My Windows powershell stopped working. Also system restore error

Redbatman · 29 Mar 2017

Okay so today when I was using my Desktop. All of the sudden nothing was working, Youtube wasn't playing any audio, I couldn't bring up task manager, etc. So I had to do a shutdown though it had to be a hard shutdown since it wasn't shutting down after a minute.

So to be safe I did a system restore through advanced startup and well it didn't work and it gave me the error 0x80070091 which shocked me and apparently I'm not the only one

System Restore error 0x80070091 - Microsoft Community
Win 10 System Restore Fail 0x80070091 - Microsoft Community

So yeah should I wait for Microsoft to fix system restore or try it myself?

Also for the Windows Powershell not responding what should I do about that? I already did an SFC Scan and a DISM and both came back good.

Hi, there is a very long thread on this forum about 0x80070091, where some have found a solution. However, that's not your major problem.

Given your various symptoms and what you've tried I would suggest an in-place upgrade repair install: there's a chance that may also fix your system restore problem.

Precede it with this in case sthg has happened to your file system:

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Make sure the result is clear or fixed- else do not proceed.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

An In-place upgrade repair install will fix many things, but not those where the settings are not changed by the procedure.

For this you need an installation medium with the same base build as you have installed, and x64 if you have a 64 bits OS, else x86 (32 bits).

You should also make sure there's at least 500Mb of unallocated space on your system disk.

Recommendation:
Before you perform the following major repair procedure, do create a disk image (see below).

Repair Install Windows 10 with an In-place Upgrade - Windows 10 Installation Upgrade Tutorials
- this includes a link from which you can obtain a Windows 10 iso file (" download a Windows 10 ISO"), or create a Win 10 bootable medium.

I would recommend creating the bootable medium, as this can be used
- for any future in-place upgrade repair install
- to boot from and use its recovery options should Windows become unbootable.
- to clean install Windows

This will refresh Windows, after the manner of a Windows installation.
- all/most associations will be unchanged
- all your programs will be left installed
- However: if you have installed some on a 2nd drive, these must be uninstalled or reinstalled on C: - else you will get an error message that you can not keep my apps because they arein an unsupported directory.
- no personal data should be affected
- you will lose any custom fonts
- you will lose any customised system icons
- you may need to re-establish your Wi-Fi connection
- you will need to redo Windows updates subsequent to the build you have used for the repair install
- Windows.old will be created
- system restore will be turned off- you should turn it on again and I recommend you manually schedule a daily restore point.
- you will need to redo any language downloads including the display language if you changed that)
- inactive title bar colouring (if used) will be reset to default
- if Qttabbar is installed, you need to re-enable it in explorer (Options, check Qttabbar)
This is one of the better features of Win10: as each major build comes out, that's your updated reference build, and as updates are mostly cumulative, there will be few to do.

Please consider using disk imaging regularly. It's a brilliant way to
- preserve your system (and your sanity)
- back up your data
- restore your system to a previously working state in a relatively short time

Recommended: Macrium Reflect (free/commercial) + boot disk/device + large enough external storage medium.

Ok, that's good, so you can proceed with the in-place upgrade repair install if happy to do so.

Well since it came back good there is no need too right. I did also a system restore last to a restore point I made last night then used it 20 mins after and it worked fine, but it gave me a windows did not shut down properly error strangely. But yeah I'll only use system restore if necessary.

For everything else should I just chalk it up to shit happens?

dalchina · 30 Mar 2017

Well, there's a surprise... so you're saying now system restore has suddenly started working, and having used a restore point your problems have vanished.

Chkdsk did some minor work:
Stage 3: Examining security descriptors ...Cleaning up 2113 unused index entries from index $SII of file 0x9.Cleaning up 2113 unused index entries from index $SDH of file 0x9.Cleaning up 2113 unused security descriptors.Security descriptor verification completed. 63186 data files processed.

But otherwise- who knows?

Redbatman · 30 Mar 2017

Well I remember in another post you said that if you had a bad restore point system restore wouldn't work at all so I deleted all my restore points and made a fresh one manually and it worked.

Also I did another SFC scan and a DISM scan last night and still came back with no issues.

This time I think you've been lucky.. so if all is working, if you haven't yet done so, now's the time to start using disk imaging routinely (e.g. Macrium Reflect (free) )+ its boot medium + external storage for images - then should sthg go wrong, you have a good chance of restoring your PC from your image.

Much more comprehensive and reliable than system restore, and applies to data disks/partitions too.
