It is disappointing that despite the fact Microsoft has been working on Windows 10 Fall Creators Update since April this year when it finally rolled it out, there are some bugs. Some of the early adopters who upgraded to the Fall Creators Update as soon as Microsoft it came out on the stable channel are already complaining.
Some users are already reporting they cannot find certain system apps after upgrading to the Fall Creators Update. Some users are complaining they cannot find apps like Calculator when they search it from the Start Menu or when they run a Cortana search.
Naturally, when you run a systems app like say, Calculator, and you don’t find it on a new version of Windows. You will assume this latest version does include such systems app. So you go to Windows Store to search and install the app. Interestingly, when you find the app on Windows Store, you see that the app is already installed on your system. When you click on open the app, the Calculator indeed will pop up.
Microsoft Quick Fix
Microsoft is yet to issue an official fix, but it has suggested a quick fix to users affected. Microsoft recommends you either reset the affected app(s) or uninstall them then reinstall them from the Windows Store.
Although the most effective workaround to this problem is to re-register the affected app using the PowerShell. Below is a workaround fix suggested by Microsoft’s Meliton Dec on the discussion forum:
“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.
If none of these troubleshooting steps restore your missing apps, you may be able to go back to the previous version of Windows. We will update this forum post as better solutions become available. Check back with this forum post later to see if the problem has been resolved and then retry installing the Fall Creators Update.”
Then again, you could always revert back to the previous version of Windows by going to Settings > Update & security > Recovery > Go back to your previous version of Windows.
Please note the revert to previous Windows version option will only be available for the next 10 days after you upgraded.
