**Original Title:**What is Windows update 976902, aka the "Black Hole Update"?
On Tuesday, October 26th, a Windows update listed "Important" was issued along with three other updates. It was at least for Windows 7 x64, but probably other Win versions, too. The update stuck out because of its description, something about being uninstallable and required for future updates, but I can't remember it all anymore. The KB article link led to a 404, hence the name it has been given various places around the Internet: "The Black Hole Update." I believe the size of the update was >10 and <11 MB.
Speculation raged as to what the update did.
- Some older posts on various sites related it to installing Win7 SP1 Beta.
- The folks running a site called techarp were claiming that 976902 installed a heuristic scanner to the machine that turned on whenever the machine went idle, and searched all attached storage devices for "terrorism-related" information, then alerting "somebody" over the Internet.
- Some posters thought Microsoft had been hacked, and the update was really some kind of malicious third-party code being sent out to infect all Windows machines.
- But most rational people agreed that 976902 was just some WGA-style thingy.
Even though my Windows copy is genuine, I opted not to install it yet, to wait until more information was available.
That was yesterday. Today, 976902 is gone. It is not in my recently installed updates, it is not waiting to be installed on my taskbar like it was yesterday, it isn't waiting silently inside windows update, it isn't a hidden update. It's gone. And I'd like to know what it is and where it's gone to.
Microsoft...?
