Batch file to backup WinMerge regsitry settings

[dcog989]

I created a batch file to backup the registry settings - thought someone else might find it useful:

1. create a file called winmerge-registry-backup.bat
2. edit and add the following code:

@echo off
REM This batch file will back up a specific location in the Windows registry.

REM Specify location:
set "registryKey=HKEY_USERS\S-1-5-21-413796706-13712985-2574880054-1000\Software\Thingamahoochie"

REM Get the current date and time in yyyymmdd-hhmmss format using PowerShell.
for /f %%I in ('powershell -NoProfile -Command "Get-Date -Format 'yyyyMMdd-HHmmss'"') do set "timestamp=%%I"

REM Define the location and filename for the backup file with timestamp.
set "backupFile=D:\Downloads\Winmerge-registry-%timestamp%.reg"

echo Backing up registry key: "%registryKey%" to "%backupFile%"

REM Use the reg export command to backup the registry key.
reg export "%registryKey%" "%backupFile%"

if errorlevel 1 (
    echo Error: Failed to backup the registry key.
    echo Please ensure you have the necessary permissions.
) else (
    echo Registry key backed up successfully to: "%backupFile%"
)

pause

3. double click the bat file to run it
