Seems like i have good news now to this kind of bug.
About two Months ago a saw an advertisement about a new Supertool which is called "System Mechanic Pro" which does cleaning the Registry, finding Junk Files, repairing broken Shortcuts, align misaligned files on the HDD and stuff like this. So for me as german i first did not have trusted this Supertool which seems to be a Big Deal in the USA. But i started to wonder about this awesome Programm.
When this problem was not related to a Hardwardriver Problem i think that tool fixed this Issue. I had broken Shortcuts as well as "WMI Conflicts" called issues.
I can say now that i did not had this zoom Bug again since around 1,5 months i`m using this Programm.
