Windows Update run 100% CPU
I've got an Acer laptop that I just noticed runs 100% CPU when I try to update Windows. It has an AMD TF-20 processor, 1.6GHz single core, and 3GB of RAM. Not a fire-breather, but it should be adequate for normal tasks, and indeed it runs very well aside from this problem. This is a new bare-metal install of Win 7 HP x32.
I tried disabling WUDFSVC.exe. Nothing. I reset registry permissions, ran an update repair routine in Safe Mode, reset services to their default settings. Nothing.
Even now, 10 minutes after installing the one small Important update that was available, SVHOST.exe (driving WU service) is still forcing the machine up to 100%, with little else going on.
This machine must go out tomorrow, and this is a maximum pain. I am considering turning off WU, but would love to find an better solution.
Addendum: After the requisite reboot, Trusted Installer bounced around from 50-90% for a minute or two, with nothing else going on, which is pretty normal, and now the machine is back to idling at 1-2% CPU, which is how I have it tuned. It's simply the update process that is out of control.
