I noticed these “test updates” in Windows Update today (Patch Tuesday, which occurs on the second Tuesday of every month):
The updates are:
All three updates have the same description:
This update is a test update to validate Operating System servicing. After you install this item, you may have to restart your computer. This update is provided to you and licensed under the Windows 7 Prerelease License Terms.
According to Microsoft’s site, these are simply used to test updating in Windows 7 and, since they’re based on the same underlying operating system, Windows Server 2008 R2 Beta. If you’re interested in the technical details, click the links for each knowledgebase article above.
After installation, it does not appear these updates affected my system.
If you had any issues, I’d like to know! Lovin’ Windows 7!
