DLL file reverting back to its old version in system32 folder.

[Guest]

Am developing an application in VS.

I am creating a dll library file. And I want windows to use my library file,
instead of its own. But as soon as I replace the dll file in windows/system32
with my own, it is automatically changed to its original version.

Could you please tell me how do I disable this?

Rename the backup version of this file in the dllcache folder.

You should be careful when replacing existing system files with your own
files. Anyway, you may want to read
