    Windows 10 very slow - sfc scannow results


    My computer just started running very slow - almost unusable. Ran a Kaspersky virus check - no problem. Ran a System File Check (results attached). Don't know how to read the Log - otherwise, I would have included it. Could someone tell me what steps I should take next? Thank you.

    Windows 10 Professional (x64), Version 1809, Build 17763.914

    You may have to run sfc /scannow up to three times to repair.

    Alternatively you could use DISM, steps 1-5

    Use DISM to Repair Windows 10 Image

    Failing that you may need and external source (Boot media) to run steps 6 or 7.


    Are you dual booting? There is a repair install and while there is no warning about dual boot systems I would ask Brink within the tutorial thread if there are any issues. I think I remember a long time ago you were dual booting.

    Repair Install Windows 10 with an In-place Upgrade

    I assume you have boot media for your current version. If you use boot media at a higher level, say 1909 and you are using 1903 the repair install will do an upgrade.

    As Caledon Ken commented the scannow corruption is often fixed running the dism commands.

    Consider an in place upgrade repair from 1809 to 1909.

    Uninstall Kaspersky using the applicable uninstall tool prior to the upgrade.
    Reinstall as needed after a successful upgrade.

    Thank you! I have a boot media (original Windows 10 CD). How do I get a boot thumb drive with the latest version of Windows 10 (1909) - and do you recommend this avenue? If you do, please tell me how to use this boot media to run dism. Thanks again. Oh, one more thing: If I reply to you, do the others that have replied to me also get my reply to you?

    Thank you. Yes, I am dual booting (you have a great memory). I use the default boot for my work - but never deleted the second boot - although it's useless because I could never repair the system files that were corrupt. I ended up starting from scratch with a reinstall. Problem is, I'm getting old and have forgotten the steps I need to go through to repair the newly corrupted system files - I need much help. At the moment, I'm running sfc /scannow several times to see if that fixes the problem.

    Thank you!!! OK, just finished running System File Checker 5 times. After the first run, my computer is running at normal speed - but there are still some corrupt files after the 5th run. So, I would like to try dism to fix the files - and do an inplace upgrade to vs. 1909 (if you folks agree that is the correct path). I need instructions on how to create a bootable thumb drive - then how to run dism. Not sure if an inplace upgrade would also fix the corrupt files. Need to get this done before I lose my speed again. Thank you for the guidance.

    I think all your steps are clear except #15.

    1. Another forum room?
    2. V2?
    3. BSOD - Posting Instructions (I don't get a BSOD). What is this for?

    Yes if SFC will correct it will correct within three runs.

    So I posted the DISM tutorial. Execute the commands, they should correct situation. They are straight forward.

    For In place repair / upgrade

    Here is the tutorial for creating USB

    Create Bootable USB Flash Drive to Install Windows 10

    Basically you follow the link to the Media creation tool. Download the tool and execute. Follow prompts

    At this point you can create a bootable 8GB USB thumb drive or download an ISO. If you go ISO place it on your desktop.


    Then to do the in place repair upgrade, enter UEFI / BIOS and disable secure boot, then ...

    With USB - plug it in, navigate to Setup and double click. Follow prompts. When you see the system will restart shortly pull USB thumbdrive

    With ISO - right click file, click mount. Navigate to Setup and double click.

    If you have a 16GB USB thumbdrive I use Media Creation tool to create USB key and then I rerun process and store the ISO on the same USB so I have both. I can copy ISO to a person desktop, mount and run setup.
