I have been using Windows Vista Business Edition 32bit for two month
after a fresh install. A few days ago I began to experience seriou
performance issues during bootup; it began to take a lot more time t
boot up than it was before. What I did was to manually configur
Kaspersky AV 6.0 and ATI CCC 9.3 to start with administrator privilege
during system boot. It was all okay then but when I removed the ATI CC
entry from the startup programs list in Windows Defender I began t
experience serious problems about boot up times. I tried uninstallin
both the AV and the ATI software but that was of no use. Additionally
have to wait all the startup programs to launch before I can initiate
task which requires administrator privileges. Otherwise no prompt bo
displaying allow deny appears even I have clicked on the progra
executable.

Thanks very much for help
