't be found. I have Malwarebytes but it is set to manual.

 

I attached a copy of what each command generated when in safe mode

Can somebody take a look and see what I am doing wrong please

 

Exact same error on two PC's I have here, both running 10 Pro. First time I've tried to use System Restore since both were updated with the Anniversary Update. Worked fine prior to 1607, so don't know if it was that update or something Microsoft patched since?
Anyway reported it to them on Friday - hopefully they'll listen and come up with a hotfix or patch...

 

I get the error on 1 machine with Pro and 1 machine with Home. Same here, haven't had the need for system restore recently, and then when I needed it, it didn't work. Glad I had a Macrium backup. *Smile

 

i had different error code but I was getting the same screen shot.

Double, triple check that you are the administrator and run system restore in save mode.

It worked for me.

Try this fix from Microsoft tech - worked for me...
Go here: https://www.microsoft.com/en-us/soft...load/windows10
Click on the second link 'Download tool now'. Run the Media Creation Tool on your desktop and follow all the instructions. Download will take a while, but when it's finished and you click to continue make sure you choose to 'keep all your apps and settings' when asked (it seems to default there anyway on an existing installation). Basically it'll re-install the latest version of 10 over your system, but otherwise all will be exactly as you left it, and system restore works fine...

 

How did you check that you are THE administrator?
How did you run it in safe mode?
