I want to make a file undeletable

[Ante0]

Yes, I need to make a file "used by Windows".
That fun message you receive when the Exe is "locked" into Explorer.exe at boot.
The reason I need this is because I need to test a program I made.
It will end Explorer.exe, delete the file, start Explorer.exe.
But since I have no file to test it on I don't know if it works properly.

How could I make this happen on purpose?

Does a free program like "Unlocker" give you a list of locked files that you can test your program on? Have a look at the screenshots on their site.
