Set sound volume level on login

[Kasual]

Sometimes people set high (or max) volume level and forget to set volume to low on shut down.

After a few years of no activity at all, I'm "rusted" on windows customization.

Has anyone asked as a feature an option to set volume to a custom level on boot?

Sets Windows volume to a specified level before the welcome sound plays at boot. Works through a Windows service SetVolSvc that starts during the service loading phase — before winlogon and the shell. On first numeric input, the script downloads the NirCmd utility (nirsoft.net - 152KB), compiles the service volsvc.exe using the built-in Windows csc.exe compiler, and registers it via sc.exe. Subsequent inputs only update the volume in the service registry.

Input: 0–100 | Set volume: immediately + at every boot

Input: d | Full removal: stop and delete the SetVolSvc service, NirCmd folder, archive, HKCU:\...\Run entries, MUICache, Prefetch files

Input: q | Exit the script

Too much info
internet needed
How can I add it into windows unattended install image without internet set up?

Save the file as SetVolSvc.cmd with ANSI encoding.

No internet, no external tools, no NirCmd

Change volume: line 3 → set "VOL=30" (0–100)

Stops and removes the SetVolSvc service, deletes volsvc.exe and all related registry keys, restoring default Windows volume behavior (remembers last level set before shutdown):

cmd /c "sc stop SetVolSvc >nul 2>&1 & sc delete SetVolSvc >nul 2>&1 & del /f C:\Windows\System32\volsvc.exe >nul 2>&1 & reg delete HKLM\SYSTEM\CurrentControlSet\Services\SetVolSvc /f >nul 2>&1 & del /f C:\Windows\Prefetch\VOLSVC.EXE-*.pf >nul 2>&1 & echo removed"
