      From what I saw in the command file this patch ads a custom boot entry with a customized kernel executable to Windows and selects it as the default boot option.

      I would like to ask you to open up an elevated command prompt (right-click on "Start > All Programs > Accessories > Command prompt" and select to run as administrator)

      Type "bcdedit" in the command prompt and please reply back the output. With that I may be able to support you with the commands to remove the entry and uninstall the patch.

      The only other way would be to repair the entire boot BCD via the Windows CD/DVD however in rare cases it doesn't work and results in a not bootable installation.


      Hello, as an alternative he can use Visual BCD Editor(freeware) to find out or get rid of new entry added by patch:

      He can also use EasyBCD, but it is paid software:

      perhaps like this
      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.

      do you have graphic card? if so, then the integrated Graphic and the graphic card shared the memory together.. i'm also in 64bit OS. Just like you said, DONT WORRY.. when it comes in running 64 bit application, the OS use all your RAM. The things that it shows the usable memory is that many application that running is 32 bit. Look at your task manager, view the processes... lots of x32.. :)
