my trusty acer laptop is being weird. i can hear it running harder than usual and noticed that with no programs open at all it's running at 93% capacity!
something called xuidow.exe is demanding all this energy.
Can you close the process? Does that help? If it's starting when you boot up, you could go into msconfig and stop the process from running then. If that's too difficult because the PC is too slow, boot up in safe mode, run msconfig and try to disable the process from there.
I don't like the sound of xuidow. It's not something well known to the intranet and it probably shouldn't be there if you don't know what it is.
I would look in the registry (regedit) under WKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion\Run and also RunOnce, and in the start menu->All Programs->startup and see if you can figure out where it is running from, and possibly where it came from.
