Like the title says I experienced a major drop in performance after using windows update to upgrade to windows 11. On a whim I decided to download the latest Windows 11 ISO and performed a clean install. Computer is snappy/fast again. Not sure why this would be, but wanted to see if anyone else has experienced this.

Perhaps the original Windows 11 upgrade was buggy or corrupted in some manner.

Next time you experience a performance drop look in Task Manager, Resource Monitor, or Process Explorer.

Process Explorer may need to be downloaded - Microsoft, free.

https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

Use the tools (one at a time) to determine what system resources are being used, to what extent ( % ), and what is using any given resource.

First look now while everything is snappy and fast. Print out some screenshots for reference/comparison purposes later on if necessary.

Take the screenshots right after initial boot when the system is stable, then a set while doing light work or browsing. Then a set while gaming.

Then, if the problem returns, you can compare the "now" to what was working before. May provide a clue or two.
