Windows 11 Megathread #2 – Build 22000.51 is live — Is my system compatible, TPM 2.0, Secure Boot and more

1 : Anonymous2021/06/28 18:48 ID: o9qooi

The first Insider Preview build of Windows 11, build 22000.51 is now live for Windows Insiders on the Dev channel. For this specific build, no standalone ISO will be made available.

If you wish to learn more about the Windows Insider program and join, you can do so here

Please remember, Windows 11 minimum requirements are subject to change and please do not install Windows Insider builds on a system where stability is crucial, only install on a system you are happy to wipe and reinstall at any moment.

The Windows 11 build 22000.51 via the Dev channel will only install if you are running an AMD Ryzen 2nd Gen, or Intel 8th Gen or newer CPU.

There is a workaround to this limitation, but please note, it is not known what, if any side effects may occur from doing this

Please use this thread to ask whether your system is compatible, for dedicated Windows 11 discussion, please use /

or /

Here are the system requirements for Windows 11

Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)

RAM: 4 gigabyte (GB)

Storage: 64 GB or larger storage device

System firmware: UEFI, Secure Boot capable (for both GPU and Motherboard)

TPM: Trusted Platform Module (TPM) version 2.0

Graphics card: Compatible with DirectX 12 or later with WDDM 2.0 driver

Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per color channel

Internet connection and Microsoft accounts: Windows 11 Home and Windows 11 in S mode now require an internet connection during setup and require the use of a Microsoft Account, no more local (offline) accounts

For a list of other requirements, such as Auto HDR and DirectStorage, please see here

The most important thing here, is the release build of Windows 11 will require a UEFI system, with CSM disabled and they will require TPM and Secure Boot to be enabled, in order to receive the Windows 11 upgrade, you will need an AMD 2nd Gen Ryzen / Intel 8th Gen or newer CPU. Windows 10 and previous Windows Operating Systems have not had such stringent requirements.

It's worth noting, the current Windows 11 Insider builds do not enforce the TPM or CPU generation limits, so this decision by Microsoft seems to be completely arbitrary.

Most modern AMD and Intel motherboards have some form of Firmware based TPM, which is different to Hardware based TPM solutions.

The first step you will want to do is make sure you are running the latest BIOS for your system.

If you are using an AMD platform, look for something called AMD fTPM or something similar, this can generally be found under the 'Security', 'Trusted Computing' or 'Advanced CPU settings' in most BIOSes.

If you are using an Intel platform, look for something called Intel IPT/PPT (Platform Trust Technology) or something similar, this can generally be found under the 'Security', 'Trusted Computing' or 'Advanced CPU settings' in most BIOSes.

TPM options are generally found in the same location as Secure Boot.

When enabling Secure Boot, you may have to set the key mode to Standard instead of Custom, before you can enable Secure Boot

When back in Windows, you can use Windows Key + R and type "tpm.msc", if it looks something like this, you are in business.

To check whether Secure Boot is enabled, you can open Windows Defender and go to Device Security, if you see this at the bottom, it means you Secure Boot is enabled.

I will update this thread if more information becomes available.

If you would like Microsoft to remove the TPM, Secure Boot, UEFI and CPU hard floor requirements for installing Windows 11, do make sure you submit feedback via the feedback hub.

3 : Anonymous2021/06/28 21:31 ID: h3d9w2z

Made a clean install.

Ryzen 7 1700

RX 580 (Windows Update Driver

Secure boot on

TPM 2.0

Edit: missing chipset driver from, WU doesn't have them either.

so i uave a question for all the tpm defenders... if microsoft is so concerned about hardware security that they want to lock you into using tpm secure boot and lock you into whql drivers... then why arent they pushing for the removal of known backdoors like the intel management engine or psp? what good is an encrypted boot loader if theres something running even below that that is potentially an open backdoor?

5 : Anonymous2021/06/28 19:03 ID: h3cp85k

I want to understand, what if I am running dual boot with windows and multiple linux OS's? How much fiddling would it require now with secure boot? I've always disabled secure boot as soon as I get a machine, never plays good with dual booting. And I always prefer my bootloader to be grub rather than window default.

6 : Anonymous2021/07/05 06:41 ID: h43rz5y

What happens when I disable tpm and secure boot after already having installed windows 11 with both enabled just for installation. Let's just say you might need to disable those. I don't need to btw, can't think of any reason why I might need to but just for the sake of knowledge. Would the OS crash? Or do you continue with windows 11 and it was just an installation requirement?

ID: h46apon

I'd like to know this too!!

ID: h46z7ed

The current Windows Insider builds don't impose the TPM or Secure Boot requirement, so this can't be tested, but unless you are using Bitlocker Drive Encryption, I'd guess nothing.

