Windows Update Using 600MB of RAM RRS feed

  • Question

  • I'm trying to troubleshoot a computer (not mine). It's running extremely slowly. Often it's at 99 percent memory usage.

    The process in question is svchost.exe (netsvcs). Specifically; the WuAuServ (Windows Update) service. I've seen it creep up to almost 1GB (it passed 1000MB, but not quite 1024MB). Normally it's running at around 300-600MB for the one process, and the computer is sloooow.

    I've checked Windows Update, and all of the Important and Recommended Updates have been installed. I checked the latest Internet Explorer update on the Microsoft Download Center, and that's been installed.

    (In order to determine that the WuAuServ process was the one at fault, I gave it its own svchost.exe process with just that one service running, using sc config WuAuServ type= own. That's the one that pushes the memory up.)

    What should I do now?

    EDIT: The computer is running 64-bit Windows 7 with 2GB of RAM.

    Once windows load, try the updates again.

  • I clean booted it and checked Windows Updates again, but there weren't any extra ones there.

    I set Windows Update to just run every week (rather than every day), and hopefully that will make the computer usable. (Even on the days when it does check for updates, the memory drops back down after a while and the computer runs fast again.)

  • Nothing great.

    There is no avialble updates. System up to date. 
    The problem is that the system is in normal daily check for updates using 900+ MB of ram, and peak up to 1.6 GB.
    Once the wuauserv finishes checking for updates,  the system returns to its normal state.
    On computers with 4gb Ram check for updates takes 3-10 minutes and not very obvious for user
    On computers with 2gb Ram check for updates takes 20+ minutes and make PC totally unsuitable for work. Even  mouse does not move properly on the screen during the check for updates. I repeat, check for updates, not installing, not downloading, just scan for new one.
