As of late, there are a couple of Store apps which just won’t install on any of my Windows 10 machines (One Commander and Open Live Writer in case you are interested).

The message shown is:

The error code is 0x80073CF9, in case you need it.

If you do a search on the error number you’ll find numerous posts and articles explaining on how this error might be solved. As it happens, the error also occurs on Windows Phone/Mobile systems.

One of the suggestions I came across is re-installing the Store app.

Uninstalling a Modern App is quite easy with tools like CCleaner. If you don’t have tools like this, it’s also possible to do this via the PowerShell Remove-AppxPackage cmdlet of course.

However, once uninstalled, how will you install the Store, without having a Store.

A System Restore might help, but I didn’t have any usable restore points.

An easier solution is to re-install the Store app via PowerShell. With the following command you will see all the applications which still reside on your system.

Get-AppxPackage -allusers | Select Name, PackageFullName

One of these should have a name similar to Microsoft.WindowsStore.

You can re-install this app by using the Add-AppxPackage cmdlet.

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsStore_11610.1001.25.0_x64__[uniqueId]\appxmanifest.xml" -DisableDevelopmentMode

Invoking this command, mind the [uniqueId] which differs on every system, installs the Windows Store again. You will be able to find the Store again in your start menu/screen and start it again.

The error still occurs when trying to install these specific apps, so re-installing didn’t solve my issue.

With Windows 10 we’ve gotten a lot of nice little features which help us modifying the theme. There is however 1 option which the team hasn’t implemented (yet). The option to select different wallpapers for all of your connected displays.

I’m working with a triple monitor setup at home and at work most of the time with a dual or also a triple setup. Of course I don’t really need different wallpapers on all of my monitors, but it’s a nice feature.

Luckily we are still able to do this, using the ‘old’ control panel pages which are still available in Windows 10. If you type in the following command inside a Windows Explorer address bar or the Run command window you’ll be able to get there.

control /name Microsoft.Personalization /page pageWallpaper

On this screen you are still able to select your wallpaper for every connected display.

Just a little tip, hope it helps.
