I am trying to upgrade Windows 7 7100 x64 to Windows 7 7127 x64. After inserting the Windows 7 7127 x64 DVD and proceeding with the installation, I got an error message saying 'You can’t upgrade this prerelease version of Windows 7. Go online to see how to install Windows 7 and keep your files and settings.'
I followed the link but I got the below list in which I am not interested:
how to:
1. Upgrade from Windows Vista to Windows 7 ;
2. Migrate files and settings to a new computer;
3. Upgrade from Windows XP to Windows 7 ...
So, can you please tell me how can I upgrade from Windows 7 7100 x64 to Windows 7 7127 x64?
