How to Delete MpSigStub.exe?

[DemonDragonJ]

Recently, a folder appeared on my hard drive, without me having done anything to make it appear. Its name is a random string of letters and numbers that I shall not bother to memorize, but it contains a single file, called MPSigStub.exe. As far as I can tell, that file has no purpose, but I cannot delete it, even when I use a file shredding program, which greatly bothers me. The file itself is not harming my computer, but it still is annoying, and I do not wish to keep a file that serves no purpose, so is there any way to delete it from my computer? What advice can anyone here offer? Thank you very much.

That is a file used by the Windows updater service.

It can be deleted, but you must first use the security panel to give yourself permission.

When I failed to delete the file by right-clicking on it, I simply dragged it to the recycle bin, and that, amazingly, worked. I am not certain why that was any different, but I am glad that it succeeded.

I routinely install a Take Ownership (http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/) reghack on WinV/7/8/X platforms. It let's you do whatever you want with any files you want, regardless what Microsoft or the OS stubbornly prefers. The downside, of course, is that you can unintentionally change/delete/move something critical and break OS functionality (be careful when using Take Ownership on OS folder trees!) - but mpsigstub.exe (http://www.file.net/process/mpsigstub.exe.html) is a nonessential chunk of bloat which can be safely removed.

Install Take Ownership, right-click on the offending file to actually Take Ownership, then happily delete without the slightest peep of protest from Windows. A restart may be needed to terminate a protected process already running in memory.
