Windows 10 extremely slow after updating to 1909

I have been using a PC with 800 M Hz AMD Phennom II processor and 8 GB RAM running 64-bit Windows 10 for several years. It has been running great until recently it became extremely slow after Windows update since November.  I noticed that the CPU and Memory usage changed from about 50% to close to 100%. The performance resumed after I restored the system to the earlier version. Today was the 3rd time I did this and I checked the current stable version is 1903, so I guess the problem was caused by the new update 1909. I am afraid it will become slow again after the automatic update. 

Please advise if there is a way to allow me continue to use this computer. 

Thanks!

Hello,

Please try these suggestions:

Run System File Checker scan:

  1. Search for 'command prompt' using Cortana or Windows Search.
  2. From results, right click on Command Prompt and select Run as administrator.
  3. Type sfc /scannow command and press Enter key.
  4. Let the command complete and then reboot the machine.

If that doesn't works, try these steps:

  1. Search for 'windows powershell' using Cortana or Windows Search.
  2. From results, choose Windows PowerShell and select Run as administrator.
  3. Then type/paste following and press Enter key:

Repair-WindowsImage -Online -RestoreHealth

  1. Let the command complete, restart your system then.

If problem continues, perform clean boot and remove third-party programs slowing down your system:

Also, try updating to Version 2004 or latest version and see if it helps.

Hope this helps!

    I can confirm that if you install all the Windows updates, including the 1909 one which some people seem to think is the cause of the issue, that it fixes the issue.

    I think the issue was already present before 1909 and that update seems to fix it.

    We had machines on 1803, and those were also affected. After installing the Feature Update to Windows 10, version 1909, it immediately solved our problems.

    We ran through all the available updates today on a select few of our 50 machines and all those that we installed all available updates on, after the reboot they seemed back to normal.

    I did a clean install of Windows 10 1909 and added the updates which brought the version to 18363.657 and I still have the severe lag problem you are all speaking of.  I am running a AMD FX-8350 CPU, 16 GB DDR3 MEM, and a Samsung 500GB SSD.  When I was running Windows 10 1903 with the same CPU, MEM, and SSD I experienced little if any lag.  This has to be a problem with something that Microsoft messed up in the 1909 update.  This is not a hardware problem.

    Exactly same, 1903 is good, but 1909 has lag problem.

    I would like to state we started seeing this happening about 2 weeks ago in our work environment.

    I run our network with over 50 machines, and we now have at least half of them all running at 100% CPU usage, and system interrupts seems to be taking all the resource, which suggests a driver issue. I suspect the update probably caused an issue with one of the drivers. Our desktops and laptops all comprise of Dell hardware, and some Lenovo laptops, so maybe it's something common with the hardware. I notice at least one other person here had a Dell laptop, but someone else had a Sony laptop so maybe it's some hardware common with all of those, which the update is conflicting with.

    We did nothing other than allow windows updates to install automatically, and our machines range in age between 3 years old to 4 months old and it's affecting pretty much the whole range of those. It's not isolated to old hardware at all.

    If Microsoft want to contact me directly for bench marking or QA testing i'd be happy to give them access to some freshly built machines which have the issue and they can test all day on those. 

    All I know is this needs fixing because it's clearly an issue affecting specific hardware with the recent update, so some people are fine and think we're all banging on at Microsoft for no reason, but those who are affected essentially have an unusable machine, and given that it's affecting our business i think that it's only a matter of time until some larger corporations start chasing Microsoft for compensation.

    Don't let us down Microsoft.
