You can disable UAC
As in another thread, a little common sense goes a long way.
First, have an up-to-date backup image file. That's the ultimate fail-safe.
- If you're not sending/receiving Email (your greatest odds of getting infected)
- If you're not opening unknown attachments
- If you're doing limited surfing of trusted corporate sites (Cakewalk, Steinberg, etc for updates/authorization), your odds of getting infected are extremely low.
Could you possibly be infected by a trusted site? Yes, but the odds are minute.
You could also walk out the door tomorrow and a tree fall and land on your head.
If the OP takes proper precautions, he can disable UAC without worry...
