Fixing Broken Windows 10 Apps

I have another Windows 10 tip that seems to be a hot topic in help forums but doesn’t have a consistent fix.

The problem I had was I tried to bring up the default Windows calculator, and it wouldn’t run. Since I had fiddled with the default Windows 10 apps before, I figured I just needed to re-install the calculator app. When that failed, I tried to brute-force reinstall all Windows 10 default apps, and that resulted in ALL of the windows 10 apps becoming unusable.

The issue is that some of the Windows 10 apps are super annoying, so many people have been trying to uninstall one or more of the default apps. Unfortunately under the current build of Windows 10, the installer appears to be badly broken so both uninstalling and attempting to reinstall the apps can make all of the Windows 10 default apps unusable. They can’t be uninstalled, they can’t be reinstalled, they don’t work, Windows store breaks, and Microsoft considers them core components so they don’t even show up in the programs and features control panel or settings applets so you simply can’t fix them yourself.

For an example of a badly behaved windows default app, the new Windows 10 photos app will continuously attempt to scan, index, and enhance all images in all libraries. That’s great if the library is only on your local drive but if the library is located on a networked computer, it will saturate your network and thrash the remote library’s hard drive endlessly.

One unsatisfactory workaround is to go to your libraries and remove all libraries on networked drives, but you shouldn’t have to do that if the Windows default apps didn’t have these horrible and destructive behaviors set by default. So instead of removing networked libraries, you can fix the problem by removing whatever Windows app (photos was the worst for me) that is causing the problem.

Of course, many people realize after the fact that they really did want that app back. So the “magic” re-installation command that you could enter into the PowerShell program (run as administrator), as found on a dozen websites and help forums, is:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Detailed instructions can be found on many windows help forums so I won’t go into more detail than that.

Unfortunately under the current mainstream Windows 10 build (as of 16 Jan 2016), that will wreck all Windows default apps and make them unusable. Oops. There are a handful of other approaches to get around this including some registry tweaks and resetting permissions, but the bottom line is that for almost all users, attempting to uninstall or reinstall the default Windows 10 apps will likely break all of them without any way to repair or restore any of them, including the windows store. Thankfully, there is one solution, although it reminds me of buying a new car every time you need an oil change.

The solution for now is to go to the Microsoft Windows 10 installer site here: and re-run the Microsoft Windows 10 installer. It will do just what the original upgrade did, leaving your current apps and files alone and restoring any lost functionality. It can take an hour or more depending on computer and network speed, but I’ve had to do it on 2 separate computers now without any failures, using the online installer.
