Using current upgrade licence to re-install Windows 7
Hello, I bought my laptop in 2009 and it had Vista Home Premium 32bit installed; it came with Win 7 upgrade special offer (about 14$) and I bought the 32bit upgrade DVD.
Now it's running Windows 7 32bit Home Premium and it's starting to show VERY strange behavior (there's something that blocks processes writing to disk creating a mess with antivirus updates, internet downloads and other programs).
I would like to re-install it from scratch and port it to x64.
What I need to know is what Win7 x64 disk I will need.
Is it ok if a friend gives me his Win7 retail disk, install it and then put the license key that came with the upgrade DVD?
If not, what version should I use? OEM? Upgrade?
Thank you very much!
