There are several common reasons why you can't update my Windows 10 to 11. Let's go through them systematically.
1. TPM 2.0 (Trusted Platform Module)
Most common issue - Windows 11 requires TPM 2.0
Check if enabled: Press Windows + R, type tpm.msc
May need to enable in BIOS/UEFI settings (often under Security settings)
2. Secure Boot
Must be enabled in UEFI/BIOS
Check: Press Windows + R, type msinfo32, look for "Secure Boot State"

Your processor might not be on Microsoft's supported list
Requires 8th Gen Intel or newer, or AMD Ryzen 2000 series or newer (with some exceptions)
If any of the above requirements does not meet, you can't update Windows 10 to Windows 11 as normal.
