Fresh installation of Windows 8
Applied all patches (70 or 80)
Created user account Member of Super Users

Clicked on Windows Store Tile
Said there were a load of app updates
Selected all of them and said to install
One or two installed then three stopped saying they couldn't install. Three were still installing and the rest were pending.
Waited a long time and nothing progressed.  Green bars in the same place.  Right clicked on each one and selected stop installation.  All of them stopped except for one which didn't show the bottom bar when it was right clicked on.
Closing the store (dragging top all the way down) and opening it again showed the same app installing (but it wasn't).
Signed out and restarted machine.
Go into store and nothing is shown as needing an update.

Computer is hardwired to router which is connected to a cable modem.

Is there someway to recheck for app updates?

Hi,

Have you tried to connect other network enviroment for test? According to your description, this problem probably caused by network problem.

In addition, you can try to use WSRESET command to clear Store cache for test.

Win+R, open RUN, type WSRESET, press Enter.

If problem persists, you can try to use APP troubleshooter to fix it for test.
