Re: TPM
When I use the word "requirement", enforcement is implicit. It isn't a requirement if it isn't required.
Looking at the Win10 "requirements", it says that TPMv2 must be implemented and enabled by default in PCs made after a certain date (how does it know the mfr date? Implied by CPU choice?). "By default" implies that it can be disabled by user choice, which then raises the obvious question - if Win10 can start without it then it isn't a requirement.
I didn't look at Win11 requirements since I don't plan to use Win11 until others have worked the kinks out. Unless MS wants to pay for my time of course.

Re: TPM
Even "enforcement" can take different forms: Consider the PC manufacturers that wanted to sell PCs with a Windows sticker and Windows 10 pre-installed after 2016. In consequence, the majority of PCs sold in the last 4 years will probably have a TPM 2.0 (either as a chip or as a UEFI firmware TPM, both fulfills Microsoft's "requirements" AFAIU). But let's not focus on Windows 10 too much.mpack wrote:When I use the word "requirement", enforcement is implicit.

Re: TPM
I agree. Since that document states that the minimum hardware requirements are not enforced during an install or upgrade of Windows 11 on a virtual device, we should be able to move a vm to Windows 11 and decide if the performance suits our needs. I will certainly give that a try when Windows 11 is released.fth0 wrote:Well, yes and no. IMHO, a TPM 2.0 is a requirement for physical hardware, but not for virtual machines. Download the Windows 11 minimum hardware requirements document linked within Windows minimum hardware requirements, and especially read chapter 5, which is about virtual machines.

Re: TPM
Let's not lose sight that the OP mentioned TPM and Win10, so both are on topic, more so than Win11 in fact. I'm allowing the discussion to include Win11 since I suspect it's just a marketing term for the next Win10 feature update.fth0 wrote:But let's not focus on Windows 10 too much.

Re: TPM
That again is a yes and no thing. Under the hood, I suspect Windows 11 will be almost exactly the same as Windows 10 21H2, which is also due any day (and will not be much different to the latest Insider build). That does not mean Windows 11 will have the same look and feel or the same hardware restrictions. If Microsoft keep to their current timetable for Insiders, we will know later this week.

Good catch, thanks for pointing that out, I have an upgrade install going now on a Windows 10 guest with EFI enabled (I'm not sure even that is needed though)BillG wrote:I agree.

Re: TPM
Unlikely. The same link says that Windows 10 20H2 requires a 5th gen Intel CPU, which I currently run on an i7-2600. Heck, I previously upgraded to Windows 10 1909 on a Core2Duo.fth0 wrote:mpack wrote:Is it definitely going to be needed for Win11?That will already be enforced by the CPU requirement (e.g. Intel 8th gen. CPUs). See Windows Processor Requirements for the details.mpack wrote:Because that would exclude Win11 from running on a bunch of older PCs.
The requirements that Microsoft has stated publicly is a 1.0Ghz 2-core CPU. I'm honestly not sure what those links mean, given that they are inaccurate for Windows 10.

Re: TPM
Agreed. Ultimately, that means Windows 11 will run on the (physical or virtual) hardware that it will run on, no more, no less. Anything else is speculation, based on whatever Microsoft documentation is there available. And even the released Windows 11 itself will be updated continuously, so there is no guarantee for anything.

Re: TPM
Yep. The Windows 11 specs state that only 8th generation Intel Core processors and higher are acceptable, but my Insider i-7 7700 was offered the preview version so that Insiders can assess how Windows 11 runs on hardware not on the list. I wonder what other restrictions have been waived for Insider previews.
I suspect that initially they are only allowing hardware they have actually used in their testing. Things may change later.

Re: TPM
VirtualBox's lack of TPM support prevents you from installing the W11 dev build via Windows Update in a VM running W10.
I also can't find W11 builds on Microsoft's Insider ISO page (only up to W10 Redstone 1 are available in my case), so I'm doomed to either use Hyper-V (painfully slow, but the dev build does show up), VMware Workstation Pro (which costs money) or use some random ISO from the Internet.

Sez who? Reference please. Your statement seems to directly contradict Microsoft's official "in a VM" requirements already quoted above.andreyyshore wrote:VirtualBox's lack of TPM support prevents you from installing the W11 dev build via Windows Update in a VM running W10.

Re: TPM
That does not surprise me. Most beta builds are only available as updates to Insiders. ISO releases are rare.andreyyshore wrote:
