is it? for some reason my oem version allow me to install more the 1 pc w/o need to activated (some how its auto activated)

It will run for 30 days and then you will be locked out of your pc. Been there. Done that.
My advise, transfer your important data before that happens.

What happen if the PC need to format due to serious virus attack OR hardware malfunction OR whatever reason. Surely Microsoft allows us to get the OS activated right? Which PC can gurantee that it dont need reformat for the rest of its PC Life. I am also using OEM with my new PC and with my PC having so many problems, reformating is just a matter of time.
Only have my pc with OEM for a week and had already reformated and reinstall Vista 3 times. No problem encountered so far.

Pc 1 = Have os.
If pc 1 is being sent to reformat.
And you want pc 2 to have the os.
Pc 2 is allow unless pc 1 don`t have it.
Meaning 1 lisence 1 pc.
You can transfer the lisence to the other pc. by uninstall then install on the other pc.
I am sure it will work with full retail version. But not sure whether it will work that way with OEM.
Never have any problem with XP but this Vista seems to be very different.
