How can we insert multiple keys into a registry folder without using 3rd party tools?

Solution 1:

Using built in tools on Windows you have a few options.

1. Use the regedit GUI.

Microsoft regedit provides import and export [export visible in your screenshot] options. When you export a key, it will appear in a .REG file. This is an example.

example.reg

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Example]
[HKEY_CURRENT_USER\SOFTWARE\Example\keyA]
"value0"=dword:00000000
"value1"="data"

To import open regedit, use the menu and navigate File -> Import, then select the .REG file.

2. Use the reg command line utility.

The reg utility also provides import and export options. To perform the same steps as above, you would do something like.

:: Export
REG EXPORT HKCU\SOFTWARE\example\ example.reg

:: Import
REG IMPORT example.reg

You can also write keys/values/data ad-hoc with reg.

REG ADD "HKCU\SOFTWARE\example\keyA" /v "value0" /t REG_DWORD /d "0" /f
REG ADD "HKCU\SOFTWARE\example\keyA" /v "value1" /t REG_SZ /d "data" /f

3. Use a Group Policy Registry Preference item.

Use gpmc.msc to configure a Group Policy Registry Preference and deploy it as needed.

Solution 2:

In addition to jscott's response, powershell can natively manage the registry.
