After allowing WGA to install on my Samsung Q1, every time I enabled the wireless LAN, the svchost process would chew up 100% of my CPU. So, I had to uninstall WGA just to get things usable again. Disappointing because this means I cant use Microsoft Update. Since WGA clearly has serious flaws, I'm not going to even consider OGA, but this locks me out of even more. I can't afford to install OGA because there doesn't seem to be a
known uninstall path and I can't afford to wreck my machine. I'm disappointed that paying (non-pirate) users are being punished.
One of our testers here had the same issue with svchost whenever he went to Windows Update (no WGA Notifications yet installed on the test computer). http://support.microsoft.com/kb/932494/en-us was the resolution.
