I have AMD FX(tm)-6300 Six-Core Processor can I upgrade my CPU to make it compatable with windows 11?

Processor AMD FX(tm)-6300 Six-Core Processor 3.50 GHz Installed RAM 12.0 GB Device ID 4A5A73FB-6C8C-4093-80C4-58355366A1EE Product ID 00330-80000-00000-AA346 System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display

As you said, the AMD FX(tm)-6300 Six-Core Processor is not in the list of Windows 11 supported AMD processors.

You should know that beside the CPU, you also require a motherboard that supports Trusted Platform Module (TPM) version 2.0, which is an integrated chip into the motherboard. If your motherboard does not have this chip, there is no point in upgrading the CPU.

Even if it's not enabled for you, some motherboards support TPM 2.0 but it's just not enabled. See Enable TPM 2.0 on your PC to check if yours is one of them.

If the motherboard does have TPM 2.0, you may upgrade the CPU to one that is on the above list. See also Windows 11 supported Intel processors.

If you finally need to replace both the motherboard and the CPU, it might be more economical to buy a new computer that is certified for Windows 11.
