In Display Properties under the Themes tab, select a new theme and Apply/OK that. It will get you back to a controlled display where you can start customizing settings again.
Although it is tedious and time consuming, I found that changing such settings is best done one at a time, and noting what I changed it from. Otherwise you can change so much that it is difficult to get back.
I was changing my advanced display settings: text size in the active wiondows, etc..
but now my internet explorer window is really strange. every site appears in large fonts, almost no colours or images, just like i was using win95 or somethng like that. how can I completely restore windows visualization settings without loosing any info?
Thank You very mich
