Thank you.

You have a few options here.

1. See if you have the Xbox app. If so, launch it, go through the initial set up or whatnot. Once all the way in, it might provide you a list of items with a yellow warning indicating issue with them. It might also provide you an installation option to install it. See if Store app is one of them. If so, you should be able to install it from there.
2. Go to Start > All apps, locate Powershell, right click and "run as admin". Run this command:

Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "_.InstallLocation)\AppXManifest.xml"}

3. If the computer was just set up out of box, you can also consider a factory reset to start over. Hold down Shift key while you choose Windows restart, then go to Troubleshoot > REset this PC.
4. Repair install is another option. To perform a repair istallation of Windows 11 using the Windows Media Creation Tool:

The following steps should be done on a working Windows computer:

Download the Windows Media Creation Tool from Microsoft's official website. https://www.microsoft.com/software-download/win... click on the "download now" button under "Create Windows 11 Installation Media"

Run the tool and select "Create installation media for another PC."

Choose "USB flash drive" as the media to use for the installation and select "Next."

Connect a USB flash drive with at least 8 GB of free space to your computer.

Select the USB flash drive you want to use, and then select "Next."

The tool will then download the required files and create the installation media.

=====================================================

Now these steps will  be done on your problematic computer:

Go to the USB drive via File Explorer, locate and run the Setup.exe file. Ideally, you should disconnect all USB and Bluetooth devices other than mouse and keyboard. Disable any 3rd party antivirus program. Disconnect the internet.

Once you run the Setup.exe file, choose the Install option, and the choose the option that keeps your files and apps.

        Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$ ($_.InstallLocation)\\AppXManifest.xml"}

• To reinstall all built-in apps, copy and paste the following command at the PowerShell window and press the Enter key.

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

• Restart your PC and check if the apps are working properly.

I appreciate that mistakes can be made, and please do correct me if I'm wrong, but surely as a Microsoft Community Support Specialist you should realise that this PowerShell is not correct? If you run this, you will receive the following:

This is because you have included an unnecessary space after -Register. For your second example, this should read as:

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

Running this will actually result in app deployments rather than a screen full of red stating that the file location does not exist - in this case, the only failures should come from resources that are being used by currently open apps:

Hope that helps.

Fix problems with apps from Microsoft Store

Microsoft Store doesn't launch Trouble finding

Microsoft Store in Windows 10

So, the Windows Store is now back with me. As far as there was no complete solution in any single answer, here is my solution. Thanks for all who participated.

What you'll need

The installed Windows 10 with apps (further it will be references as "good windows"). You may use "friends computer". I used the VirtualBox virtual machine and an appropriate setup image. There is no need for license key for this: Win10 can be setup without key and activation, it'll be enough for this solution.

Step1

Take the ownership of "C:\Program Files\WindowsApps" folder as adviced here.

Step2

Open WindowsApps folder. Check, if there are next folders:

• Microsoft.VCLibs.140.00_14.0.22810.0_x64__8wekyb3d8bbwe
• Microsoft.VCLibs.140.00_14.0.22810.0_x86__8wekyb3d8bbwe
• Microsoft.NET.Native.Runtime.1.0_1.0.22929.0_x64__8wekyb3d8bbwe
• Microsoft.NET.Native.Runtime.1.0_1.0.22929.0_x86__8wekyb3d8bbwe
• Microsoft.WindowsStore_2015.7.1.0_x64__8wekyb3d8bbwe
• Microsoft.WindowsStore_2015.701.14.0_neutral_~_8wekyb3d8bbwe

If some of them are not presented there - copy missing ones from good windows and copy here.

Note1. For those who are in italic: I'm not sure that they are required, I processed all of them, may be they are not required.

Note2. For WindowsStore folders there may be another version, as it can be seen in @Fase answer.

Step 3

Open Windows Powershell.

Register every folder (one by one, except the last one!) in the order they are presented in above list with the next command:

Add-AppxPackage -DisableDevelopmentMode -Register "C:\Program Files\WindowsApps\*FOLDER*\AppxManifest.xml"

Example:

Add-AppxPackage -DisableDevelopmentMode -Register "C:\Program Files\WindowsApps\Microsoft.WindowsStore_2015.7.1.0_x64__8wekyb3d8bbwe\AppxManifest.xml"

You'll be close to success if the command with WindowsStore will give no errors. Others may return errors if they were allready registered.

Step 4

If Step 3 was successfull, you'll be able to find (Press WindowsKey then type Store) the Store application in the Start Menu.

Try to start it. If it will work - congratulations. If it will be shown for a while and then closed - see Step 5.

Step 5

Grant permissions for "ALL APPLICATION PACKAGES" account to WindowsApps folder as adviced here.

That's all Folks!

Hi, I'm Elise, a fellow user like yourself and I'd be happy to help with your issue.

Other users have had a similar issue to this, could you please try follow these steps to re-register the store app.

Could you open the powershell app as an administrator and copy in the following command and press enter

Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Now reboot your PC and this should allow you to use the store app again.

If this doesn’t work the next stage I would suggest is a repair upgrade, you can find steps on how to do this here:
