When ever I try to download any app from Windows Store, The download stucks in middle or be pending or downloading forever. Sometimes it's displaying that "To use windows store you need to restart your PC to install one update".But after I restart and open store again. it's all the same.Please tell me how to get rid of this problem.

Hi,

Please try to the following:

1: Reset Windows Store cache

  

a) Press the Windows + R key on the keyboard.

 

b) Type "Wsreset.exe" and press Enter.

  

Note: When you reset Windows store, all the apps in the windows store will get refreshed.

 

 

2: Test the issue in Clean boot.

  

To help troubleshoot error messages and other issues, you can start Windows 8 by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.
