Windows activation . . .

In the Windows activation status page is it still showing as activated, or do you have something like 3 days to do it in?

 

Windows Vista Activation

I have 4 sytems in my home running vista(1 ult.-3 prem).The ultimate & 1 premium took SP1
wthout a hitch.1 premium required re-activation?,The other premium did not list SP1 in windows up-date,So i manually installed it without any re-activation required.
Also have to add that SP1 has increased performance in every comp.The ultimate machine actually got a 1,100 point increase in 3d 06 without any other changes at all.

You can use a Windows key as many time as you want provided it's only on one computer at a time. If the automated activation fails, just call the number it provides. Six minutes later, you're activated again. If it asks you how many computers it's on, just say "one" and you're golden.
