Win11SysCheck and WhyNotWin11 tell you why your PC is incompatible with Windows 11

Microsoft released a tool this week, called PC Health Check, that may be run on Windows devices to determine if these are compatible with Microsoft's upcoming Windows 11 operating system.

The first iteration of the tool returned Yes or No, basically. While that is okay if a device is compatible, not revealing why the device is not compatible is a problem. Even recent computer systems may not be compatible with Windows 11; most of the laptops and PCs that Microsoft sells under its Surface line are not compatible. You had to check each component that is tested manually.

For the CPU, you had to find out the make and model on the device, and then search for it on Microsoft's listing of compatible processors by AMD, Intel and ARM. Microsoft has updated the tool in the meantime to highlight why a device is not compatible.

Update: You can no longer Download the PC Health Check app, since Microsoft has pulled it from their servers to avoid flak from users while the company tests Windows 11's compatibility on older systems such as the 7th-gen Intel chipsets. But you can use third-party tools like Win11SysCheck and WhyNotWin11 to determine if your computer will run Windows 11, and why it may not. End

Win11SysCheck

Win11SysCheck is an open source tool that tells you if a PC is compatible with Windows 11, and gives you the reason if it is not. It is more detailed than Microsoft's own tool, as it lists checks and the outcomes in the interface.

windows 11 syscheck

You can download a precompiled copy of Win11SysCheck form the project site. Note that you may get a SmartScreen error when you run the tool on Windows -- an installation is not required. The tool is new, and that is the reason for the error. Just ignore the error and continue with the execution.

You get a DOS window in which all checks and the returned values of them are listed. In the case of my Surface Go device, Win11SysCheck confirmed that the processor is the culprit by stating (Unsupported Intel CPU detected); this gives you a clear message.

WhyNotWin11

whynotwin11

WhyNotWin11 is the second open source tool that you may run. Unlike the former, it comes with a graphical user interface and provides more details on the compatibility status.

Note that you may get a SmartScreen error as well, for the very same reason than before.

The program checks all known compatibility requirements and displays whether the machine it is run on passes the requirement. It visualizes the result of the scan using colors.

Closing Words

There may not be much that you can do about it though, depending on a number of factors. Laptops, for instance, have fixed processors, which cannot be replaced.

It is still unclear if Microsoft will use the compatible hardware when administrators initiate upgrades from Windows 10 devices, or if the list of supported CPU is designed for PC manufacturers who plan to create new PCs with Windows 11.

Windows 10 is supported until 2025. Microsoft has not said much about that, but it is likely that this entails security updates for the most part.

Now You: should all Windows 10 devices be allowed to upgrade to Windows 11?

    I believe that a ham sandwich is better at telling you if your system is compatible than the official PC Health Check “app” by Microsoft. First all it could do was say NO. NOW if you install it, it wants to install an update for itself, and fails. And trying to run it again, fails and fails and fails and fails again TRYING to update something. Microsoft have hired drunks and potheads to do their development. Real VISIONAIRES I must say.. Miserable fail after miserable fail, year after year..decade after decade.. Why do we put up with this? Why do governments USE this GARBAGE?????

        There’s no technical reason not to support older Intel CPUs, and it has been proven because Win 11 can be hacked to install on them. I’d call them a lot worse than M$.

    As someone said elsewhere, the free upgrade path to Windows 10 was a huge blunder by Microsoft because a lot of people didn’t bother buying new PCs so they and the hardware makers lost a lot of money. That’s why you still see a lot of PCs from the early 2010s still in use today, and they really don’t like that. Now they’re making it as annoying as possible to upgrade to Windows 11 to push new PC sales, via artificial limitations, knowing that the average consumer will go “to hell with it” and buy a “Windows 11 Ready PC” this fall.

    They likely just renamed what was supposed to be Windows 10 21H2, added higher requirements and called it a day to push new PC sales.

    The change in system requirements is the real reason why
    there is Windows 11 rather than a Windows 10 feature update.
    A Windows 10 feature update could not demand different hardware.

    Just looking at the Windows 11 system requirements I can see that the
    TPM version is the only requirement my 7 year old desktop does not meet.
    I am quite content to run this system on Windows 10 for the next three years.

    Clearly NOT!

    Many so-called Windows 10 devices were made for Windows 7, that have old hardware that isn’t even supported by the vendors anymore, be it with Dell, Nvidia, Intel, and more.

    The last thing MS wants with 11 is having poor/daft users complaining to them about old hardware issues, that also involve security risks.

    Also, those poor user can always move to Linux, so all is not lost for them.

