By now you\u2019ve heard about the kerfuffle surrounding Windows 11 and its requirement for a Trusted Platform Module (TPM) chip, which is not standard on the majority of PCs and threatens to leave many newer Windows 10 PCs blocked from being upgraded.\nNormally the issues around a new version of Windows are system requirements, but here, the issue is the TPM chip. TPM is a specially designed chip that assists with security surrounding credentials. It ensures that boot code that\u2019s loaded, such as firmware and OS components, haven\u2019t been tampered with. It can also encrypt the drive contents to protect against theft. Microsoft is mandating that systems have TPM based on 2.0 specifications but few PCs do. Those that do ship with it have it turned off by default but it is easily activated.\nIt\u2019s an issue because Windows client and Windows Server share a whole lot of code. That\u2019s why Patch Tuesday fixes almost always apply to the Windows 10 client (Windows 7 is no longer supported) along with Server 2019 and 2016. The main difference between client and server is the services wrapped around the core operating system. So what happens to one usually happens to the other. But not in this case.\nMicrosoft server details\nComputerworld has been covering this story from the client side, so we will focus on the server side. And as it turns out, Microsoft handled the server software a lot better than it did the client.\nJim Gaynor, lead analyst with Directions on Microsoft, says the TPM module is a \u201cnon-issue\u201d because on June 11, 2020, Microsoft announced that Windows Server hardware certification would require UEFI and TPM 2.0 hardware for new server platforms introduced to market after January 1, 2021. If you missed that news, join the club. I think we were all a little distracted back then.\nServers that shipped with what was then being called \u201cthe next major Windows Server release\u201d (which is now knows as Windows Server 2022) preinstalled would have to have Secure Boot enabled by default.\n\u201cAs a result, the portion of the industry focused on Windows Server host hardware has fully expected Windows Server 2022 to require those capabilities, since Microsoft requires them for hardware certification,\u201d he told me via email.\nHe hypothesizes that for customers who are still on-premises and keeping up with the latest Server OS versions, they likely already have server hardware with UEFI and TPM support. For other customers, if they\u2019re not keeping up with the latest, then it\u2019s likely a non-issue. \u201cThey won\u2019t be adopting 2022 anytime soon. They\u2019ll adopt 2022 (if they aren\u2019t still considering 2019) with a hardware refresh,\u201d he said.\nMicrosoft made a lengthy blog announcement detailing its plans and intentions last June, and the OS isn\u2019t due until next year. So the Server team gave customers a lot more running room and just handled the whole thing much better than the client team.\nCompeting With Apple\nSo why did Microsoft drop this bombshell on its Windows user base? Ashish Nadkarni, group vice president in IDC's Worldwide Infrastructure Practice believes it\u2019s because Apple had a similar security chip, the T2, in its Macs.\n\u201cThey are being beat up by Apple [over the T2] making it a hardware conversation. By forcing people to use TPM they can say they have a similar feature,\u201d Nadkarni said.\nIDC did a study for Dell of what features customers wanted in a server, and TPM was at the bottom of the list. The reason he says is that TPM has not found much favor in servers because the server side had better drive security features like Dell\u2019s iDRAC and self-encrypting hardware in general.\nNadkarni notes that TPM only works if drive is physically compromised. For a stolen laptop, that\u2019s an issue. An unencrypted drive could be removed from the laptop and its contents compromised. So that\u2019s valuable to a Windows client.\nBut how many hard drives get stolen from a data center? Some, I\u2019m sure, but it\u2019s nothing compared to laptop theft. So for servers, TPM is low on the list of priorities.
