He means a hacked uxtheme.dll file...
In theory its the same as xp skinning for windows.

I may get blasted here but I've tried all windows skinning apps and
windowblinds works best for me.
Can't live without having the option to roll up my windows with a right click on the title bar!

Windowblinds also supports alpha channels and no other app at this time does!

It may be a little resource hog compared to the others but also has tons of options the others just dont.

If you got a nice fast machine with lots of spare memory than I would suggest windowblinds first.

If you are looking to use the native xp skinning stick with hacking your uxtheme.dll file.
But you will not get alpha or rollups :(
