Same here. Dell Laptop Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.21 GHz
Dutch Windows 11 version. Great Microsoft, the second PC i'm trying (first PC didn't have a supported CPU) and it doesn't work.... Going to look at it....

Syncing Time, checking system files, removing update-files doesn't work. Same error on my Dell XPS laptop.
Tried updating a Dell Vostro 14, CPU not supported, tried HP Envy (2016), CPU not supported....
Terrible... Why does the message about not supported CPU show up if the process has been running for about 15-30 minutes. Why not at the start? I'm going to see if I can edit the installer so that I can try to install it anyway. Unknown why these CPU's aren't supported...
Seems that MS 'forces' a lot of people to buy new hardware just because of this upgrade...

@rcurci2 Ok you follow these steps
1) go to system32\driverstore\filerepository to find the folder with the naughty drivers.
2) right click to show Security tab
3) click on Edit
4)then select EVERYONE
5) then, in the bottom part of the window, select the checkbox for full control.
6) Now try to delete or move the folder to somewhere else.
7) restart your computer
8)Now run the downloaded Windows 11 ISO setup. (allow it to update and everything)
After this step, the Windows 11 installed smoothly for me!

@mstrada If you read my original comment, you will know how to know the identity of the driver and the folder in which its located.
In short, you have to access a log file located in "$Windows.~BT\Sources\Panther". You will have to go to Windows explorer's view settings, to allow hidden items to be shown, in order to access this directory. Under this directory, you will have to open the file name setupact.log.
Now here is the slightly tricky part:
1) You will have to open the log file with notepad.
2) Wait for the note pad to completely load the log file, as it can be large in size. (In my case it was around 50MBs.
3) Now the relevant information regarding drivers that are causing Windows 11 installation to fail, are located at the bottom of the log file. In order to directly jump to the end, press the CTRL key and then press the END key.
4) Now you should start reading the log file from the bottom up. Keep reading every line for 5 to 10 minutes, until where you start to see Windows errors 0x80070002 -0x20007 alongside of some driver paths. In my case, the driver folder was something like System32\driverstore\filerepository\WDScamxAMD64\wdscam64.sys or something similar
5) now the moment I saw the line in the log that mentioned WDscam, I knew it had something to do with the Western digital and their crap software.
6) You dont necessarily need to know the origin of the driver, because your mission is to just delete the folder you just discovered in the log file.
7)Just go to the System32\driverstore\filerepository, and find the folder, and delete it.
8) Remember, you won't be able to delete the file easily as it is a system file. For that purpose, you can refer to my original comment, on how to gain full access to system folders.
9) Your windows 11 should now install easily.
10) if it fails with the same error, repeat the process, because there might be some other bad driver in conflict with Windows 11.

I Just received the same error:
We couldn't install Windows 11
We've set your PC back to the way it was right before you started installing Windows 11.
The installation failed in the SAFE_OS phase with an error during INSTALL_DRIVERS operation
The failing driver for me was: RealtekService.inf
Your solution worked for me,

@youaremine Same issue the log information is very helpful. I have a language conflict it seems, even after removing the second language (Greek). The error looks like this:
CAddCbsPackage::DoExecute: Failed to add package Add  package C:\$WINDOWS.~BT\DUImageSandbox\Microsoft-Windows-Printing-WFS-FoD-Package~31bf3856ad364e35~amd64~el-gr~.cab to C:\$WINDOWS.~BT\NewOS. Error: 0x80073713
I guess the second language throws the error even after removed. Any ideas how to resolve this?
also note that there is a smaller log file in the same directory with the errors alone:
