Bottom line: Some PCs sold relatively recently, say in the last three years, may not run the new OS.
Microsoft couched the harsher requirements — relative to previous OS upticks, anyway — as necessary for security purposes. That’s the case, too, with the requirement of TPM, or “Trusted Platform Module,” version 2.0, for its ability to securely store encryption keys and the like.
Microsoft called TPM 2.0 “a critical building block” for security and contended that “PCs of the future need this modern hardware root-of-trust to help protect from both common and sophisticated attacks like ransomware and more sophisticated attacks from nation-states.”
All this led to confusion right from the start. Which PCs would run Windows 11? Which might? Microsoft botched the opening round so badly that it yanked a compatibility checker and rewrote (or clarified, your pick) pieces and posts about requirements multiple times, sometimes with acknowledgements that it was doing so, sometimes, well, without.
Free upgrade to Windows 11
Microsoft will not want to repeat the Vista Capable mistake with an official declaration on each PC. Instead, sellers will mark such systems with the “Free upgrade to Windows 11” phrase.
Microsoft may clarify this, but if that’s all the company will do for available PCs, it smacks of an obtuse and opaque manoeuvre meant to avoid responsibility. A label reading “Free upgrade to Windows 11” guarantees nothing about compatibility.
The simplest solution would be to mark devices “Will run Windows 11,” but something that straight forward would risk a repeat of Vista Capable. No surprise — that’s not the direction Microsoft went.
OEMs (original equipment manufacturers) don’t have the luxury of dodging the question. They’re using an if-we-have-it-then-it-will-run-11 tactic to inform potential customers that their wares are capable of running Windows 11. Some have already done so.
HP, for example, tells customers “Our current Windows-based PCs will be upgradeable to Windows 11 when it’s available later this year,” albeit with a caveat that some features require specific hardware. Likewise, Dell states, “All Dell PCs with Windows 10 currently being sold on dell.com will be able to upgrade to Windows 11” on its website.
Ironically, Microsoft hasn’t followed the lead of Dell and HP; pages touting its own Surface line do not make the same claim that all will run the new OS. There is some copy about the compatibility checker, however, the one Microsoft withdrew and is reworking.
Older devices can still ‘run’ Windows 11
It’s no coincidence that Microsoft announced Windows 11 and the “Cloud PC” concept dubbed “Windows 365” within three weeks of each other.
Unlike previous OS turnovers, Microsoft has an end-around it can offer customers — commercial customers initially, but you can expect it to filter down to very small businesses/consumers later — who find themselves with hardware that can’t meet the operating system’s system requirements.
According to Microsoft, the virtualised instances of Windows 11 that Windows 365 will create, store, and maintain on the firm’s Azure service will stream to any device equipped with a browser and connected to a sufficiently fat pipe to the Internet. The local PC, if that’s what it is, could be powered by a not-suitable-for-Windows-11 6th-generation Intel processor, and it wouldn’t matter.
Computerworld expects that Microsoft will use this to pitch Windows 365 to organisations that want to move to Windows 11 but that have a heterogeneous collection of desktops and laptops, some able to run the OS natively, some unable to as much as boot up 11. While Windows 11 could be deployed to the former, the latter would need to be physically replaced with newer devices or set up with Windows 365 licences.
Even if the organisation intended to replace the aged PCs with newer, physical devices, Windows 365 could be used until their replacement cycles come around.
