Hell, Microsoft was fast! After December Patch day (12/19/2014) with KB 3004394 update disaster (see my articles Update KB3004394 breaks Root Certificate in Windows 7/ Windows Server 2008 R2 and Patchday: Windows Update error 800706F7) Microsoft finally has withdrawn this patch. Too many “collateral damages” has been observed (Windows Update has been broken, Defender doesn’t work anymore, Narrator and other assistive tools refuses to work and so on). My suggestion was to uninstall KB 3004394 (December-Update for das Windows Root-Certifikate) on Windows 7 and Windows Server 2008 R2.
Microsoft Update KB3024777 shall fix it
After login to my Windows 7 machine, I noticed this morning an Update KB3024777, just 29 KByte in size. So I decided to let it install and begun to do a Web search …
Well, I had pretty much time for my investigations, because installing Update KB3024777 required a reboot. And then I observed heavy Registry update activities along with heavy hard disc activities. Just before I accepted Update installation, I’ve tried to launch Narrator (this tool should also be affected by KB 3004394). Narrator doesn’t show up – until 5 minutes after Update install boot. Strange things must be happened.
