If a device's hostname was recently changed, Splashtop will still display the old name. To fix this, simply run the script on your device, and the name will update in Splashtop.

IF EXIST "%PROGRAMFILES(X86)%" (GOTO 64BIT) ELSE (GOTO 32BIT)
:64BIT
reg add "HKLM\SOFTWARE\WOW6432Node\Splashtop Inc.\Splashtop Remote Server" /f /v CloudComputerName /t REG_SZ /d %computername%
GOTO END
:32BIT
reg add "HKLM\SOFTWARE\Splashtop Inc.\Splashtop Remote Server" /f /v CloudComputerName /t REG_SZ /d %computername%
GOTO END
:END
sc stop "SplashtopRemoteService"
sc start "SplashtopRemoteService"

You can upload the script to Atera and run it on your devices that have the issue. Please add the script as a Batch file (.bat) when uploading it to Atera.
