Replace logonui.exe

[JayDogg]

Ok Im writing a batch file to replace the logonui.exe in (C:\WINDOWS\system32), if you just copy and paste your logonui.exe over windows logonui.exe, windows will check (C:\WINDOWS\system32\CatRoot2) and (C:\WINDOWS\system32\dllcache)which is hiden) and convert/replace your logoui.exe with the original windows logonui.exe. So if you move all of (C:\WINDOWS\system32\CatRoot2) and (C:\WINDOWS\system32\dllcache) (Directory+SubDirectorys+files) to (C:\CatRoot2) and (C:\dllcache) then copy over your logonui.exe to (C:\WINDOWS\system32) windows doesnt convert/replace your logonui.exe. Then you can move (C:\CatRoot2) and (C:\dllcache) to there original directory (C:\WINDOWS\system32\CatRoot2) and (C:\WINDOWS\system32\dllcache) and there you go you have replaced your logonui.exe with out restarting your pc in safe mode with command promt (most common way to do it). So my problem is I dont think my batch script can copy those directorys cause somthing has a handle on them (a program or the system is using them). Anyone know a way in a batch script you could kill/unlock the handles then copy the directory over. I think winlogon.exe has a handle on (C:\WINDOWS\system32\dllcache) and svchost.exe has a handle on (C:\WINDOWS\system32\CatRoot2). I used unlocker to unlock them then move the directorys manually, then moved my logonui.exe manually and then moved the directorys back manually to test my work and everything worked like a charm my logonui.exe was replaced and working. So now I want a batch file to do it all for me but like I said I think the fact that (C:\WINDOWS\system32\CatRoot2) and (C:\WINDOWS\system32\dllcache) are being used is stopping my batch script from working.

So if you have any ideas or know how to unlock a file or directory with a batch file please help me out =)

My batch script looks like this right now

xcopy "C:\WINDOWS\system32\CatRoot2\*.*" "C:\CatRoot2" /f /I

xcopy "C:\WINDOWS\system32\dllcache\*.*" "C:\dllcache" /f /I

rd /s /q "C:\WINDOWS\system32\CatRoot2"

rd /s /q "C:\WINDOWS\system32\dllcache"

xcopy "C:\logonui.exe" "C:\WINDOWS\system32\logonui.exe" /f /y

xcopy "C:\CatRoot2\*.*" "C:\WINDOWS\system32\CatRoot2" /f /I

xcopy "C:\dllcache\*.*" "C:\WINDOWS\system32\dllcache" /f /I

rd /s /q "C:\CatRoot2"

rd /s /q "C:\dllcache"

which Im not even sure if that is the right way to do it cause Im not the best at batch scripts just have some basic knowledge
