    Windows Update shows error 80070BC9, updates fails


    Hello, I got moms laptop for repair, and found one problem. I can't install 6 updates, one of them is that Windows 10 one. Windows update gives me error 80070BC9. I already tried sfc /scannow, even on boot, it threw "unfixable" errors on me too.
    Any help? (Windows 8.1)
    Thanks!

    P.S.: I tried to put CBS.log here, but I can't, don't know why.

    Please post the KB{number} list of the updates you are trying to install.
    Please upload the cbs.log file located at [windows partition]\windows\logs\cbs\ ,this log might have information about the problem + use this command
    Code:
    findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log > "%userprofiel%\Desktop\sfcdetails.txt"
    after sfc/scannow is finished.
    The sfcdetails.txt file shows what sfc could not fix.

    Try a 3rd party uploader like dropbox or something, it is most likely that the log file is too large.

    Here is CBS.log.CBS.log

    I tried to do that troubleshooting, it looked like it is working, but now it is downloading 7 updates for 11 hours right now and it is still on 0%.

    The CPU needs a driver update.
    Code:

    Well, I tried to download the update, but Windows said NO! This software cannot run on this computer. But it is exactly the driver what I need, so where is the problem?

    Did you try it via windows update?
    If so, try it via the manufacturer.

    Well, update went well at the end, found version for .NET 4.5, which I installed earlier on, but something is going on else.CBS.zip

    I noticed that I forgot to post, which updates I want to install. It is:

    The problem is the same.
    How many times have you tried sfc command, rebooted and tried sfc command again?
