Note — I am personally not recommending upgrades to Windows 11 at this time. I have some issues with how Microsoft is handling things which I will discuss in a future post. However, if you would like to upgrade then I will still do my best to offer support. The purpose of this thread is to discuss what is needed to get Windows 11 running on Precision mobile workstations, with an emphasis on systems released before 2018, which Microsoft is not officially supporting. Windows 11 was released on October 5, 2021. The launch is starting with new PCs releasing late in the year. Existing PCs won't be offered the upgrade through Windows Update right away; they will start offering it to new PCs only and broaden eligibility gradually through mid-2022. "Go-getters" are able to go and download the install media and perform an upgrade on their own at any time after the official launch. Windows 11 is a free upgrade over Windows 10, it is accepting old Windows product keys for activation going all the way back to Windows 7. Microsoft has posted system requirements for Windows 11. Most systems will easily meet these requirements, but there are two big ones which will be trouble for many users: * A "compatible 64-bit processor" means anything older than Intel's 8th generation is not supported. (Microsoft is supporting select 7th-gen CPUs on systems with all-DCH drivers, but that is not the case on Precision systems of that era.) * Trusted Platform Module (TPM) version 2.0. (You can check your TPM version by looking in Device Manager under "Security devices".) Which Precision mobile workstations are supported? Dell Precision workstations released in 2018 or later have 8th generation CPUs. That is Precision 3530, 5530, 7530, and 7730. These systems also have TPM 2.0. These models and any successor models should meet the requirements for Windows 11 easily. Dell has posted their own supported model list which aligns with this. https://www.dell.com/support/kbdoc/...ed-for-upgrade-to-windows-11#Precision-DT-W11 What about systems that do not meet the requirements? Microsoft would recommend that you do not attempt to install Windows 11 and stick with Windows 10, which will still receive security updates until October 14, 2025. CPU requirement There is no option to upgrade a system from an unsupported CPU to a supported CPU. A motherboard swap would be required, and while some systems can be upgraded one generation if the chassis is compatible, the first 8th-generation system (Precision 7X30) came with a chassis refresh. TPM requirement Precision XX10 and XX20 systems (2015-2017 release years) qualify for the TPM 2.0 firmware update. Older systems have TPM 1.2, going all of the way back to the Precision M65 (released in 2005). Microsoft previously noted in the requirements that the TPM 2.0 requirement is a "soft floor" and TPM 1.2 is the "hard floor"; however, this note has been removed. Validity of the system requirements This is my personal opinion here... You can take these requirements and throw them in the trash. Nearly all systems that can run Windows 10 will be able to run Windows 11 without issue. Microsoft posted a clarification on the requirements and the reason for setting the bar high for CPU and TPM support is for security, not for performance. They are also preferring newer systems which have DCH drivers for "reliability" reasons. At present, the TPM requirement has a trivial workaround and the CPU requirement is not enforced at all. I've been reading reports on users who have upgraded old systems and I haven't seen any major issues popping up. Systems with older CPUs or without TPM support will miss out on some security features (...which is already the case with Windows 10) but should otherwise be fully functional. Of course, these systems will remain "unsupported" by Microsoft, so there could be issues yet to be discovered that will go unfixed, or new issues that pop up later. So it's basically a "try it at your own risk" situation, but I think that the risk is pretty low. How to install or upgrade to Windows 11 Systems that meet the system requirements The preferred approach according to Microsoft would be to wait until Windows 11 is offered to your system via Windows Update, and upgrade at that time. However, you can upgrade early by downloading the installation media (ISO) and using that. Installation media can be downloaded here: https://www.microsoft.com/en-us/software-download/windows11 Systems that do not meet the system requirements These systems will not see the Windows 11 upgrade offer through Windows Update, but upgrading using the installation media (ISO) is still possible. The installer will put up a warning about the system being unsupported that you must click through. https://www.microsoft.com/en-us/software-download/windows11 One thing mentioned in the warning is that unsupported systems may not be "entitled to updates". We'll find out on October 12 if the regular monthly cumulative patch is offered to systems with unsupported CPUs or not. I personally suspect that such unsupported systems will get monthly cumulative patches automatically, but not feature upgrades — those will have to be installed manually. Feature upgrades will be released yearly, in the fall. The installer will enforce TPM and Secure Boot requirements. TPM 1.2 seems to be accepted, so all Precision systems from the past 15+ years should be good there; just go enable it in the BIOS if necessary. Secure Boot is available on Precision systems released in 2012 and later (with Intel 3rd-gen CPU or better). You can bypass the compatibility checks if you need to. Microsoft has some documentation on it: https://support.microsoft.com/en-us...ndows-11-e0edbbfb-cfc5-4011-868b-2ce77ac7c70e [Edit] Update 2022-05-17 It looks like Microsoft is making the TPM requirement more strict with Windows 11 version 22H2 (launching fall 2022). The bypass that they have previously documented does not work. Users who have upgraded systems that "do not meet the system requirements" may have to jump through hoops to upgrade to Windows 11 version 22H2 beyond just sticking a registry setting in and running the upgrade off of the Windows 11 22H2 ISO.

I'm a believer in letting information flow to you, and not having to go and seek it out. In light of this... I'm scraping the Dell support/driver pages and using it to create an RSS feed. If you use a feed reader and one of these systems, you can use the feed to be informed of when new drivers drop. The feeds also include BIOS updates and some Dell software application updates. Right now I'm only grabbing drivers for Windows 10 and 11 (no Linux or older versions of Windows). If there are any other systems that you'd like to see a feed for, let me know and I will add it to the list.
