What's a good GUI utility to apply patches on Windows?

Question

I'm looking for a good GUI patch utility for Windows - this is something that I'll be sending to someone who hasn't worked with patches much before, so ease of use is important. I know WinMerge can generate patches, but it can't apply them; does such a GUI utility exist for Windows?

PS - I considered posting this to superuser, but since diff/patch are primarily programming tools, I thought it would be better suited here. If there's consensus otherwise, I'll vote to migrate myself.

TortoiseMerge, which is found in TortoiseSVN, TortoiseCVS, or TortoiseGit will fit the bill. However, be warned that the full installation adds other right-click menu options by default, so the user may prefer to custom-install just the piece(s) they want.
