    Hello guys,
    I own a lenovo Ideapad Y550P Laptop with windows 7 Home premium installed.
    recently due to some problem i have formatted the laptop
    and I being over ambitious borrowed and installed a pirated copy of windows 7 ultimate from my friend...
    and used windows 7 loader to install lenovo oem serial and lenovo certificate.
    Now the microsoft caught my copy of windows and warning me to buy genuine copy of OS.

    I want my windows to be genuine again..
    I have a copy of windows 7 home premium
    and a genuine cd key printed back of my laptop.


    Note: I completely reinstalled the os with windows 7 ultimate dvd (I did not use "ANY TIME UPGRADE" so that i can roll back easily)

    PLZ SUGGEST ME A WAY TO ROLL BACK TO WINDOWS 7 HOME PREMIUM WITHOUT REINSTALLING THE SYSTEM AND USING MY COPY OF HOME PREMIUM DVD

    You gave yourself the answer, just use your copy of Home Premium and use the key. DONE!

    Now what's with the BIG font size, not really necessary... please edit your post and reduce the size.

    anyways all you have to do is this...

    1.Click Start.
    2.In the Search Box, type regedit and press Enter.
    3.Navigate to this registry key: HKEY_LOCAL_MACHINE\Software\ Microsoft\ Windows NT\CurrentVersion
    4.In the right pane, click EditionID and ProductName and give them the value which corresponds to a lower Windows 7 edition. Here is an example:
    Windows 7 Home Premium (downgrade from Windows 7 Ultimate to Windows 7 Home Premium)
    EditionID: HomePremium
    ProductName: Windows 7 HomePremium

    5.Start your Windows 7 installation by inserting your Windows 7 Disc.
    6.Now, Select Upgrade as type of installation. Follow the instruction on the screen.
    7.Reactivate your operating system.

    I even Tried to Upgrade the os from ultimate to home premium and then i got an error message saying
    "Windows 7 Ultimate cannot be upgraded to Windows 7 Home Premium. You can choose to install a new copy of Windows 7 Home Premium instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Home Premium, click the Back button in the upper left-hand corner, and select “Custom (advanced)”."
