Recently we posted about a few Windows 7 SP1 details which were officially announced by Microsoft.
Now it seems that a beta build of Windows 7 SP1 has been leaked. Chris123NT @ GeekSmack has posted some screenshots of Windows 7 SP1 Beta build.
The build number is 6.1.7601.16537.amd64fre.win7.100327-0053 which means it was compiled on March 27th, 2010.
The installation procedure is very much similar to Windows Vista SP1 and SP2 but a bit faster.
As usual its going to leak on various sites very soon but you should not download the leaked build as it might contain malicious items as a bonus gift.
