I have just upgraded to Windows 10 Version H21H1 but the system has become extremely slow. When I click on a program icon on my desktop, it takes quite a while for the program to open. And even web pages take a while to open and at times do not respond at all. What could be the problem or do I roll back to the previous version?

    Same here as well as the later KB50044xx - they keep installing but together with KB5003637 they are the culprit...

    Hi Carlo : I have done a cleanboot as well as the Repair Upgrade as advised by you but to no avail. The system is just as slow as before. Programs take ages to launch and browsers (be it Edge, Firefox, Opera, Brave or Vivaldi) not only take a long time for pages to open but most of the time it says 'Not Responding'.

    This reply took over 45 minutes on the Vivaldi browser before submission of the post succeeded . Clearly something is not quite right with the operating system.

    It appears unlikely the problem could be due a virus as I have run Malwarebytes, Windows Defender and SuperAntiSpyware and no threats were detected. My computer is absolutely clean.

    In the circumstances, I am considering going back to the previous version of the operating system but is there anything else I can try first?

    Hi Carlo, Thanks for the response. As requested, attached is a screenshot but you will note that usage is very low. Even if all the tasks are terminated so that there are no apps running, Windows 10 is still very slow. Programs and web browsers take ages to open and most of time web pages simply do not respond.

    Would you suggest that I download a fresh Windows 10 ISO and re-install all over again? Or is there another solution?

    Same problem here, using Microsoft Laptop 3, was great until few days ago. even clicking on windows start takes time to load. my productivity has dropped by 80%.

    Something is haywire, the cpu and disk are idling, memory is only 50% but every action is 10 times slower.

    is there a fix or update.
