I needed to replace a couple PCs that had a single COM port with a PC that had multiple COM ports and was relatively small in size. I was also seeking a Windows 11 PC. This PC seemed to tick all the boxes but fell short when I brought it online as Windows 11 wouldn't activate. I tried running Windows Update because sometimes it needs to be updated first then tried activation but it still wouldn't activate. It also would not update to Windows 11 22H2, was stuck on version 21H2. When checking for TPM, Windows did not recognize one installed. After opening the case and inspecting the motherboard, there also is not a header for TPM so it is not possible to add.I give it 3 stars because it had all the things as listed in the description but Windows 11 will not activate or update.
