I changed my home pc's logonui, it changed easily, that xp is i think Windows XO SP2

Now when i pasted the same file (4.something MB) in my office system32 folder, it changes back after sometime

please help, theres no extra software installed???

short version is that windows system restore is restoring the file

you can use this utility to replace the file for you

there are ways to manually do it but this ones kinda nice cause it has undo features and such

can u tell me the manual way

is the software (the easy way u mentioned) a freeware or trial

This IS THE easiest way to do it and it is freeware.

Just give the link a look it's not all that hard!

Disable Windows File Protection.....before replacing any system file.

Open Command Prompt and run this command



It deletes Dll Cache and also free space more than 500MB..... Now replace the file and ignore the System files protection dialog box.

thanks guys all of you for posting

Much, MUCH easier solution:

Don't replace logonui.exe. Name the new one logonui2.exe or something. Then, open regedit and go to HKLM\Software\Microsoft\Windows NT\Current Version\Winlogon and find the UIhost string. Change its value to logonui2.exe or whatever you named the new one. That way, not only do you not need to worry about windows file protection, you also have the original if you want to switch back or if something goes wrong with the new one.
