What's This?

[Licker4U]

I just noticed this morning a file on my hard drive that's never been there before. The filename is msxml4-KB927978-enu.log. I'm thinking it's a Windows Update that happened automatically as I signed off last night. Is it safe to delete it? I'll only put a short bit of what I found in the file:
