Found solution to this happened when I was updating Windows 7.
It hangs if you do not have Internet Explorer 11 installed.
Its supposed to install IE11 but mine never would, it would say to restart, but no IE11.
Of course first be sure your NOT updating with the built in one, by going to Control Panel, Windows Update, and Click on Change how I get updates, and set it to NEVER.
The solution for me was to get the Standalone IE11 direct from Microsoft.
Run it and it puts in the essential stuff and installs. Then restart windows. After that it now has IE11.

So I did this, rebooted, ran IE to check, then relaunched the Update program.
Then it goes to the ID check but did not freeze this time, in fact only took about 30 minutes, but it
went past it and now it is installing all the rest.
I do not use the autoreboot feature, and incidentally I did initially and that failed, while it seemed to work but did not.
Now I see it is installing 128 updates. But then I did already have SP1 version of Windows 7 so that took away some of them.
And Ican say my computer is SLOW. It is 2.5gn ram, and old single core Athlon 64. I can go to 4gb but did not have those laying around, so only have 1GBX2 and 512mbX2 sticks installed.
Once you get all these updates, you wont experience the 100% CPU hogging. WSUS uses almost no CPU hogging, so it is just worth it to use it on older systems period.