    More proof that Microsoft developers are completely unskilled and useless. They can’t even get a simple check tool right. The thing also uses over 100MB of RAM. We have to turn to third party programs like Win11SysCheck that do it better and more efficiently than Microsoft’s own tool. Sad when one person at home could make a better program than a trillion dollar company.

    WhyNotWin11 is portable, not installed, and Windows Defender gave it a pass. I didn’t give Win11SysCheck a try. (I’m in no hurry to move to Windows 11, but I checked out my 2020 LG Gram 17 laptop out of curiosity and, unsurprisingly, WhyNotWin11 says it’s compatible.)

    I got to thinking that a tool like this would be really useful for estimating the compatibility of various Linux distros with a given device. Sure, you can always run a live instance (for a lot of distros, at least) and systematically try to find out what does and doesn’t work, but it would be nice to be able to get a quick heads-up on which distros, if any, support your fingerprint reader, webcam, switchable graphics, and stuff like that out of the box. If such a utility exists, I’ve never heard of it, and if it doesn’t, it sounds like a good open-source project for DistroWatch to shepherd. I’m guessing that the results matrix for a Linux-compatibility utility would not be a simple “Yes/No” but rather “Probably/Maybe with Hacks or Tweaks/No.”

    Windows 10 has been quite usable, by and large, but I’m unhappy with the measures I’ve had to take to preserve some small degree of privacy and user control. Those drawbacks don’t look set to change for the better in Windows 11 and I still plan to migrate to Linux — maybe to Kubuntu or MX KDE or Fedora KDE, since KDE is my favorite desktop environment, and otherwise maybe to Linux Mint Cinnamon. What’s holding me back on my “new” laptop is battery-longevity-management concerns, thermal-management concerns, *terrible* Samba performance, and (to a significantly lesser degree), the fact that my fingerprint reader is completely unsupported (it’s nice but hardly essential). I guess if I were to dump Windows 100%, poor Samba performance would no longer be an issue.

    As for MacOS, it’s the preferred system for a number of people whose experience and opinion I respect, but the hardware price premium can be *eye-watering*, the walled-garden approach is off-putting, and for privacy we have only Apple’s promise — which isn’t good enough for me. (Remember when Google’s motto was “Don’t Be Evil”?) Linux being open-source, it’s a lot harder for covert privacy threats and violations to go undetected.

      Oops, misinterpreted that result. Disk is actually GPT and this is confirmed via Disk management properties (https://ibb.co/PZTPNB3). So, Moin has its problems too.
      Between all three, my laptop is AOK for Windows 11. Bear in mind, Microsoft checks at the time of installation have the final say.

      Moin also reports my CPU is OK but is ‘not listed’. In other words, what utility tools report probably depends how and where they chase their information.

      Summing up. If you are keen to install Windows 11, bide your time. The Microsoft test AT INSTALLATION TIME will be the ultimate arbiter.

    If Windows 10 is supported until 2025, then starting in 2025, you must use Windows 11 if you want a supported version of Windows.
    But Windows 11 will only work with recent CPU’s.
    So many people will be forced to spend their money on buying new hardware, while for many their current hardware is working fine and is fast enough.

    This is wasting natural resources and energy on building new hardware and wasting people’s money. For poor people, buying a new computer is a huge investment.
    And this in a time when we our mismanagement of the environment (climate warming) is causing us alot of economic damage and loss of life.

    Read this manual very good. For TPM to change, a few settings in the BIOS must be disabled (TXT and something of Intel security).
    I think this can not be performed by common PC-users.

    My TPM check now gives TPM2.0.

      VirusTotal does not set scan options for the AV vendors. They do it themselves. With heuristic checking set, AVs are inclined to over-report. I am only guessing but some of vendors may think they get a competitive advantage when their AV says malware is detected while other vendors report all is clear. VirusTotal results are not Gospel-truth. They are a guide. You need to apply judgement.

      My threshold is 3 positives before I do something about it (unless one is a top AV vendor, when I become more cautious). That ‘something’ may be abandonment of the software or deferral of installation to allow the software seller time to correct whatever it is that is causing the positive flag. I have been known to contact the software seller, advise the result and see how they respond. The response needs to be evaluated too. “Does not contain malware” as a statement never convinces me anything is clean.

      Just to make you feel even better, a totally clean VirusTotal result doesn’t necessarily mean software is free of malware. It only means malware has not been detected in the sample. There is always a chance you’ll be testing a something with previously undetected malware.

      What VirusTotal is very good at is detecting well-know malware. Lot’s of positive results from top AV vendors is very much a Danger Will Robinson warning.

    I have the Intel Core i5-4200M processor, not on the list in the article for Windows 10 20H2, but my system says I have Windows 10 Pro 20H2 and my computer works to write this.
