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!

    This is still an issue even after the KB4532693 update. My pc ran buttery smooth prior to this so it has to be 1909. I have even did a fresh install and still has the same issues. Everything is slow. Start menu takes almost 30 seconds at times to even open... Keep in mind this is a fresh install with all the latest updates. Whoever said 1903 and 1909 are the same are full of it. Now since I did a fresh install I cannot roll back to 1903 which sucks. My god Microsoft can we have a update where it doesn't break half the operating system? How is it Linux can do an update and run smooth but a multi billion dollar company can't even do a single update without something breaking? Hire back your testing crew that you fired because everything seems to have gone to **** since you got rid of them.

    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.

    My Dell laptop was the problem.  HP was fine and so was my Acer desktop.

    I had the hard drive at 100% so it seems there are different drivers or whatever affected.  Anyway my solution was to buy the new laptop and now that I am home a $27 SSD drive cloned gives me 25 second boot and 1% disk useage at idle on the original.  File transfers are now fast, so that solved my original laptop problem but $700 later with the new laptop.  A retired systems guy doesn't need to spend $700 because of a Windows 10 update!!!!  :(

    I have a under  $100 Windows tablet with keyboard and mouse that was operating better than that laptop and it only has 1GB memory!(but cannot be updated to these W10 versions!)