I've been in the Insider's beta program since Oct 1, 2014...;) I've seen a lot of new builds. The thing I would caution people about is only that these are all beta builds--99% of the time. Beta builds have bugs--sometimes they won't even install--though that is much less frequent today. The biggest mistake people make about the Insider's is in thinking this is Microsoft's "official" Windows release program--and it is nothing of the sort...;) If you don't like beta testing and bugs here and there, and you don't think you would enjoy installing up to 2-3 builds a month, then I think you would be better off sticking with the two official builds of Win10 per year, and the single official build of Win11 per year, that Microsoft will be releasing over the next few years. And yes, this first build of Win11 is very much a beta build...;)

ID: h3j81nt

If you don't like beta testing and bugs here and there,

So how is it different than a normal build:)

I can confirm that currently TPM can NOT be enabled in the BIOS of MSI gaming top end laptops despite running modern AMD processors

The models I have checked are the Alpha line (Alpha 15 A3DDK with AMD Ryzen 5 3750H and Alpha 17 (Alpha 17 A4DEK with AMD Ryzen 7 4800H) Both with non-declared models of their respective motherboards

So bear in mind that TPM and fTPM are not just a CPU-thing and will depend on motherboard capabilities and its BIOS

Has anyone been running benchmarks on Win11 builds with the new AMD CPUs?

There is a pretty widely reported issue with L3 cache performance (at least affecting the AIDA memory/cache benchmark).

However, it's not clear if it is actually affecting game/other benchmarks. Is anyone seeing degraded performance with the dev builds?

10 : Anonymous2021/06/29 13:24 ID: h3fqd0n

It's a mess. All kind of silly things are broken that weren't broken. Like copying files to windows on the taskbar, the back to desktop hitbox in the bottom right corner doesn't extend into the corner, can't log in with fingerprint anymore and so on.

But what's most and why I'm posting here. It broke Zen 3 performance.

Random memory latency and L3 cache bandwidth and latency took a huge hit. L3 Cache latency trippled from 10ns to 30ns and bandwidth went from 800-1000GB/s to 50-80GB/s. Verified with both Aida and Sisoft Sandra. Also 3D Mark is unstable. and so on.

Rolling back to Windows 10 (without insider preview pack) solves the problems instantly.

It broke ryzen multicore performance. Intel performance seems to be fine for the most part. I'm actually getting better overall speeds for multicore on my 8600k, but all my friends on Ryzen are seeing 15-35% decreases. I wonder if it's a microcode issue for windows 11.

ID: h3g0vn5

Spoke to some people that actually have a bit of insight and they told me that somehow Microsoft indeed chose to use an old microcode from April while Windows 10 is already newer..

Sounds either VERY sloppy to me or dirty.

ID: h3hdc96

It's a dev build, not sure what miracle you were expecting. But for the most part, considering it's a dev build. It's a lot stable!!

ID: h3y8l0r

Idk, people seem to be acting like it's the full build. Just look at the people bragging about using it on original zen cpu. They'll be in for a rude awakening on the official release.

ID: h3j5cpg

Expecting equal care for Intel and AMD parts.

And not to break things that have been changed that weren't broken. Changing for the sake of changing is not improvement. But don't worry I did use the feedback app and shared the things that I like and I don't. If everyone could do this then they have something to work with and hopefully we get a decent endresult.

I have fTPM enabled but not Secure Boot. But PC Health Check says my PC "meets all the system requirements for Windows 11."

12 : Anonymous2021/07/04 10:45 ID: h40f42u

This is going to be interesting if you swap your motherboard does that mean your not going to be able to boot into your OS anymore?

Anyway for those use windows in a VM (like me) you just need to do the following:

Add a TPM device to your vm config through virtmanager

<tpm model="tpm-crb"> <backend type="emulator" version="2.0"/> </tpm>

Now add support for secure boot

<os> <type arch="x86_64" machine="pc-q35-3.1">hvm</type> <loader readonly="yes" secure="no" type="pflash">/us/edk2/ovmf/OVMF_CODE.secboot.fd</loader> <!-- The irrelevant stuff is removed --> </os>

Notice the load element if you've got windows running with uefi already you need to change the OVMF_CODE.fd to OVMF_CODE.secboot.fd. With this done the microsoft pc healthcheck works and says your machine is compatible.

Once I get a second M.2 SSD i'll be able to see if DirectStorage works which it should do once passed through (question is do I have enough PCI-E lanes left over)

13 : Anonymous2021/07/12 20:51 ID: h4yod2s

Do you guys think Microsoft will add support for Ryzen 3 1200AF and Ryzen 5 1600AF, as they are Zen+ chips despite having CPUID of 1st gen Ryzen? Though it seems they don't give a f... and want Windows 11 adoption to be as little as that of Vista.

If Microsoft does not, it will leave a really bad taste in the owners of both chips like me, because not being able to upgrade through official means just because these CPUs processors report themselves as an unsupported ones will suck hard.

fTPM turned on Asus B450! Seems like a good time to start using BitLocker while I'm at it.

Was happy to see in BIOS: "AMD fTPM is a hardware TPM 2.0 implementation integrated in AMD AGESA code"

ID: h3e38wn

Make sure to save your bitlocker key somewhere for if your install breaks. You'll need it to not lose everything

15 : Anonymous2021/06/29 00:29 ID: h3dvkt9

Does the 11 preview support nested VM / Hyper-V?

