Windows Update simply installs a newer version of whatever files it is working with. It does not open the DLL and change it.

If you want to know how to write a DLL, it is not too hard. You can do it in Visual Basic 6 or .NET and C++ as well as other languages.

Hi There,

Here is more information.. While patching an important dll such as user32 or any dll file or say any existing file which is in use .. ... then the OS while boot process replaces these files with the latest one.

you can also do the same if you want to replace some dlls... there is function call "MoveFileEx"

Thanks,

To replace a Windows Shell file, all you have to do is close Explorer.exe which will temporarily disable file protection. Then when you restart Explorer.exe just click "no" when it asks you for the protection prompt.
