    KB5001391 update fixes Windows 10 high CPU usage, Start menu issues


    Ahead of Windows 10’s May 2021 Update launch, Microsoft is ironing out the remaining bugs in the supported versions of the operating system.

    After applying recent cumulative updates, some users started seeing high CPU usage, which is caused by the system process. Users have been complaining on Feedback Hub about how their PCs suffer from extremely high CPU usage, which affects the performance of the entire machine as a result.

    Windows 10 KB5001391 update, which was published recently for version 20H2 and 2004, has brought a number of important fixes. It appears it has also introduced a fix for a high usage bug, but the origin of the problem remains unclear.

    The problem appears to be a race condition where two or more processes affected the performance of the system unexpectedly. When the bug is experienced, a sharp spike in CPU usage is noticed and deadlocks occur.

    KB5001391 update seems to have addressed this race condition.

    Windows update fixes broken Start Menu


    In 2020, Microsoft showed off its theme-aware Start Menu with a streamlined design that removes solid colour backplates. For some users, Windows 10 version 20H2 broke live tiles and users reported blank tiles after updating to the newer version of the OS.

    KB5001391 has addressed an issue that causes blank tiles to appear on the Start Menu with the following names:

    • ms-resource:AppName
    • ms-resource:appDisplayName

    The bug affected both first and third-party applications.

    These blank tiles appear for the installed apps after users apply the monthly cumulative updates. Although the live tiles are automatically restored after approximately 15 minutes, the problem is still annoying as it kills the basic functionality of live tiles and it was flagged by a lot of users on Feedback Hub.

    This optional patch addresses the problem and prevents these blank tiles from appearing on the Start menu.

    KB5001391 update fixes Windows 10 high CPU usage, Start menu issues Start-menu-issues.jpg In our tests, we observed that the issue has been fixed and tiles are no longer blank.

    The patch is currently available to all users using version 20H2 and version 2004 of the operating system. If you want to test out the fix, you can do so now via Windows Update > Optional update and you don’t have to join the Windows Insider program.

    To download and apply the hotfix, check for updates in the Settings app and click on the “Download and install” button beneath the “optional updates” section.

    It’s important to remember that this is a preview cumulative update and users should be prepared for unexpected issues before proceeding.

    Alternatively, you can wait for the May 2021 Patch Tuesday update, which is likely to be more stable and is currently scheduled to launch on May 11.

    CPU high usage at start up

    Hi Phoe. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

    1) See these general fixes for high CPU usage:

    https://www.kapilarya.com/fix-windows-10-high-c...

    https://www.makeuseof.com/tag/fix-high-cpu-usag...

    2) Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed
    in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

    Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

    3) Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

    http://answers.microsoft.com/en-us/windows/wiki...


    Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue
    with the other steps to go over your install most thoroughly.

    4) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the
    latest version.

    I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
