Sorry to ask such stupid question's, but all that i've done up untill now is all learned from this fantastic forum and people. Thank you One and All. My question ? Been using Win7 Pro for a few weeks, Activated with kms and it expires in 180 days. What to do before then ? I'm DuleBooting Vista Ultimate32 oem / and Win7 Pro32 kms. Both Activated, all WU's working. Can i Re-Activate using kms ? How? When ? Does this mean my BIOS is already slic2.1? Any help greatfully welcome..
