MODIFY OR DELETE SYSTEM FILES IN WINDOWS 7

• REMEMBER DELETING OR MODIFYING YOUR SYSTEM FILE's WILL CAUSE YOUR WINDOWS TO CRASH & LOSS OF YOUR DATA. PROPER KNOWLEDGE OF WINDOWS SYSTEM FILE's IS NECESSARY.

• THIS TRICK WILL NOT WORK ALWAYS. SOMETIMES YOU MAY HAVE TO BOOT IT IN SAFE MODE TO DELETE THE FILE & SEE ACTUAL CHANGES. 

• THE WINDOWS SYSTEM FILES ARE OWNED BY TRUSTEDINSTALLER SERVICE BY DEFAULT & WINDOWS FILE PROTECTION WILL KEEP THEM FROM BEING OVER-WRITTEN.

• Open CMD & Type to take ownership as - 

  takeown /f C:\Windows\System32\en-US\winload.exe.mui

• Here we are Modifying the "winload.exe.mui" System File. 

• Now Type command to take rights to delete that System File -

cacls C:\Windows\System32\en-US\winload.exe.mui /G ronnie:F

• cacls command giving full rights to modify the System File. "ronnie" my windows administrator name. ":F" means forcefully you are taking rights.
