Windows 10 - cannot open any Windows app, settings, updates

2

1

I've been using Windows 10 for something like 2 years already and everything was fine, but recently, around 3-4 weeks ago I noticed I couldn't open Calculator app (the pre-installed one from the Store). I clicked on its icon in Start menu and simply nothing happened.

Then I started investigating and searching. I found some articles on restoring Windows Store apps using some commands in PowerShell (described for instance here). I got many errors during this fix trial: enter image description here

and it didn't help. Currently I cannot even open any "system place" from start menu like "Settings", "Troubleshooting" - I can find it in start menu, but nothing happens when clicking on it.

I've also tried this this Microsoft's troubleshooter which said it cleaned some cache of windows apps and the Store opened, but I still cannot access any apps like before. Also when I tried to install some app in the Store, the download was started and was very slow (~100kb/s) and it closed itself after several seconds.

I'm also not able to open Windows Updates - when I find it in start menu and click "Check for updates..." nothing happens.

I scanned my PC with Avira and Malwarebytes - it found nothing.

Any help would be appreciated.

Have you tried in elevated prompt sfc /scannow? – Daniel Sęk – 2017-10-15T19:34:19.797

Yes, I also tried this one and it didn't help. I'm running it once again now, it will take some time, but I don't think it will help. – Dawid Sibiński – 2017-10-15T19:49:25.533

I've jut run sfc /scannow and the outcome is: Windows Resource Protection did not find any integrity violations. – Dawid Sibiński – 2017-10-15T20:05:32.070

Well this person had the same problem and fixed it - https://www.wintips.org/fix-broken-store-apps-deployment-failed-0x80073cf6-merge-failure-0x80070003-problems-windows-10/ I'm sure there must be a less dramatic approach though. You could try running wsreset or follow: https://social.technet.microsoft.com/wiki/contents/articles/13976.how-to-troubleshoot-microsoft-account-issues.aspx

Check and test with some of the methods I listed here (https://superuser.com/questions/1113553/downloading-windows-updates-takes-forever/1115225#1115225)%E2%80%94yes, still applies to Windows 10. Simple enough to test and confirm since you are having an issue with Windows Updates as well. You might look over some of the stuff I mentioned here as well (https://superuser.com/questions/993233/failed-to-configure-restart-loop-with-windows-7-updates/993243#993243).

@HelpingHand - I've just made this in-place reinstallation of Windows and it seems to work. I have all my data kept and all my issues seem to be solved now. I'll publish my answer here when I'm sure it really works :) Thanks! – Dawid Sibiński – 2017-10-18T14:54:55.623

Firstly, create new user account on your PC and see if there is the same issue.

If not, repair your corrupted user profile:

Otherwise, it could be caused by system components.

Please try to repair your PC without losing anything:

I exactly did in-place reinstallation of Windows, just using this link https://www.wintips.org/fix-broken-store-apps-deployment-failed-0x80073cf6-merge-failure-0x80070003-problems-windows-10/ proposed by @HelpingHand in the comment above. For now it seems to work - all my data is restored and all issues disappeared ;) Finally!

@DawidSibinski Did you have to reinstall all your user-installed software? – dr01 – 2018-05-27T13:26:35.033

1@dr01 no, everything was just fine and installed after this reinstallation. – Dawid Sibiński – 2018-07-16T16:32:23.910
