Windows 8 Metro Apps won't open and can not access the Windows Store. I have tried Apps Troubleshooter which said it couldn't fix the problem. I tried to do a Restore. It says it can not fix error. I read a post from another who stated this all occurred when they uninstalled McAfee. They believe that McAfee Uninstalled deleted an important dll. My Acer Aspire also came with McAfee installed and I uninstalled it when the trial period expired. I think that is when my problems started. The other user stated that Metro Apps worked once they purchased McAfee. Does anyone have a solution that doesn't involve the purchase of McAfee?

Method 1:

a. Right Click at the bottom left hand side corner of desktop (on Start screen).
b. Select Command Prompt (Admin).
c. Type “SFC /scannow” and press Enter.
