Here is Dell's list of systems tested for Win 11.  The 8300 is NOT included. TPM 2.0 isn't the only requirement.  8th gen Intel CPU is MINIMUM required. Dell computers tested for upgrade to Windows 11 | Dell US    
Windows 11, TPM and XPS desktops (June 2021) Hi, In the light of the requirement for TPM 2.0 as a standard for Windows 11, I would like to ask if there is a chart/list/ of which XPS models contain TPM 2.0?  I am specifically looking for info on the XPS8700 late 2013. It is not something I have ever remembered seeing in various BIOS configs. Am I right in presuming that if my XPS8700 does not have TPM2.0 , I can purchase and plug in a TPM module to the motherboard?  Thanks in advance
