Windows 10 LTSC 2021

12 more months until the official end of Win10 non-LTSC. Win10 22H2 (Enterprise, Home, Pro) ends 14 October 2025. Start your Windows 11 journey now, and maybe you'll have 50% of the bugs resolved or a workaround in place by next year >:}

Well here we are, 15th October 2025 and i reckon that interest in LTSC 2021(and the IoT version) will pick up so this is a little bump to remind people its here and for new users to see its here too. Can we expand the topic(and alter the thread title accordingly) to cover Windows 10 IoT Enterprise LTSC 2021 aswell because that is the one a lot of people are/will be interested in, :)

Got a laptop with LTSC 19044.4780 and bitlocker is turned off and another with 19044.6xxx and bitlocker is turned on. I hav'nt disabled bitlocker on .4780 but it is disabled nonetheless, what tweak in the registry disables it so i can export and use elsewhere?
 
Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BitLocker]
"PreventDeviceEncryption"=dword:00000001
 
Weird, i havnt got that in currentcontrolset or controlset001, all i have got is Control\BitLockerStatus\BootStatus = 0 in CCS and CS001.
 
W10 BitLocker won't automatically enable if your PC doesn't meet specific HW standards. W11 24H2 and later relaxed the standards.
 
Right, ok, so its a lottery whether it is enabled or disabled by default on a standard install, will try the tweak on the thinkpad(.4780) where it is enabled by default. Thank you.
 
It's not random.
BitLocker automatic device encryption is enabled when:
  • The device contains a TPM (Trusted Platform Module), either TPM 1.2 or TPM 2.0.
  • UEFI Secure Boot is enabled. See Secure Boot for more information.
  • Platform Secure Boot is enabled
  • Platform is Modern Standby or HSTI compliant (this requirement has been removed since Windows 11 24H2)
  • There are no un-allowed Direct memory access (DMA) interfaces (this requirement has been removed since Windows 11 24H2)
