I've come across a couple of PCs that appear to be suffering from this problem click here. (svchost process slowing the PC down). I haven't had the chance to try the updates, but I wondered how widespread the problem was. Has anyone else experienced it?
Thanks for your replies. I guess it's only a problem with certain types of hardware since most people don't seem to be suffering from it. I have a suspician that it occurred when I upgraded from Windows Update to Microsoft Update, but I can't be sure.
