Problems after installing Windows 10 21H2

Im sure most of you know that Microsoft forced users to install 21H2 this week on Windows update because i was still using 20H2 and unfortunately i was one of its victims. The update itself only took about 3-5 mins to install which to me its strange but anyways after the update my laptop started being unstable, at first i thought everything will be fine without doing a clean install because it was a small update like 21H1 i think but my laptop is running hotter in games even games like American Truck Simulator and at times when plugging in the AC Adapter my CPU will lock at 2.8GHz and i would have to put my laptop on standby and start it again to get it back to normal clock speeds. There are other issues im noticing as well but im not completely sure.

 

Anyone have these issues after the upgrade? I really dont want to reinstall windows but i will if have to.

Windows 10, version 21H2 is deployed as an enablement package if you are coming from Windows 10, version 2004.  It's not a full build upgrade like most prior "feature upgrades".  It is normal for it to only take a few minutes to install.

 

Very strange to me if it is causing issues like this.  It really has very few changes.  You can roll back to your previous version of Windows 10, though, by uninstalling the KB4562830 update package.

Yea it is strange.

 

I rolled back to 20H2 last night but the same problem still happens and i figured out the problem, It turns out to be a hardware issue with my battery, I recently purchased another 80WH battery this past week from Amazon after the last 2 80wh batteries i bought from 2 other sources were defective and this one charges way too fast with fast charging off like 60watts like i have it on and with fast charging on it would charge over 100watts which it way beyond normal and also it would throttle at times when playing games because of it, They're shipping me a replacement battery and should be here sometime this week. I'll try 21H2 again after that i think.
