my laptop os version is 8.1

 all the applications are getting minimized automatically so please show me the solution

 Try running the Apps troubleshooter

Hello Dhaval Ghantala,

All applications automatically minimize themselves? Or only the Windows store app?

If only the Windows Store app ,please run the App troubleshooter as MVP S.Sengupta mentioned.
And we can also try to uninstall and reinstall the Windows Store app and check if the issue still exists.

If not only the Windows Store apps, but also other desktop apps, please try to end the Fast Connect.exe in the task manager.
For more information, please take a look at the following thread similar to this issue.
