I installed patch 3 Windows 7 after reading answers form this link on MakeUseOf to increase my usable RAM from 2.95 GB. Instead, it has created a whole new secondary operating system called Windows version 6. Something with 128 GB space. How can I uninstall this patch?

    Hello, one way would be to edit your boot configuration.  You would have to delete the entry created when you installed the patch.  You could either do this by using the BCDEdit command which is a command incorporated with windows vista/7.  You do not need to install anything:

    Here is how it works:

    Or you could use the following Visual BCD editor to delete the entry and fix your boot menu.  I am assuming that when you start up your computer, it gives you a choice to choose which system to log to.

    Here is a little tutorial about how to use the program:

    Once the above is done, it is just a matter of looking for registry entries added when you installed the patch.  I would also run a scan with system file checker.  When you ran a patch like that, it changes some files in the kernel for sure.  To run system file checker do the following:

    -- click on orb
    -- type cmd in search box
    -- highlight entry and right click on it, select run as administrator, then press enter
    -- once command prompt opens, type the following:

    sfc /scannow

    -- let the scan finish.  Make sure to keep your installation disc ready in case it asks for it.

    I doubt the entry will be there but you can check if it added an entry in the add/remove menu:

    -- click on start
    -- control panel
    -- under Programs, click on uninstall a program
    -- scroll down to see if there an entry for patch
    -- highlight entry if any
    -- click on uninstall
    -- restart your system

    Hopefully you learn something from this experience.

    if you open system configuration (on run type msconfig) then click on boot you have to see two boot options one is for the normal windows and the other patch, perhaps you can delete from there. Also the patched kernel file "ntkrlICE.exe" in the folder "C:Windowssystem32" can also be safely deleted.