Edit: It was supported for a while on Intel with windows 10 but not on AMD. 🙁

16 : Anonymous2021/06/29 03:24 ID: h3efiwz

There's something weird with the insider build aida64 reports very low L3 bandwidth, and other benchmarks like sisandra measure somewhat worse, new microcode for ryzen in windows 11 is bad even if game performance for some reason is not affected.

17 : Anonymous2021/07/03 23:13 ID: h3yvryi

I freaking facepalmed when I saw that I set my SSD as an MBR.

ID: h435ns3

There is a tool that Microsoft created called mbr2gpt I used it to convert my knew ssd to gpt

ID: h43xqqz

Yup I saw that the other day, pretty cool to see you don't even lose your data. I'll probably try it tho not gonna lie I'm sweating a bit, I hope it won't screw anything up lol

ID: h4wr492

has done this for years 🙂

18 : Anonymous2021/07/07 19:37 ID: h4e15to

I have a 1700x on an x370 and this build was delivered to my PC as a standard update as part of the dev channel.
The Asus Crosshair VI Hero BIOS doesn't indicate secure boot isn't actually running until you're on UFEI. I had to convert my MBR from UFEI to GPT using mbr2gpt in order to have secure boot enabled properly.

19 : Anonymous2021/07/23 22:44 ID: h6axzi8

The TPM manufacturers holds the Master Keys embedded into the chips at production time that are used to encrypt "securely" all your keys.

I'm sure they are randomly generated for every chip and discarded immediately once embedded ;>

20 : Anonymous2021/06/28 19:23 ID: h3cs3yt

Is there any benefit to using TPM over fTPM? I know my system should be in the clear (haven't run the test yet) but if there's any real benefit of the hardware component I don't mind installing it either.

21 : Anonymous2021/06/28 21:20 ID: h3d8e8k

Updated to win11 dev build. Ran cinebench 23 with my 3700x and got only like 10k points at multicore test (should be around 12k points)

ID: h3eoz7k

use the feedback hub, the amd reddit won't get your feedback to microsoft.

22 : Anonymous2021/06/29 02:58 ID: h3ecn79

"DirectStorage requires an NVMe SSD to store and run games that use the "Standard NVM Express Controller driver and a DirectX12 GPU with Shader Model 6.0 support." Does that mean a 5700 XT would support direct storage?

23 : Anonymous2021/06/29 04:26 ID: h3elrhm

Anyone else unable to enable core isolation or memory integrity despite meeting all requirements? Might just be a bug in this build, but not sure.

24 : Anonymous2021/06/29 13:55 ID: h3ftybr

I was able to install and am currently running Win 11 on 1st generation Thread Ripper 1950x.

ID: h3pxc5d

Yes, I'm running a first generation Ryzen - 1800x and just upgraded to Windows 11.

25 : Anonymous2021/06/29 14:53 ID: h3g18bs

How difficult is just upload the iso?

26 : Anonymous2021/07/05 06:30 ID: h43r6hy

Can I go back to windows 10 using system restore point????

ID: h458y5t

I just did this last night. It works just maybe make a backup of your users folder as I lost some save games that weren't in the cloud. Not sure why as most of my user folder stayed how it was just some parts got deleted.

I didn't use system restore point I went to the windows insiders page and chose the option to revert to older version of windows.

27 : Anonymous2021/07/07 16:44 ID: h4ddjap

All I want to know about Windows 11. Has the ever growing size of the Winsxs folder been addressed/fixed?

28 : Anonymous2021/07/07 20:02 ID: h4e4owo

I have a AMD Ryzen 1700 installed on a prime x370-pro motherboard.

I just enabled the TPM thing but the secure boot on Win Defender is not visible (I guess I also need to find and enable that too)

I have seen that a 1700 is not compatible so what is my recommended upgrade options? I'd like some suggestions for future proofing my PC for Win 11.

ID: h4eaii5

It's too early to start preparing. Wait and see, Microsoft may change their minds and/or more requirements to come. Windows 10 will be supported until at least 2025 and then they usually extend out the support windows on top of that.

29 : Anonymous2021/07/14 22:20 ID: h57g6k7

Gotta say, with my 5950X, Win11 is running very snappy. Only issue I had was the realtek 2.5gb network driver crashing the system, had to disable the driver in the device manager and only use the 1gb intel nic.

30 : Anonymous2021/06/29 01:45 ID: h3e48v0

still can't stand why they're dropping support for even beast i7-7700k and welcome newer Atom chicks :))))

ID: h3e4hoq

I'm running my 7700k until I can get a 6900x or 7900x, whichever provides a massive boost to IPC over current Zen3 chips. If that means no Windows 11 for the foreseeable future then yay me I don't care, just means I won't be a guinea pig for a buggy new OS.

ID: h3e5hg1

Will probably eventually work fine. These newer CPU architecture are better, and 8th gen was when Intel fixed a bunch of security flaws... so...

ID: h3egg4z

7700k? More like i3 10105f level performance deep dab. Such an epic loss
