Windows 11 News

Microsoft is rolling out the KB5008353 Update for Windows 11. This is a preview update that addresses several problems that were reported by users.

KB5008353 Update for Windows 11 fixes File Explorer lag
In December 2021, many users reported poor SSD performance in Windows 11. The concerns were later acknowledged by Microsoft, and that it was investigating the cause. Shortly after this, Windows Update KB5008215 was released with a patch to resolve the bug, but feedback from users were divided on the matter.

But after today's update, users are claiming that KB5008353 seems to have actually fixed the issue. The change log for the update mentions that it addresses a performance regression issue that occurs when you enable the update sequence number (USN) journal.

I have only been using the computer for a few hours since installing the update, but I can already notice a marked improvement in File Explorer's responsiveness. The speed of the desktop right-click menu and Explorer's context menu have also been improved. This is with an m.2 SSD mind you, if you have an NVMe Solid State Drive, your computer should perform even better.

Your Microsoft Account

The Settings app has a new page in the Accounts category, it's called Your Microsoft Account, and has shortcuts to view your rewards, manage your payment options, order history, get account and billing help. This page is available for Windows 11 Home and Professional Editions.

Fixes in the KB5008353 Update

The update fixes an issue that was causing app icons to be displayed on the system tray, even if the apps weren't running. The taskbar's auto-hide reliability has been improved in multi-monitor setups. Devices should not stop working when connected to multiple displays. Icons will be displayed properly on the taskbar on secondary monitors.

The bug that was causing Windows 11 to render colors correctly on HDR displays has been patched. The responsiveness of the auto-brightness function has been improved for low light conditions. Hardware-accelerated Bluetooth audio devices will no longer cause the audio service to stop responding. The volume icon will no longer display the muted icon when the audio hasn't actually been muted. Battery percentages for connected Bluetooth devices should now indicate the proper level in the Settings app's Bluetooth and other devices page.

ARM64 devices will install applications properly and not stop responding while entering hibernation or waking up from it. The Input Method Editor (IME) will allow the input of strings. A problem related to Microsoft Intune and third-party mobile device management (MDM) tool that was causing VPN profiles to disappear has been patched. Devices with a Microsoft Account can now access the touch keyboard from the lock screen. Printer companion applications will be installed when a printer device driver is being installed. An issue that was causing the error “IRQL_NOT_LESS_OR_EQUAL” has been patched. T

The only known issue in the update is that the Microsoft Outlook desktop app will not display recent emails in the search results, if the data has been stored locally in PST or OST Files. If the program is set to use server search, the issue only affects the advanced search. The KB5008353 patch is a Cumulative Update, you will need to restart your computer to apply the changes in it.  For a full list of fixes, please refer to the official knowledge base article.

While I had not experienced major lags in the OS, the new update seems to have made the user experience snappier. I'll continue testing it with my regular usage and with games to see if there are any performance gains.

Have you installed the KB5008353 update, do you notice an improvement in the performance?

    no problems found with the KB5008353 update on my end – performance was about the same.
    good thing I don’t use certain Samsung M2 SSDs like the anonymous person above me

    I am uninstalling the update as now my write speed of my M.2 decreased from 3000mb to 800mb i can even post a screenshot of my test on Samsung magic and crystal disk.
    So no thank you will wait to install this update again after a while and test.

    This is one update that will not download and install on my machine which is set to run on unsupported hardware and I constantly get different error codes for this happening so I am just going to ignore it as I assume that Microsoft will stop support for my machine anytime hey want to.

      I’m not getting it either and it’s April!

    Eh, minimal difference.

    This update fixed my incredibly slow Explorer on Win11 – I wasn’t interested in SSD speeds, so didn’t check before/after. But Explorer is usable now…

    Windows 11 is a bloated disaster. The more legacy they remove, the more bloated features they add that is worse off than the old legacy parts. Its a sinking ship I want no part of in the future.

    Thanks Microsoft, for fixing what should have never been broken in the first place.

    Win 11 explorer is hot garbage. Like so many other things, power users must find a third party replacement if they haven’t already. Tablacus and Q-Dir are both good for power users and use the Win 10 context menu by default on Win 11.

    Power users need a whole suite of utilities to make Win 10-11 even remotely bearable.

    Its still laggy and slow compared to any other OS to date. Too many bloated web technology hooked into the shell. Install any version of Windows prior to 10 and you will learn what real performance is. Using Windows 8 and 7 feels like an upgrade. Moving through Windows 7 and 8 UI feels fast.

    Very sad how far Microsoft and Windows has fallen with 10 and 11.

    My sister’s laptop is stuck at 69% of installation. Here we go with the first issues! :[

      False alarm, after twenty minutes waiting it goes on again, now at 88%! :]

    Installed and working fine here! We are going for the right way, thanks @Ashwin! :]

    Does anyone here have a Brother or Canon inkjet printer who can confirm whether the printing issues have been resolved? It’s one of the main reasons why I’ve gone back to W10.

    I guess when you mentioned you have a M.2 SSD means you have a M.2 SATA SSD. NVMe SSDs can be M.2 also, among others.

    M.2 is the form factor standard. It refers to the size and the shape of the ssd that it can use.


    NVMe is the interface standard used to connect your SSD. The other older one would be SATA.

    You can have a M.2 NVMe SSD or a M.2 SATA SSD.

    Martin, please get your staff to read up and study a bit before posting articles. I’m not saying we need advanced in depth or anything since this is not that kind of website, but getting the basics wrong can lead to mistakes by your readers.

    What the HELL is going on??????? Microsoft released IMPROVEMENTS??????????????????!!!!!!!!!!
    Ok, these should have been in place 5 months ago, but still.
    I’m not impressed, I’m in total disbelief and shock. This is seeing Elvis alive, this is taking a picture of the Loch Ness monster. I can’t breathe, this is almost like when XP got SP1. I can now die in peace, knowing I witnessed something that will never ever happen again.

      I am in disbelief too with people like you, I bet you gonna complain with everything happen in your life, you going to complain about someone doing good deed and asking why not doing it one minute prior and so on…

      Yet another Beta release — it’s now not “when” but “if it will ever end”. Maybe with Win 12.3 (or a version of Linux)
