Version Notes
LTSC 1809
Has both curl.exe and tar.exe
Defrag command in Maintenance bat needs different flags than 21H2
No known benefit over 21H2
LTSB 1607
No curl.exe nor tar.exe
Runs GTA V Online (BattlEye no problem 1607, GTA V DX10 fine 2018 GPU driver)
Intel UHD 630 driver from 2018 (.2141 nor latest 6th-gen install/require newer Windows than 1607)
OneDrive is integrated and doesn't uninstall as-easily like it's installed with Office
No Edge (business msi installs fine and works with msedge_proxy)
Alps touchpad driver doesn't install (benefit)
