I use my most effective weapon Bill, the much feared delete key
Nooooooo Les don't touch that button ......
I plan to do an uninstall of codec files one at a time, and see what happens.
Might take a while, but what the heck, in this heat I am not in hurry to be doing much woodworking anyways.
Worst case scenario. I wipe the drive and do it again

Fortunately, I have not bothered to re install any of my games etc, so I have not lost time there.
Smartest thing I ever did though, was multi partition the hard drive. When I do these formats I am not losing the 80% of my computer that stores all the good stuff eh hehe.
