Thanks for the reply, I was wrinting in the Microsoft technet and in the Seven forum 
If I open my OD settings, I can see as existing only a dokc (with 15 tabs) and that dock is without any applet or java or anything else.
I cannot see (Or I'm not able to do
) if the zoomer is on, for sure in my other docks I had the zoomer on.
I have now tried 2 different solution but without any positive result. The first way to solve I tried, it was the System Restore and I tried in 2 different restore point: the first one before IE 9 and the second 2 days ago. In both situation after the reboot I have this advice:
System restore did not compete successfully. Your computer's system files and settings were not changed.
Details: System restore failed to replace the file (C:\Windows) with its original copy from the restore point.
An unspecified error occurred during System restore (0x80071a90)
You can try System Restore again and choose a different restore point.
If you continue to see this error, you can try an advanced recovery method.
So I tried to uninstall IE 9 through Control panel and the specific uninstaller, I did the reboot and .... same situation.
At that point I decided to use newly System restore and I tried in 2 different restore point: same situation than before.
So now I have no idea ..... What can I try?
Overall I think the big problem is about system Restore, if for any serious problem I need to use it, at the moment seems to be impossible.
Please any help will be greatly appreciated.
