Home windows 11: Microsoft stands agency on {hardware} necessities

Weeks forward of the official launch of Home windows 11, Microsoft at present introduced minor adjustments to the minimal system necessities for its new working system. House owners of comparatively latest PCs working seventh Gen Intel Core CPUs or first-generation AMD Zen CPUs who have been hoping for a partial reprieve ought to put together to be upset. 

In an unsigned put up on the Home windows Insider weblog, the corporate introduced that it’ll make “a small variety of additions to the appropriate processor checklist … however in any other case will keep the minimal system necessities as initially set.” 

Additionally: Microsoft leaves a loophole for these eager to run Home windows 11 on ‘unsupported’ {hardware}

The corporate additionally mentioned it is releasing a brand new model of its compatibility checker for members of the Home windows Insider Program and can make that device typically obtainable “within the coming weeks”: 

As we speak, we’re releasing an up to date preview model of the PC Well being Examine app [download] to Home windows Insiders. This up to date model expands the eligibility verify performance with extra full and improved messaging on eligibility and hyperlinks to related assist articles that embrace potential remediation steps … As we speak, we’re additionally concurrently releasing variations that assist 64-bit Home windows, 32-bit Home windows, Home windows on Arm and Home windows 10 in S mode PCs to Home windows Insiders. Home windows Insiders can present suggestions on the PC Well being Examine app by going to Suggestions Hub > Apps > PC Well being Examine.   

Credit score: Microsoft

The core necessities to run Home windows 11 are unchanged from people who have been revealed as a part of the unique announcement: A PC will want a minimal of 4GB of reminiscence and 64GB of storage; UEFI safe boot have to be enabled; the graphics card have to be appropriate with DirectX 12 or later, with a WDDM driver; and a Trusted Platform Module (TPM) have to be included. 

As for these additions to the appropriate processor checklist, the checklist is certainly brief. Two households of server- and workstation-class Intel processors at the moment are on the checklist: the Core X-Collection and the Xeon W-series. The one mainstream Intel CPU added to the checklist is bound to lift eyebrows: Intel’s Core 7820HQ additionally occurs to be the CPU that ships with Microsoft’s expensive Floor Studio 2.

The checklist of supported AMD processors did not change. Microsoft mentioned it “fastidiously [analyzed] the primary technology of AMD Zen processors in partnership with AMD” and concluded that none of these CPUs deserved to be added to the supported CPU checklist. 

Within the the rest of the lengthy (almost 2000 phrases) weblog put up, the Home windows crew reiterated the rules it is counting on to justify the brand new system necessities. Imposing the stricter requirements, they argue, will make Home windows 11 PCs extra dependable and safer than their predecessors, along with being extra appropriate with trendy purposes. 

When it comes to reliability, Microsoft says its telemetry makes a robust case for the brand new requirements. “Units that don’t meet the minimal system necessities had 52% extra kernel mode crashes,” the corporate reported. “Whereas gadgets that do meet the minimal system necessities had a 99.8% crash free expertise.” 

That is a curious change in scales there. Changing these two statistics to a standard scale means that the older PC designs, absent different points, ought to nonetheless have a virtually 99.7% “crash free expertise.” 

Microsoft is on extra stable floor relating to the safety argument. The TPM requirement, for instance, helps hardware-based authentication and in addition allows safe storage of Bitlocker disk encryption keys. The UEFI Safe Boot requirement has already been a part of the Home windows PC necessities since 2013 and is efficient at blocking pre-boot ransomware assaults equivalent to NotPetya.  

Newer CPUs are designed to assist virtualization-based security measures that stop dynamic code injection into the Home windows kernel and in addition improve the safety of kernel-level drivers. “The USA Division of Protection (DoD) requires virtualization-based safety on Home windows 10 for his or her gadgets,” Microsoft argues. “Whereas we’re not requiring VBS when upgrading to Home windows 11, we imagine the safety advantages it gives are so necessary that we needed the minimal system necessities to make sure that each PC working Home windows 11 can meet the identical safety the DoD depends on.” 

The unstated piece of the CPU puzzle right here is the vulnerability of older CPUs to safety exploits collectively referred to as Spectre and Meltdown. Though Intel and Microsoft have collectively shipped microcode updates and Home windows system-level patches that mitigate the impression of these exploits, there is not any remedy, and the patches are recognized to have an effect on system efficiency. 

Microsoft says there is not any connection, nevertheless it’s a exceptional coincidence that the checklist of weak Intel CPUs contains just about all processors designed and offered in 2017 and early 2018 which might be unsupported on Home windows 11. As I famous on the time, “[W]hile software program patches can mitigate the consequences for now, the long-term answer entails elementary adjustments to CPU design that would take years to achieve the market.” 

A January 3, 2018 bulletin from the safety consultants at CERT (a associate of the U.S. Division of Homeland Safety) was much more blunt: The one answer for Spectre/Meltdown assaults? “Exchange CPU {hardware}. The underlying vulnerability is primarily attributable to CPU structure design selections. Totally eradicating the vulnerability requires changing weak CPU {hardware}.” 

Almost 4 years later, it appears to be like like Home windows 11 goes to play a significant function in that wholesale, wrenching substitute cycle. Anybody who intends to proceed utilizing older {hardware} will stay on Home windows 10, with that working system supported till October 2025.

What occurs after that’s anybody’s guess.
