Hello nileshpawar4,
I'm John an Independent Advisor and a Microsoft user like you. I want to apologize if you encountered this issue. I understand you want to install Microsoft Store through powershell
Reinstall the Store:
Press Windows key + X
Click and Run Windows PowerShell as Administrator
At the command prompt, copy-paste the following then hit Enter:
Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Launch again your MS Store
I hope this helps! Kindly inform me if my suggestions does not solve the problem. I can provide another solution for you to try.
Sincerely
John DeV
Independent Advisor
