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.

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:

Hi and thanks for reaching out. My name is Bernard an Independent Advisor and a Windows fan like you. I'll be happy to help you out today.

Actually I have the same problem and by following the steps below fixed my issue, I know some of these steps already done, you have just skip it if you think it will have the same result.

Method 1. Repair Windows Store:

1. Go to settings> Update and Security> troubleshoot > Additional troubleshooter> Then click Windows Store apps
2. Temporarily Disable the Anti-virus (If you have third party anti viru)
3. Run Powershell
4. On Powershell(admin), copy and paste the command below:

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

Method 2. repair Windows Store and update components

Open Powershell with Admin or CMD with Admin (Press Windows key + X then click Windows Powershell(Admin))

Copy each line of command to Powershell then press enter (one line at a time)

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"

rmdir %systemroot%\SoftwareDistribution /S /Q

rmdir %systemroot%\system32\catroot2 /S /Q

regsvr32.exe /s atl.dll

regsvr32.exe /s urlmon.dll

regsvr32.exe /s mshtml.dll

netsh winsock reset

netsh winsock reset proxy

net start bits

net start wuauserv

net start appidsvc

net start cryptsvc

-Once done restart the device and check

If none will work from the above solution I suggest to do an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/402753...

1. go to this link: https://www.microsoft.com/en-us/software-downlo...
2. Select Download tool, and select Run. You need to be an administrator to run this tool.
3. On the License terms page, if you accept the license terms, select Accept.
4. On the What do you want to do? page, select Upgrade this PC now, and then select Next.
5. After downloading and installing, it should fix the issue.

Reference: https://www.microsoft.com/en-us/software-downlo...

Note: if you receive error: “This Pc can’t be upgrade, follow the steps below”

Method 1. Go to C:$WINDOWS.~BT\Sources\Panther then delete the file name compatscancache.dat

Then try again or reboot the PC first then try again.

You might not see the folder as it is hidden, make sure to show hidden files first.

Let me know how does it goes and I hope that helps.
