Good day everyone,
I own an Acer laptop which came with Windows 7 x64 Home Premium pre-installed and, of course, OEM licensed/activated.
I want to wipe the entire HDD and do a clean install of Windows 7 x64 Professional using a Retail ISO.
My question is, how can I get the same licence (OEM activation) after installing Windows 7 Pro?
I read something about installing (not upgrading) an edition of Windows 7 other than the one that came pre-installed on the laptop and get activated by using the corresponding OEM-SLP key (or the COA key, i'm not sure) and a Digital Certificate (some *.xrm-ms file)..... but again I'm not really sure! Can someone please guide me?
Thanks a lot.
