I had Windows 7 Ultimate on my Computer. At the Setup it created a 100 MB sized "System Reserved Partition". I upgraded my operating system to Windows 8 and now, when I modify my system files (shell32.dll and regedit.exe) there is an error message being shown:
Not enough space to change the windows system files
I searched in the internet and the Windows 8 "System Reserved Partition" should be 350 MB.
How to expand the system partition? Or how to avoid this error somehow?
