Attention Everyone: Under no circumstances download those ISO files, as sha256 hashes do not match those provided by official Microsoft sources. I have tried suggested file en-us_windows_10_iot_enterprise_ltsc_2021_x64_dvd_257ad90f.iso and it does not match any of these hashes. Nor there are references to vendor websites for vendor specific ISOs. This means probably there is a spyware inside or something else. But there is zero guarantee these files are free from spyware.

These are official hashes from Microsoft website:

    Well yes, but actually no. The evaluation iso is not the full version. You can use it for up to 360 days(90 days+3 reactivations). You can't activate it and continue using it forever. You also can't upgrade it to the full version, you need to reinstall windows.

    Microsoft provides full versions of Windows LTSC on MVS, M365 Admin Center and OEM Portal but for them, you need to pay a high subscription fee. There is no way Microsoft will give out hashes of the actual full versions of LTSC builds to the public unless you're a bussiness/enterprise entity and bought at least five copies of it.

    What this means is that you have to trust reputable forums like MyDigitalLife for hashes. The method is illustrated here.

        Staycalmsyndrome For me, I would need at least trusted source from one company which mentions hash that I have. For example Dell does it, but it does not match. Sadly, security comes first for me. You could literally plant there key logger and traffic logger, and then use generating AI to give you pretty much everything 🙂

          I have installed latest windows 10 and it feels much better than windows 11 on my machine. Windows 11 has a lot of visual crapware I suppose and maybe old hardware is not really optimized for it, even if drivers are released.

            There are no new drivers for my old hardware. The catalog when in Win 11 has the same old ones as with Win 10. I don't like the interface of 11, so it's fairly safe to say I won't be moving to it (on this hardware anyway).

            It's simply Windows 11 that is to blame. They changed the whole video system.

            For example, my video player that shows me video files completely smooth under Win 10, has problems with stuttering in Windows 11. They messed it all up.

                Reinhard62 have you ever tried disabling Hardware Accelerated GPU Scheduling in win11?

                  If anyone would need it, this is as close as possible to official checksums,
                  https://thewindowsupdate.com/2021/05/21/windows-10-21h1-may-2021-iso-file-checksums/

                  But be careful with those IoT versions. I see a lot of satelite websites referecing hash values, but many of them very questionable. Some claim to be american websites, but actually registred through Russian registers (no offence to any Russians on this forum, it just the way it is right now). Others throw reddit links to forums with presumable hash values on microsoft servers, and later have comments that it does not work, so they share in the comments hash values, luring people to belief that those are legit. If you do not take hash values directly from microsoft servers, you are risking. And there is a lot of potential social engineering going on. And having these enterprise copies installed within organisastions, with planted malware, is ideal later for various broad scale operations.

                  https://thewindowsupdate.com/2021/05/21/windows-10-21h1-may-2021-iso-file-checksums/ Is also big risk, as usually social engineering to build trust can take decades.

                  Personally I just finished my Windows safety-check and found these (with old monitors and nVidia driver 528.02):

                  Win10 21H2 is completely safe for me

                  Win10 22H2 makes some eyestrain already, which is bad after longer usage

                  Win10 22H2 KB5051974 from Feb.2025 makes even more eyestrain, i can see/feel the difference when toggling this KB

                  Win11 all versions are making the highest level of eyestrain, right from the first (21H2) version

                  Tell me this is not an experiment from M$… Well whatever, because they all can do whatever they want without control.

                  Other than that, monitors after somewhere like 2017 and newer nVidia drivers are making the high level eyestrain themselves already.

                    Could you list your equipment (cpu, mb, grapfic, monitor) and win10 21h2 build?

                    Currently I also testing win10 21h2 19044.1288

                        What does "toggle" the KB mean? Is there a quick way to test different ones and toggle back and forth?

                            Oshim Hey btw, what GPU/monitor/cables are you using with this? I've been trying tons of different combinations lately and the physical symptoms vary without any of them feeling 100% comfortable

                              simplex CPU is Ryzen 9 5950x, MB for it is Asus Crosshair VIII Hero Wifi, graphic is Asus RTX 3080 OC (very first gen.), monitor is an old Asus VG278HE

                              Group policy ist set to stay on 21H2 (via registry), so Windows Update goes no further than that.

                              I have now the same Win 10 21H2 installed on my small HP Elitebook 840G3 and all the drivers are up to date (in contrast to nvidia driver 528.02) and all still feels safe after a week of use.

                              Win is then this version:

                              Edit: second monitor is an old Samsung T220 and I run both monitors over Delock-61766 DP to VGA adapters.

                                That update did change DWM.

                                As for what exactly, that is a different question 🙂
