Thanx for the reply. I checked, I have Windows 7 Home Basic, which seems also not to have the Personalize feature.
I managed though = by going to Control Panel > Appearance > Display > Screen Resolution and doing a search in that screen for "Screen Saver" got me there.
There seems to be no other way to get there in the version of Windows 7 I am using. Why MicroSoft changed a simple operation (which required one right click on the desktop before) to something so complicated defies logic.
Happy New Year!
