    Poor Performance from Windows 10 - High CPU usage from SVCHOST


    Evening Folks,

    I just recently installed Windows 10 on my Dell Inspiron Laptop and so far I am not impressed at all - in fact, I am very seriously debating one of two actions - re-install Windows 7 or switching to an entirely different OS.

    The reason for reverting to Windows 7/switching OS are as follows:
    1) Currently with an idle system (i.e. no applications running at all), an svchost process is using anywhere from 40 to 60% of my cpu. When I did a tasklist on this process the following processes are attached to this one pid: Appinfo, BITS, Browser, DsmSVC, IKEEXT, iphlpsvc, LanmanServer, lfsvc, ProfSvc, Schedule, SENS, ShellHWDetction, Themes, UserMananger, Winmgmt, wuauserv. My question is this - is it necessary for these processes to be run. If they are, then am I looking at only being able to use 50% of my processor (since this one pid is using the rest of it)?

    2) For a virus scanner - I am using McAffee and under Windows 7, it took my laptop 24 hours to scan 231 GB of data. Since I switched to Windows 10 (Same hardware, same memory, etc) it now takes my virus scanner over 48 hours to scan 231 GB of data.

    3) If I had not been poking around and trying to change my update settings, I would never have found out that Microsoft expects their users to update the windows of the other users (Microsoft calls it Dynamic Updates). Now this is all well and good if some one had said something since I would have loved to know about it sooner since I am on a metered service.

    4) Some of the programs that comes with Windows 10, I have no use for but yet I can not un-install them (Cortana come to mind).

    5) It appears that even though I have turned off "Live tiles" the tile continue to update from the net (again - it would have been nice to know since I am on a metered service).

    If anyone knows how to work around these problems - I would greatly appreciate it other wise the only option that I know of is to revert back to Windows 7 or switch to a new OS.

    Thank you
    DHarvey

    Something is not right with your installation. For comparison, with my idle system Task Manager shows 0% CPU use and 0% disk use for most of the time. Over a period of 1-2 mins it will jump to 50% for a few seconds on a number of occasions as it completes some task or other but then drops down again.

    How did you install W10? Was it an upgrade via the Windows Update service or via an installation disk? Was it a clean install or did you choose to keep all your files and programs. I'm guessing it was the windows update route which has proved to be troublesome for some users.

    As you are already thinking of a re-installation I would suggest you first try a clean install of W10. If you get it working correctly on your system it will be worth it.

    Make sure you get the correct version/edition of W10 as an ISO download from the MS Tech Bench (this will make sure you get the latest build and avoid further updates) to match your original W7 version and proceed to install, skipping any activation steps as this will happen automatically once you are finished.

    There are tutorials and many threads that run through this process for you on this site.

    Hi, I have exactly the same issue with my Dell Precision. Upgraded from W7 to W10 and I have an svchost using 10% cpu constantly.
    I've done a screenshot from Process Explorer
    Thanks

    Hello Phil,

    I offer the same advice to you as I gave to @DHarvey3

    The clean install often solves these problems better than trying to find the route cause due to the complex interactions of the old W7 system with the new W10. I realise for many people it seems a hassle to reinstall all the software and to re-load all your personal files but it is worth the effort. In the end you often find that you do not need everything you had installed and by only putting back the programs you regularly use and ignoring a lot of the bloatware that comes pre-installed you have a much better system.

    Thanks for the reply philc43. I had solved my problem by disabling some of the services that I did not need but it seems like the actual problem was with Windows Updater being hung and constantly trying to update.

    I guess one of the biggest complaint that I have with Windows 10 (and by extension windows 8) is that the OS is designed for a Tablet/Windows Phone) and it includes so many services that are not on a desktop/laptop pc (i.e. touchscreen, swiping the screen to access functions, and Cortana - which by the way can not be disabled). It seems like every time Microsoft comes out with a new version of Windows, they add so much stuff that I will never need - currently the number of background processes/background services on my machine right now is topping at 85 programs )

    Anyways - thanks you again for your reply and I will try this OS for a while but in the end, I have a feeling that I will be switching OS.
