After processing the updates from yesterdays (4/9/2013) update Tuesday all of my machines now run Check Disc at every boot. Does anyone know which update is causing this so I can can it?

KB2823324 is causing the issue. We run all Dells, mostly Latitudes. I'm not sure its going to effect other machines, but I cant imagine why it wouldn't.

Looks like you aren't the only one. Being discussed here as well: http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/245c2696-59cb-4a05-94fe-ff763867f677

Yeah... I looked for an article but couldnt find one. So... I made a new one, but it's definitely KB2823324 that caused it.

Thanks, we were having this same problem at my office. All of us are uninstalling the update.

In our organization, only about half of the users are affected by this. If a person is not having any issues with the update installed, and you remove the update, then your computer starts to have the chkdsk problems.

me too. I'm getting it on about 8 client computers but have another 8 that are not doing it. I'm just so glad to see others are being told all their hard drives are dying after this update as i was getting concerned some malware had slipped through. I hope a patch comes to fix it.

Uninstalling this did not working for me. Is there any fix for this? We have about 5 pc doing this and client pc's is now also doing this. Had to block the update on WSUS.

It happens to lots of our customers too with Windows 7 pro machine. It does not relate to only one brand but multiple brands machine with Windows 7. Initially we never taught it was windows update problem until one customer told us the windows update created this problem. now we have a total of 86 PCs out of 5 customers were having this problem. Hope someone in Microsoft comes up a fix get this fix ASAP.
