Microsoft introduced yesterday that Home windows 11 would require TPM (Trusted Platform Module) chips on present and new units. It’s a big {hardware} change that has been years within the making, however Microsoft’s messy method of speaking this has left many confused about whether or not their {hardware} is suitable. What’s a TPM, and why do you want one for Home windows 11 anyway?
“The Trusted Platform Modules (TPM) is a chip that’s both built-in into your PC’s motherboard or added individually into the CPU,” explains David Weston, director of enterprise and OS safety at Microsoft. “Its objective is to guard encryption keys, person credentials, and different delicate information behind a {hardware} barrier in order that malware and attackers can’t entry or tamper with that information.”

So it’s all about safety. TPMs work by providing hardware-level safety as an alternative of software program solely. It may be used to encrypt disks utilizing Home windows options like BitLocker, or to forestall dictionary assaults towards passwords. TPM 1.2 chips have existed since 2011, however they’ve sometimes solely been used broadly in IT-managed enterprise laptops and desktops. Microsoft needs to carry that very same stage of safety to everybody utilizing Home windows, even when it’s not at all times good.
Microsoft has been warning for months that firmware assaults are on the rise. “Our personal Safety Alerts report discovered that 83 % of companies skilled a firmware assault, and solely 29 % are allocating sources to guard this important layer,” says Weston.
That 83 % determine appears enormous, however when you think about the varied phishing, ransomware, provide chain, and IoT vulnerabilities that exist, the broad vary of assaults turns into so much clearer. Ransomware assaults hit the headlines weekly, and ransomware funds extra ransomware so it’s a tough drawback to resolve. TPMs will definitely assist with sure assaults, however Microsoft is banking on a mixture of contemporary CPUs, Safe Boot, and its set of virtualization protections to essentially make a dent in ransomware.
Microsoft is attempting to play its half, notably as Home windows is the platform that’s usually most affected by these assaults. It’s broadly utilized by companies worldwide, and there are greater than 1.3 billion Home windows 10 machines in use right this moment. Microsoft software program has been on the core of devastating assaults that made international headlines, just like the Russia-linked SolarWinds hack and the Hafnium hacks on Microsoft Trade Server. And whereas the corporate isn’t liable for forcing its shoppers to maintain its software program patched, it’s attempting to be extra proactive about safety.
Microsoft has a behavior of struggling to maneuver Home windows into the longer term in each {hardware} and software program, and this specific change hasn’t been defined nicely. Whereas Microsoft has required OEMs to ship units with help for TPM chips since Home windows 10, the corporate hasn’t pressured customers or its many system companions to show these on for Home windows to work. That’s what’s actually altering with Home windows 11, and mixed with Microsoft’s Home windows 11 improve checker, it has resulted in a variety of comprehensible confusion.
Microsoft’s Home windows 11 web site lists the minimal system necessities, with a hyperlink to suitable CPUs and a transparent point out {that a} TPM 2.0 is required at a minimal. The PC Well being Examine app that Microsoft asks individuals to obtain and test to see if Home windows 11 runs will flag techniques that shouldn’t have Safe Boot or TPM help enabled or units which have CPUs that aren’t formally supported (something older than eighth Gen Intel chips).
That’s left many attempting to determine if their system helps TPM or not, confusion with BIOS settings, and even individuals dashing to purchase separate TPM modules they don’t want. Some are even scalping TPM 2.0 modules on eBay!
Because of Home windows 11, individuals are scalping TPM2.0 modules as nicely now.

It additionally didn’t assist that Microsoft initially had a second webpage with contradictory info, one which it modified a pair hours after we revealed this story. In keeping with the unique model of the web page, the true minimal necessities had been TPM 1.2 and a 64-bit dual-core CPU that’s 1GHz or better, however the brand new web page now clarifies it requires TPM 2.0 and a processor that Microsoft has explicitly licensed as suitable — which could imply the whole lot earlier than an eighth Gen Intel Core and AMD Ryzen 2000 gained’t work.
We’re nonetheless ready for specific affirmation from Microsoft on the CPU requirement, however a rep confirms that TPM 2.0 shall be obligatory, and that the unique info on that web page was unsuitable. “The referenced docs web page was a mistake that has since been corrected,” an MS rep tells The Verge.
Microsoft is selling TPM 2.0 and performing checks for eighth Gen or newer Intel chips as a result of these are the necessities for licensed OEM {hardware} — the machines you’ll discover in shops with an inevitable Home windows 11 sticker. But it surely’s not clear whether or not the Home windows 11 replace will work on older machines both, and Microsoft is suggesting to us that it gained’t. We perceive Microsoft is presently placing collectively a weblog submit that can clarify the minimal necessities in additional element.
However that doesn’t imply your present PC is out of luck simply since you’re having points with Microsoft’s compatibility device. Until your CPU is very outdated, it most likely already has baked-in TPM 2.0 help.

Should you’re having points with the PC Well being App checker for Home windows 11, be sure to have “PTT” on Intel techniques enabled within the BIOS, or “PSP fTPM” on AMD units. The corporate’s system checker must also be much less complicated now: shortly after we revealed this story, Weston tweeted that the device will now be extra particular about why your PC isn’t passing muster.
We simply made updates to the Home windows 11 PC Well being Examine App. It now supplies extra detailed data on necessities not met. This could assist in instances the place people assumed CPU compat points had been TPM associated https://t.co/hTWMe16DWO pic.twitter.com/eZLTZMOdjT

What Microsoft is attempting to realize right here will profit the Home windows ecosystem in years to come back, alongside its new efforts for Xbox-like safety on Home windows. Microsoft simply completely dropped the ball on explaining that to everybody on day one.
Replace, 2:26PM ET: Added that Microsoft up to date its PC Well being Examine app, shortly after we revealed this story, to be extra particular about why your laptop isn’t assembly Home windows 11 system necessities.
Replace, 3:53PM ET: Added that Microsoft has modified its compatibility web page to say TPM 2.0 as a requirement as an alternative of TPM 1.2, and that particular CPUs could also be a requirement. We’re attending to the underside of this now.
Correction, 8:06PM ET: This story initially said Home windows 11 would possible nonetheless set up on PCs with entry to TPM 1.2 and older CPUs, as a result of that’s what we learn in Microsoft’s documentation. Microsoft has now corrected these paperwork to specify TPM 2.0 is a minimal requirement for Home windows 11.
