    What I noticed in System Configuration (post #8) is everything is being started at boot except the lawn mower and the neighbors washing machine.

    Also AVG and Zone Alarm are both being used and started at boot in Startup and Services.

    I would recommend removing everything AVG and Zone Alarm using their online removal tool.

    For testing install MSE
    Microsoft Security Essentials - Microsoft Windows

    Then do a Clean Startup and see how things work. This little tutorial by Brink will help.

    Suggest taking a look at memory usage by:

    C:\Windows\SoftwareDistribution\DataStore\DataStore.edb

    Using RAMMap

    On the "File Summary" tab sort by "Active" highest at the top and if anything shows up as using a lot of memory

    Hello CG

    "Important Internet Protocol version 6 (IPv6) is a mandatory part of Windows Vista and later versions. We do not recommend that you disable IPv6 or its components, or some Windows components may not function."

    After all the actions I took yesterday without result I don't want to remove IPv6 in light of that warning.
    Thanks anyway. And yes, I also sense it is an update issue.

    Hello Layback Bear ... don't know what yr seeing but the start up is not heavy as you suggest ...see sc.shot. Also your suggestion of MSE is not satisfactory. I tried MSE and had to get MS Technicians to work on the computer as MSE was causing awful conflicts with downloads.
    I will read the tutorial mentioned.
    _________________________

    Hello Callender, although not clear to me yet I will try to follow yr recommendation and report back after.

    Results:
    1. Performed Troubleshoot Application Conflicts by Performing a Clean Startup


    2. Installed RAMMAP and while the list is too long to show more than a small window on I can't see anything like the numbers showing in the other thread (#post3128740) .

    3. Have turned off Win Updates. (Win7 Pro came out years ago ... if it's not up to date yet it never will be and it is more than enough for my purposes)

    LaybackBear - I've had some very negative feed-back on MSE from folk in the business so would suggest you check it out further. I'm told that it's not actually made by Microsoft. I liked it at first as it's light and was recommended here on the Forum but it caused enormous problems and had to be removed.

    Thanks for all your imput ... this is quite a learning experience.

    Something has helped as the CPU usage has fallen back down to normal levels and the laptop isn't heating up like it was.

    If you turned off Windows Updates you won't see the problem in RAMMap.

    That would be disabling Windows Updates. If you want to test - re-enable then run an update check and watch RAM usage.

    +1
    Your earlier snapshot showed winupdate service taking something like 45% CPU. Turning it off will drop CPU usage

    re: ipv6
    I should finish my thought. You don't need to turn off ipv6 and keep it off. Rather, you can just disable it for 24 hours to see if that affects winupdate service eating the CPU. ipv6 in Win 7 only affects HomeGroup and Remote Access services. I've seen ipv6 cause problems in the past. You can try disabling it for 24 hours to see if its suspect in your case as well.

    In addition:
    > If you choose to disable WinUpdate service, you can still turn it back once a week (like on Wednesdays). See if it still collects and applies the weekly MS updates
    > I've never used them, but there are also some offline Windows update tools you might choose to look at

    /* EDIT */
    Also, check if there;s a firmware update for your router

    Callender, I completed the RAMMap first ... prior to turning off updates which was the last thing I did.

    ComputerGeek, thanks. Just now I need to rest from this material as there are other tasks waiting and learning so much about technical matters I know so little about is a little exhausting. So what I'll do is retain the link to this thread and after a break return and check the effect of ipv6 and also the update tools.

    nithig - Absolutely. Not at all a problem.

    It's your machine and always your choice if, what and when you want to do something (and at your convenience)

    Happy Computing! :)

    Update:-
    Ran Avira scan, Malwarebytes and the house call from Trend Micro so assume no infections.

    ran the IPv6 removal suggested above

    unfortunately the well behaved system didn't last long and now the sheer instability at rest is so very strange as I've never experienced anything like this before.
    Picture speaks a 1000 words so here's a sc. shot of what's happening.

    Having more than one anti virus program on one computer at one time is a NO NO. That is one thing that I meant.

    On Startups and Non Microsoft services this is what I mean.
    These are from one of my system. Of course it's your computer so you can and should do as you see fit.
