What is the Web Access Control Service (wacsvc.exe) for?
Can I safely disable it?

Because every once in a while, it goes crazy, and uses 99% CPU until it is restarted.

This is on a Windows 7 Home Premium 64-bit computer.

from google I found out, this services is Access Connections Main Service and belongs to the ThinkPad Access Connections suite. So lok at the Lenovo site for an update and lok into the documentation what this tool does.

Oh ThinkDisadvantage, how I loathe thee. – Feb 3 '13 at 7:00
I don't think so... This computer is an HP and does not have ThinkPad Access Connections suite installed. This service is a Windows service, but what is it for? – BenjiWiebe Feb 4 '13 at 14:32
this is not a Windows service. I don't have it ;) Run ProcessExplorer, look at the commandline of the tool, go to the folder and look at the file properties (Product and Company name). – magicandre1981 Feb 4 '13 at 19:24
@magicandre1981 It definitely is not part of ThinkPad Access Connections suite. See my post. – BenjiWiebe Feb 4 '13 at 22:42

Aha!! I finally figured it out. It is a component of the Internet filter we have installed ( I won't disable it, I guess. But it sure would be nice if it did not hog the CPU.
