Batch files to show the User/System environment variables stored in registry – via: Stack Overflow
Posted by jpluimers on 2016/09/20
I wrote two tiny batch files that would dump the environment variables from the registry.
Various reasons:
- Environment variables can be stored in two contexts: System and User (SET will show them all at once and for instance combine PATH up to 1920 characters).
- Environment variables can be set to auto-expand or not, which you cannot see from a SET command (REG_EXPAND_SZ versus REG_SZ).
show-user-environment-variables.bat:
reg query "HKCU\Environment"
show-system-environment-variables.bat:
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Filtered results:
