Windows 10: Can apps that were deleted using Powershell be restored by resetting?

Hi guys!

My story is kinda crazy, but I'll try to summarize it in bullet points:
* I was having problems with the calendar app, hence I tried removing it
* I stumbled upon PowerShell and removed the app (along with mail)
* I can't open Windows store afterwards
* I tried following some restore fixes online, but to no avail
* I downgraded to Windows 8.1 in hopes to undo my mistake
* After reverting to 8.1, the calendar, mail, people, viber, and fresh paint app don't function anymore.
* I am re-downloading Windows 10 to see if it could miraculously make things right again
* If it does not change, my last resort would be to reset my PC. Hence the title of this post

Thank you for reading! Hope to hear from ya'll soon.

Best regards,



:)

 

since fall update no calculater and can' access windows store

Re-register the missing apps using PowerShell – If you have a lot missing apps, advanced users can instead attempt to restore all of them at once using the following PowerShell commands. Note, however, that if Steps 1 and 2 were already attempted and did
not restore your missing apps, this PowerShell solution will also likely not succeed.

In Cortana, type PowerShell. In the search results, right-click Windows PowerShell and select Run as administrator.

In the Powershell window type the following commands. These steps may take a few minutes to complete.

reg delete “HKCU\Software\Microsoft\Windows NT\CurrentVersion\TileDataModel\Migration\TileStore” /va /f

get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "\appxmetadata\appxbundlemanifest.xml")}

$bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname

get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "\appxmanifest.xml")}

Once the PowerShell commands are completed, the apps should appear in the app list, and can be pinned to the Start Menu.

How do I restore files that were deleted by mistake?

Which files?

 

I'm not sure about reset (I've not tried it but it surely should work) but I deleted the store and restored it like this:

Copy everything Microsoft.Windows.Store*, Microsoft.VCLibs* and Microsoft.NET.Native.Runtime* from C:\Program Files\WindowsApps on another machine and then register them using using Add-AppXPackage. I used versions from a 10532 VM to reset the store on 10120 and apart from being a newer version of the store it worked fine.

Alternatively you could do an in place upgrade (from 10 to 10) - that will restore your apps but leave any programs/settings you have. This may be easier if you have an ISO or USB installer for 10 - just mount it and click on setup.exe.

Appreciate the suggestion! Things went back to normal when I reverted back to Windows 10. I guess it's an easier fix for a non-techie guy like me *Smile
