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'm glad it worked for you. It's lovely to have the luxury of both time and salary to get it working. To say that the ones who having problems are at fault is ludicrous. We have no control of when and how the updates are done and to expect us to troubleshoot the problem is basically unpaid and slave labour.

    Shame on Microsoft.

    hi there:

    1903 is like 1909. So, 1909 didn't cause your issue. I have been using 1909 since it came out and found no issues like yours. Did you have SSD for your device? If not, that is one reason why your Windows 10 is slow. You can install SSD and try it out. Maybe the processor is causing the issue too. Slow processor.

    Thanks for your reply. The PC has an SSD and a HHD for several years. The processor is slow but it has been running well enough for my needs until recent updates.

    Hi,

    Thank you for writing to Microsoft Community Forums.

    We understand your concern, as the PC became slow after the PC upgraded to Windows 10 1909. We appreciate your effort in providing us the detailed information on the issue.

    Meanwhile, put the PC in Clean Boot and see if you still have the performance issue. Refer the article How to perform a clean boot in Windows. A ‘clean boot’ starts Windows with a minimal set of drivers and startup programs. If the lag in performance does not reoccur in Clean Boot then please refer the section How to determine what is causing the problem after you do a clean bootto determine the root cause of the issue.

    Note:After you finish troubleshooting, follow the sectionReset the computer to start normally after clean boot troubleshooting to reset the computer to start normally.

    Let us know how it goes.
