How to replace windows 7 system files ?

#1 Post by polas » 12 Sep 2013 04:58

Hi I am a newbie so do not ask what and how.
because of limited knowledge of bat programming.

The thing that I want to move the file system successfully copying the explorer.exe explorer.exe_old
and believed to rename it by creating the limbs. old

How do I do that so successfully copied and renamed?
Here's what I tried to change but without accomplishing anything.

Code: Select all

cd c:\
copy explorer.exe c:\windows
cd \windows
rename c:\windows\explorer.exe explorer.exe_old
pause
echo File successfully swapped.


And it says that the system file cannot find the path and of course i got access denied when tried to copy to c:\windows and replace.

First of all, I would strongly advise against altering any system files unless you know what you're doing.

Second, you should rename the old explorer.exe first and then move the new explorer.exe. Right now you're overwriting the old file and renaming the new file, which is not what you want to do.

Code: Select all

ren C:\Windows\explorer.exe C:\Windows\explorer.old
copy C:\explorer.exe C:\Windows\explorer
echo File swapped
pause


Finally, try running the command prompt as an administrator (If you're using Windows 7, search for cmd in "Search for programs and files," right-click it, and select "Run as Administrator")

Then why are you trying to replace system files???

Windows has a file protection mechanism built in to start with...

One thing the OP needs to be aware of is the fact that even if he or she is successful patching a system file
it's not a permanment soulution as Windows updates or future service packs will just change it back again..DP 8)
