I'm on a dialup connection with one phone line so I have to have turn windows automatic updates off, but I update manually. If I leave automatic updates on, it will start downloading updates at inconvenient times (like when I only intend to be online for 5 minutes to check my email and my wife needs to use the phone) and then I have to stop the updates.

So, in the past two weeks svchost.exe (located in c:\windows\system32) has been repeatedly trying to access windows update. These are some examples of what it's trying to connect to in my firewall logs:
windowsupdate.microsoft.com (
au.download.windowsupdate.com (
download.microsoft.com (
download.windowsupdate.com (

The thing is, until two weeks ago, svchost.exe rarely tried to access Microsoft updates. In fact, looking over the past six months of my firewall logs, svchost.exe has not tried to contact Microsoft updates at all. And during the past week wualct.exe has been running a lot. I sometimes see the little update icon in the system tray. I haven't seen that there in over 2 years.

Can anyone explain why svchost.exe and wuauclt.exe (located in c:\windows\system32) have been trying to update so much in the past two weeks when they rarely tried before? It makes me wonder if something isn't working right or if I have an infected computer. I ran several antivirus and antispyware scans and found nothing. I don't think my computer is infected. But what I'm seeing doesn't make sense.

If this activity is normal then I'll accept that. But at least tell me why there's been more activity in the last two weeks than in the last three years.

You may have automatic time updates turned on. This runs as a svchost hosted process which periodically attempts to connect to an internet service to set your clock. You can turn that off by right clicking on the clock in your task bar, and select Adjust Date/Time, and click on the Internet Time tab.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I would suggest using this free application to re-register your Windows Update dll's: http://wiki.lunarsoft.net/wiki/Dial-a-fix#Standard_version
Also, try clearing the Software Distribution folder using this application also.

Then, check to ensure that you've got all the latest Windows Update software, and the Windows Updates that are required for your system.
In particular, check for Version 3 of the Windows Update software, and check for the KB927891 update

Both are available at this article: http://support.microsoft.com/kb/927891
