Oh alrighty, didnt see that one, sorry. ^_^
It doesnt bother me, and I dont bother it. If it aint broke, dont fix it I say.
A number of ways.
1.If you’re talking about going from windows xp bubble format (assuming you have xp) to windows classic or anything else youd go to Start>Control Panel>Display>Themes, and work from there.
2.Modify the GUI files for windows (bad idea unless you know what you’re doing lol)
3.Get a program that does it for you (Style XP or WindowBlinds, but I’d highly reccomend WindowBlinds over Style XP. Style XP modifies the GUI, so it can be harmful, but WindowBlinds merely puts a skin over the current GUI, so its reversible.)
Thats all I know, hope that helps.
