I found a solution to upgrade to Windows 7 Professional - faster than clean install slower than windows anytime upgrade...i think.
I have tested this on virutal box and it worked fine. it was like updating from vista to windows 7 though
the solution is not the "correct" way but it is legal
What you must need: if you don't ALL of these. STOP and get them first
---windows 7 starter or home installed
---windows 7 Professional DVD from MSDNAA (burned from server/download)
---A vaild MSDNAA product key.
---Time about avgerage:1 hour max 4 depending how ssssllllloooowww your computer is
---access to an administrator account
IMPORTANT:: There is no easy turning back once done. If you don't have a vaild, never been used product key you need to clean recover your computer somehow…(clean install to windows 7 home)
Step 1: Backup – recommended but not a must
backup anything and everything that is important.
start Registry Editor (RegEdit).
go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion
change the following (write down anything you change, what it was and what it is now)
EditionID to "Professional"
ProductName to "Windows 7 Professional"
Step 3: put in the windows 7 Professional DVD
run setup.exe from DVD
Choose the option upgrade…
Press agree and next and you will see it upgrading
after all them restarts change your product key to activate it…if it fails then it has already been used or you incorrectly entered it.
Done. windows 7 Professional installed.
