Yep, tried all these "fixes" but none are effective. The only method that I have found to get working Windows 8 installed tiles is to setup another "USER ACCOUNT". Of course, this kills all the tiles that you have for programs that you have installed so you have to go to the programs' "EXE" file and pin it to the "START" to get a working tile.
There seems to be lots of confusion about "Windows 8 tiles not reponding" but the problem is very clear. None of the Tiles installed by WIndows 8 respond when mouse clicked. For example, the STORE tile pops up the green screen for STORE but then just disappears when mouse click to open STORE.
So, I just gave up trying all the fixes since none work to restore working tiles and just setup another "USER ACCOUNT". This is a very "lame" solution but at least I can open STORE and install programs in the new "USER ACCOUNT". Go figure why Microsoft cannot fix this problem.
