My friend's computer is originally pre-installed with Windows XP with the COA on the CPU.
Then they upgraded the OS to Windows Vista Home Basic by purchasing the full upgrade of Windows Vista Home Basic with a new COA.
Now, the computer loads very slow and they want it back to XP.
My question is,
If ever I uninstall Vista on that computer, and re-install Windows XP can I use the old COA of the computer on that PC?;and
Will I be able to use the Vista COA on another PC?
