Question:
I would like to export multiple registry keys to the same .reg file. Every suggestion I’ve seen shows to use reg /e [key name] filename.reg, but I have a list of 4-5 registry entries I want to export and doing it this way will overwrite it each time.
What I want is something like:
- Export HKLM\Software\Test\ABC RegFile.reg
- Export HKLM\Software\ABC\123 RegFile.reg
- Export HKLM\Software\XYZ\Lala RegFile.reg
So that each registry key is appended to the same .reg file, not overwritten each time. How can I do this?
Answer:
The simplest way would be to export each key individually, and then merge the resulting files:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
$keys = 'HKLM\Software\Test\ABC', 'HKLM\Software\ABC\123', ... $tempFolder = 'C:\temp\folder' $outputFile = 'C:\path\to\merged.reg' $keys | % { $i++ & reg export $_ "$tempFolder\$i.reg" } 'Windows Registry Editor Version 5.00' | Set-Content $outputFile Get-Content "$tempFolder\*.reg" | ? { $_ -ne 'Windows Registry Editor Version 5.00' } | Add-Content $outputFile |
