I have a 5 years old computer with an Intel I5-6600k CPU which is too old for upgrading to Windows 11. All other W11 requirements are met (TMP2.0 ...). I read that one can install and run W11 with this regedit entry:
Path: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
Name: AllowUpgradesWithUnsupportedTPMOrCPU
Type: REG_DWORD
Value: 1
It was said that the system might not run, and certain W11 update won't work. Has anybody tried it and can report on his experiences?
EDIT: I upgraded from W10Pro a month ago now and haven't had any problems so far. It works fine on: I5-6600k with 16 GB Ram and 500 GB M2-SSD. The performance is the same as with Windows 10.
