Issue

Not possible to upgrade Windows 10 on Dell Optiplex 9010 to Windows 11 due to an unsupported processor (Intel Core i5-3570 CPU) and lack of a TPM 2.0 chip.

Resolution

The issue was resolved by making a small registry change in order to bypass CPU and TPM requirements:

• Open Registry Editor (regedit.exe)
• Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
• Create a new DWORD type entry:
  • Name:  allowupgradeswithunsupportedtpmorcpu
  • Value: 1

On this particular PC, I also had to enable TPM v1.2 in the system BIOS
