    Hey guys, im having trouble finding a guide to diffrent ltsc/ltsb builds.

    I know there is a:
    2015 release
    2016 release
    2019 release
    pherhaps theres other releases as well?


    If anybody can give a quick rundown of each release that would be great :)
    What im specifically interested in is whether the telemetry is harder to rip out in the newer ones. Are the updates still not forced, and operate just like before? Is there a build with hardware compatibility issues?

    To avoid hardware compatibility issues (better said performance issues) the release date of the OS should be after the release date of the particular CPU / chip set model / type.

    This means generally LTSC2019 (the latest 1809) and those 2 LTSB versions are not recommended for CPU releases after September 2018.
    LTSB2015 (1507) was released on July 2015 and LTSB2016 on August 2016 (although it's 1607)

    I personally prefer LTSC2019
    All points listed by Dude Guyman are valid.

    On LTSB I don't like OneDrive, the WU issue and the fact it has no dark theme for file explorer.

    Both support telemetry level 0=security. The endpoints connected (specific URLs) are probably different, though.

    Wow thanks for all the help guys!

    Another question i have is when did microsoft start the processor limiting?
    Im particularly interested in LTSB 2015 (1507) will it run a coffee lake cpu? Or has "new cpu prevention" already been implemented in this build?

    2015 LTSB got replaced pretty fast by 2016 LTSB, consider the latter to be the first.

    I don't think they are actively limiting them, like they are in Windows 7, they just don't officially support them if they come out after the OS build. I do know Ryzen 3 2200g and Ryzen 5 2600 work perfectly fine on LTSB if they are 'supported' or not. The telemetry is about the same in both and as mentioned both support telemetry level 0=security via gpedit (or registry change).

    Like Enthousiast said, 2015 came out and then got replaced pretty quickly. I never used it but it seems a little risky/pointless when the other two exist, unless there is something desirable about it that I just don't know? I'd go LTSB if you have a specific reason for it like if you hate Full Screen Optimization or something, and LTSC otherwise. LTSC is a little more 'bloaty' the first hour or two (more SPY-ON-ME=NO switches to throw), but after initial setup I think it is better.

    The only real problem I ever had with LTSC (but not LTSB) was with my Xonar SE sound card (but not the onboard Realtek), it had a weird audio micro stutter/dropout that happened every 20 seconds or so. It did not do it on LTSB 1607 or Full 1903. Since then I have gotten a new ASRock B450 Gaming K4 board and the problem stopped...so maybe it was a problem with the PCIe slots or BIOS/UEFI (like 4 of them) on my older MSI B450 Gaming Plus and not LTSC, or a weird mix of both. Never figured it out.

    Edit: About forced Windows Updates. LTSx has them too, though not as frequent. The cumulative updates, .NET and Flash Player stuff comes usually comes up once or twice a month. I've posted this somewhere before, but I use this method to completely stop all windows updates, until I am ready to install them. Each has an "On" and "Off" file for a convenient toggle with no third party tools required...usually needs a reboot to take effect.

    Copy to text file and name to whatyoulike.reg then just double click to use.

    Windows Updates Disabled.reg = it will "fail" even if you manually check
    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
    "DoNotConnectToWindowsUpdateInternetLocations"=dword:00000001
    "DisableWindowsUpdateAccess"=dword:00000001
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
    "UseWUServer"=dword:00000001
    
    
    Windows Updates Enabled.reg = default updates forced or manual
    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
    "DoNotConnectToWindowsUpdateInternetLocations"=-
    "DisableWindowsUpdateAccess"=-
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
    "UseWUServer"=-

    Could any of you guys point me to a 2015 ltsb (1507) iso? Im having trouble finding it, pherhaps a noobish mistake.

    I want to actually test it out.

    newer CPU architectures should work fine on older LTSx versions, even when not officially supported. (I personally use LTSB 2016 and a 9900K CPU)
    but if you are a gamer, it's different with graphics cards.. e.g. the pascal generation from nvidia needs at least LTSB 2016 und the turing generation even needs LTSC 2019.
