I found myself among a multitude of users scouring message boards trying to find out why my metro tiles aren’t working after their windows 8 upgrade. After researching the issue I found a list of items that can cause your tiles not to work.
Screen Resolution (Must be at least 1024×768)
User Account Control (UAC must be enabled)
Permissions of the Metro Apps folder
Intel Graphics display driver
Corrupted User Account
Multiple Monitors with different resolutions
I looked over attempting to resolve any configurations listed above that would inhibit Windows 8 Metro tiles to load and was unable to resolve my problem.
I researched the issue further online still determined to not have to do a fresh Windows 8 install which was the only fix for many people experiencing this problem. Spending hours reinstalling and reconfiguring all my programs was simply not an option I wished to choose. I disabled startup items and even deleted some programs I no longer use to no avail. I went into safe mode and even created a new local admin account and much to my dismay I was about to pull the trigger on doing a fresh install.
I still forged through online posts ever more determined to find a couple more fixes I had yet to try when one person suggested to Avast users to update the program (not the definitions). I updated the program, restarted the computer and my tiles immediately starting functioning in the glory that is Windows 8. I went ahead and uninstalled Avast and began using Microsoft Security Essentials which I’ve had much luck with on all my other computers.
