The System Restore is another big headache, if you do something that Windows didn't liked, Windows will restore all destroying one or more hour of your work of personal configuration.
The only way the stop Windows destroying your work is to delete all the system restore folder, but this folder is hidden, not shown in Windows and Windows do not allow any access to it.
The only way for deleting this folder is booting your computer with DOS or Linux.
Of course once you have deleted the restore data folder is no way back, if you did something wrong maybe you'll need to install Windows again.

Stupidity also evolves!
