Windows 10: CPU always at 100%; multiple copies of programs

    CPU always at 100%; multiple copies of programs


    I have several issues going on and wanted to see if anyone has an idea of what could be going on. I'm technically unsavvy so unsure if I have malware, or when things are just normal, etc. I had a cyberstalking ex a few years ago so am a bit paranoid at times.

    Firstly, when I hit ctrl alt del (which I have to do often cause things run slowly and if I open 3 or 4 apps inevitably things "stop responding") I see that CPU is always 100%. My laptop isn't even halfway full and I didn't reformat it, though I do use Veracrypt (but not for full-disk encryption, as that option is greyed out).

    There are also multiple examples of a program running-for example, there will be dropbox.exe 5 times though there are only 2 users for the computer.

    There are also countless svchosts.exe (over 50). Things keep popping up when I end a task or have it set to manual, like Cortana (even though I've disabled it in settings) and when I end it it keeps immediately popping back up 4 times over! The only time I ended something and it actually turned my computer off and gave me that scannable bar code to show an error was when I ended "remote procedure call" (I know I shouldn't end programs when I'm not sure of what they are, but I always end things with words like "remote," "telemetry" and "workstation" though they come back anyway.)

    I often have to force close things-I had every app closed I could think of but couldn't delete a simple file because it "was open in another program."

    Finally, even though my system is for Windows 64, it seems that when I download apps for Windows, it's always the 32 version. If it's supposed to be automatic, why are programs like Dropbox and most other apps using the 32 version even though I have a newer machine?

    Thanks-if anyone has answers to those questions individually or can see a larger pattern that could be contributing to my problems I'd be very grateful. I have Avast and malwarebytes installed (there are always like 7 instances of them open, 32-bit version of course) and use CCLEANER and nothing shows up but my computer is almost unusably slow!

    Hi,

    Having more than one antivirus running on your system, leads to poor performance. Windows 10 ships with it's own antimalware solution (Defender) and it do the job.

    First, I would suggest to uninstall Avast and Malwarebyte, then start scanning your system for malware using Windows Defender.

    That, at least, I can assure you is normal. I've just counted 72 on mine.

    Starting with the Creators Update (1703) where previously groups of related processes were run under one svchost, now each gets it's own svchost. There aren't actually any more processes running, it just look like more because you can now see them listed individually.

    Microsoft said:
    Beginning with Windows 10 Creators Update (version 1703), services that were previously grouped will instead be separated - each will run in its own SvcHost process. This change is automatic for systems with more than 3.5 GB of RAM running the Client Desktop SKU. On systems with 3.5 GB or less RAM, we'll continue to group services into a shared SvcHost process.
    Benefits of this design change include:

    • Increased reliability by insulating critical network services from the failure of another non-network service in the host...


    ...Instance counts can typically range from approximately 17-21 for grouped services, and 67-74 for separated services.

    So you see, our large number of svchosts is what Microsoft say we should expect to see. In fact, your 50+ is a little on the low side :)

    For Dropbox, it's because they don't make a 64-bit version. 32-bit apps run fine on 64-bit Windows, and unless an app needs the huge address space that 64-bits allows (eg. enormous Excel spreadsheets) there's no pressing commercial reason to develop both a 32 and 64 bit version. Many other apps will only have a 32-bit version.

    At the moment there is not 64bit for windows...

    Thanks for the responses everyone. I was thinking of uninstalling Avast, as that is one thing that shows up in multiple instances. Has anyone ever seen that, 100% CPU, column in red?

    That's good to know svshost.exe, I just wish I knew what was what since there are multiple pids rapidly changing all over the place.

    And thanks about Dropbox, when I looked in my programs and programs (x86) folders, it looks like there are some of the same programs in each. Why would it download two copies of the same program?

    I think I will try to post a screenshot of my CPU usage screen. I had previously never seen it go much above 50%, let alone be parked at 100.

    Don't use Avast so can't comment, others may be able to help there...

    Just click on the top of the PID column to sort the list by PID (works for all the columns).

    ...when I looked in my programs and programs (x86) folders, it looks like there are some of the same programs in each. Why would it download two copies of the same program?
    Not sure, but they must think it makes sense. Even Microsoft do that, look for Internet Explorer, Microsoft Silverlight...

    I think I will try to post a screenshot of my CPU usage screen. I had previously never seen it go much above 50%, let alone be parked at 100.
    Task Manager's Details tab and Processes tab, sorted in descending order of CPU would be useful too.

    I often see my cpu permanently at 100%, but then I regularly do heavy-duty video processing in the background, so I know the reason why :)

    As a last resort plus the fact you have a ex that is a stalker......I would do a factory reset and start from scratch....like it was brand new.

    You can actually use MBAM and Windows Defender together. But I'll suggest that you only keep Defender running in the background.
