    Updates KB4512508 & KB4506991 - performance problems ????


    These two updates were installed 8/13 for KB4512508 and 8/14 for KB4506991.


    Not date certain but after these two updates I have experienced performance problems. Specifically virtually everything I do -- typing, entering data, using any software programs [photo editing, Libre Office, etc.] my browsers, and more there is a time lag between the key stroke or action like minimize/maximi. The PC just seems to take a break and then catch up.


    I have tried some cleaners and nothing has helped.


    !) have others had this or similar issues?

    2) any suggestions to fix?


    Should I uninstall these two and re-install?


    Would it be better to go to a system restore point?


    Thank you!

    :)

    Hi, you might try downloading it (them) manually from the links posted in the article per update per build in the News section:
    Cumulative Update KB4512508 Windows 10 v1903 build 18362.295 - Aug. 13
    https://www.tenforums.com/windows-10-news/136266-cumulative-update-kb4506991-net-framework-3-5-4-8-windows-10-july-9-a.html


    Otherwise you could have a look at your Windows Update log. (Google if unsure)

    Also consider the Windows Update troubleshooter and

  3. Canceling an Update - KB4506991

    I have tried to permit the update of Windows 10 PRO on my wife's Dell XPS13 twice and each time start up files were corrupted requiring the complete re-installation of Windows - a very long and painful process! The 1093 update installed fine but then KB4506991
    comes along as, with 1093 they want the Net.Framework to update. It is KB4506991 causing the problem. For the 3rd time I now have the computer up and running and all programs re-installed. I don't dare let KB4506991 install again. I know I can delay all
    updates but I desire the update process continue - just don't want KB4506991 to crash my computer again! Any suggestions? I know it has been a HUGE complaint of Windows 10 users that we cannot control individual updates - wish Microsoft would listen!

    Updates KB4512508 & KB4506991 - performance problems ????

    Windows update failed (KB4506991 & KB4512508)


    My computer tries to install and update these files:
    KB4506991 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10, version 1903
    KB4512508 (OS-build 18362.295)

    Ï have tried pretty much everything of troubleshooiting I have read online. I have tried to download and install the files manually from Microsoft Update Catalog.

    But yet I get update failed, all the time. When my computer tries to install the new updates, when it restarts it somehow stops at 7%, and then I get told that the update failed. It seems that it wont go past 7%, hence why the download might be failing.

    Any help on this please? I am really frustrated since this is a brand new computer.. *Banghead
