Formatting and Clean Installation of Windows 7 [Tutorial]
In other words, it's "erase everything and start over" for Windows 7, a procedure known as a "clean install" or sometimes as a "custom install." It's the ultimate "reinstall Windows 7" process.
A clean install is often the best way to solve very serious Windows 7 problems, like a virus infection that you can't get rid of completely or maybe some kind of Windows problem that you can't seem to solve with normal troubleshooting.
Also, performing a clean install of Windows 7 is usually a better idea than upgrading from an older version of Windows. Since a clean install is a true restart, you don't risk inheriting any buggy situations from your previous installation.
