Warning - KB3004394 corrupts system files

I was getting WGA problems with popups saying that my version of Windows wasn't authentic. (My Snipping Tool had stopped working too). I deleted the KB3004394 update and I have just checked my operating system and it is now being recognised as authentic, and the snipper works too. Thanks folks.

I understand that KB3004394 has been "pulled" by Microsoft. I haven't had any issues after new Update Patch was installed on my Wins 7-64 OS. All seems to be working just right at the moment. I assume that Microsoft will be issuing a FIX to correct this. I'll just have to continue to use my machine and see what happens if anything. Does anyone know about Microsoft releasing a FIX??? Hope to hear from you guys soon.....

I haven't had any problems either. Weird. I checked that the patch got installed successfully, it did. sfc scans without an issue, the magnifier works, the snipping tool works, can't find anything wrong here.

I just uninstalled it be on safe side. Can't see any difference either way but the update wasn't offered again as advised by others

Best always to uninstall a troublesome update if you can, rather than do a system restore which can leave a messy partial installation if you're unlucky.

I just went through my Windows Updates and i see that this KB3004394 was not installed on my machine. I usually get my Microsoft Updates Tuesday during the afternoon but this last Tuesday I checked for updates very early in the morning on my own and downloaded them. Maybe that's why it's not on my machine. Don't know why, just curious. Does anybody know???

I was also having problems with popups saying that my version of Windows wasn't authentic, following my Tuesday update. Chatted with a tech from M$, who, after streaming in, reset my authentication, and said it was fixed.... Rebooted, and immediately got another authentication popup... This morning, frustrated (naturally), I started researching, and found numerous similar complaints, all pointing to KB3004394... While reading through, and deciding on doing some abstract repairs, I noticed that I had received an Important Update notice from M$, KB3024777, to correct a flawed update... Imagine that !!!... Ran the update, ran MGADiag, and behold!!!... Problem fixed... And, BTW, M$ recommends NOT removing KB3004394 by "hand", as it could cause "unforeseen" problems. Best of luck to all.
