Would you mind pointing me to where you are seeing models fo Dells and Toshiba's impacted?

I'm also having problems on my Acer laptop running Windows 7 after a Windows update last week.

Symptoms

Normal start-up to Windows 7. Then hard drive is going 100% all of the time. CPU activity minimal. Computer slows down to a crawl. Programs won't start - timing out - or very very slow.

Ctrl+Alt+Del returned message - The log on process was unable to display security and log options when CTRL+ALT+DEL was pressed. If Operating system does not respond pres ESC or shut down via power switch."

Having to shut down via power switch or Windows has to force it as programs won't close.

Actions Taken

System restore via safe mode (several times!) . Then start up repair required. Computer then works normally. Went to Windows Update to manually control updates but that doesn't seem to work. If I deselect all the updates - press Ok then close and then re-open Windows Update they have all been reselected again. Tried Windows Update online repair which didn't seem to make much difference with on normal shutdown the message installing updates appeared on the monitor.

Looking at the event viewer some updates installed correctly at the first attempt but having been removed on the system restore don't seem to have loaded successfully again.

The post you replied to contains a partial list of the symptoms you can see with KB2862330 depending on the exact version of your Operating System, your USB hardware and your USB driver software.

Certain models of Dell and Toshiba computers are reportedly "bricked". However there are reports of people booting from recovery media and removing the bad patch with a manual batch file.

Others report USB devices stop working or BSOD when using USB devices. Some have connected PS2 keyboard and mouse to get into their system to remove KB2862330 and any linked USB-related updates.

The action you take depends on whether KB2862330 installed and then keeps wanting to install again, or whether it tries to install and either hangs or fails, or whether it installed and made your computer unstable or unusable.

Whatever you do, resist the temptatation to run Microsoft System Restore unless advised so by a Mcirosoft Technician.

Suggest you open a new thread mentioning KB2862330, your Operating System version, your symptoms and the make and model of your computer.
