Question How to downgrade Windows 10 21H2 to 21H1?

[TheFlash1300]

This is the Windows 10 version i have:

Edition Windows 10 Pro
Version 21H2
Installed on ‎5/‎22/‎2022
OS build 19044.1741
Experience Windows Feature Experience Pack 120.2212.4170.0

It turned out version 21H2 is not supported for my CPU, AMD A4-9120e. I want to downgrade to the version my laptop came with. I believe the version was 21H1, but I'm not sure. Anyway, i want to downgrade to 21H1, because, i think, it uses less CPU, and is less likely to damage my hardware. After all, 21H1 is tested and proven compatible for AMD A4-9120e, while 21H2 isn't tested for my CPU, and there is no way to know if there is a lack of compatibility that may damage my hardware.

So, can someone tell me how to downgrade to the previous version?

Clean install is only way back

21h2 replaced the image windows uses to install itself, so only way back is to clean install.

you might have fun finding the installer. Unless you have one for 21H1..

10 seconds on Google proves you wrong. The AMD A4-9120e IS supported. Just because your specific CPU isn't on the list the fact that the family is supported means that your CPU is supported as well. Besides, if you simply install the previous version it will be auto updated fairly soon anyway.

And again, you are looking for a "solution" to a "problem" that does not exist.

Just because your specific CPU is not listed does not mean it will instantly and automagically "damage my hardware "
It won't. Indeed, it can't.

And since this is merely a continuation of a previous thread, and specifically this comment from me...closing this.
