You bought a new computer with a pre-installed Starter/Home Premium/Professional (Genuine) version of Windows 7 and want to upgrade to Professional or Ultimate for free in as few as 10 minutes .
Your pre-installed version of Windows 7 actually includes all files that are necessary to perform an in-place (local) upgrade without downloading anything from the internet. One simply needs unlocking features included in higher versions.
You can upgrade Windows 7 from/to:
Here's what you
need to do:
To upgrade from one edition of Windows 7 to another edition of Windows
7, use Windows Anytime Upgrade. On your PC, open Windows Anytime Upgrade by
clicking the Start
button, typing Windows Anytime Upgrade in
the search box, and then clicking Windows
Anytime Upgrade in the list of results.
You will be presented with a screen offering 2 options, one of them suggesting
you have a valid Windows Anytime Upgrade key.
Once the key has been copied into the appropriate
field, it will be verified by MS and the upgrade process will take place. The
whole process actually doesn't last longer than 10 minutes, your computer will
reboot once or twice. Upon restart, you will notice it now runs a genuine
higher version of Windows 7.
* You can use Windows Anytime Upgrade to upgrade
from a 32-bit version of Windows 7 to a 32-bit version of Windows 7 and from a
64-bit version of Windows 7 to a 64-bit version of Windows 7, but you can’t
upgrade from a 32-bit version of Windows 7 to a 64-bit version of Windows 7 or
vice versa.
* Windows Anytime Upgrade isn’t available in all
editions of Windows 7 - obviously not in Ultimate version.
