Odd files found in an odd folder.

There was a folder in C: that I found and it held a few weird files. The folder name was 747739bb34bf4ece91f3c95277 and it had files called;
Windows6.0-KB956250-v6001-x64
Windows6.0-KB956250-v6001-x86
Windows6.1-KB958488-v6001-x64
Windows6.1-KB958488-v6001-x86
and they were all Windows Update Standalone Package files. My computer has only ever been on Windows 7. I'm wondering why they are there, and would they downgrade my OS if I opened them? (I'm not actually going to open them.)

Ah, thanks.

The Windows6.0 and Windows6.1 are version numbers. Version numbers in Windows are confusing and you shouldn't try to read too much into them. There are multiple standards involved.

Incidentally the version number for Windows 7 is 6.1. Some others:
Windows 2000 - 5.0
Windows XP - 5.1
Vista - 6.0
Windows 7 - 6.1
Windows 8 - 6.2

File versions in these system may or may not match these numbers.

Names like "Windows 7" are chosen by Microsoft marketing people long after the version numbers are assigned.
