2 machines - both Dell with i7-8650U and i5-8350U (integrated Intel GPU) auto updated via the MSoft website a while back to 22H2 - no problems.
My Lenovo using an i5-11400T (also integrated GPU) was eventually offered the 22H2 update and I took it. The PC went into ultra slow mode plus no right click ‘run as administrator’ option. Apparently this was a problem in some cases when 22H2 was first released but fixed by MSoft a few weeks later.
The web though is still littered with complaints from folks that are having issues of various descriptions with this update. Many suggestions about disable this and disable that etc but I was under the impression that the update would only be offered on a selective basis once MSoft was confident the machine would be fully compatible for the update - obviously wrong in that area.
Does anyone have any idea as to why this seems to affect (hopefully) a minority of Win11 users as I’m confused.
All my machines run Windows Defender plus Malwarebytes. In the meantime I’ve rolled back to 21H2.
Both my other machines - Dells are running 22H2 with Open Shell and EP with zero problems. Took the plunge again with my main rig a Lenovo and allowed the thing to update to 22H2 as I'd gone back to 21H2 after the slowdown. Removed OS and EP before doing so. Reinstalled OS and EP after update and mouse right click flaky - sometimes it works and other times a no go. Tried a different BT mouse and an old corded one I had sitting idle - same result - flaky.
So rolled the Lenovo back to 21H2 and everything fine. In my case it would appear to be machine dependent but all go figure me time of this.
I had recently installed Windows 11 on a single core without Hyperthreading Intel Celeron 900 2.2GHz with just 2GB RAM. It was VERY slow but still usable for office work and downloading stuff. You could also browse the internet with a lot of patience. That is without any other application open, if I dared open a couple of applications I had to wait longer. It was a "single-task" system, multitasking was to be avoided.
Back to OPs question, I would first search for "Core Isolation" anf make sure Memory Integration is DISABLED. If enabled poses a severe performance penalty. This is only needed if you use virtual machines. Next thing is to check which applications load at startup and consume your resources. Right-click on the start button and select Task Manager. Click bottom left to show more options and go to Startup tab. Disable anything not necessary, such as starting Edge and Chrome, Google Update (you can update it manually any time) and others. Next thing I would check for viruses/malware with Superantispyware or Malwarebytes Antimalware. Update their database and do a complete system scan. Remove all findings and restart. If you find too many I would repeat the scan with a second utility, just in case the first one missed some. I would then do a full scan with Windows Defender or any other antivirus you have installed. Do these and post back if you still have any issue.
PS: Make sure you have updated your graphics drivers. If for some reason instead of your actual hardware Microsoft Basic Display Adapter is installed, it will slow down your computer as there is zero hardware acceleration, all visuals are rendered by the CPU.

Thanks for replying and my apologies as I managed to get it sorted from this thread. No idea why changing the theme and reverting back to my preferences should fix it but it worked.
Again apologies as I should have posted the solution on this thread - remiss of me.
