I do not use registry cleaner, I use another program.
So the only solution is to do a complete system restore? That is unfortunately out of the question, i installed ccleaner the day i received the computer.
I thought this issue was supposedly fixed with newer builds. In late 2009 it was claimed the bug was fixed in the windows 7 bug thread. Thats why I used ccleaner.
Now i have a broken task scheduler and is there any promise it will not break it again? As mentioned in the task scheduler bug thread it was supposidly fixed which i soon found it was not.
There has to be another fix other then complete system restore.
