Thanks for your reply, I have a nvidia GT7950 with the current driver.
Everything was fine untill one day I sat down and it would not recover from
the screen saver(vista) so I hit the reset button and once it restarted the
start menu/task bar were in classic style.
Click start and type in "services", then hit <enter> to open this snap-in.
Scroll down and locate the Themes service. Click on it and either start or
restart it.
Thanks for your input, I just tried your recommendation with no sucess. In
services the themes was already started, I tried stopping then starting again
follows by a restart. When I go to change themes I get "modified" and
"browse" as choices.
Your previous reset may have damaged the driver set. From the Control
Panel/Programs and Features, uninstall the driver set and supporting
software. Reboot (important) and download and install a new set.
