从批处理中编辑Windows注册表中的多类型项

Question

Task - set default display resoltuion for all "Displays".

But - in registry is three of them:

HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{F92BFB9B-59E9-4B65-8AA3-D004C26BA193}\0000

HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{2D5BA881-99A8-4757-A06E-CB5493B97A39}\0000

HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{0F8D6C53-C039-4908-839F-1494115035F7}\0000

Need to edit entry in 0000 , but how it can be done from batch script?

If add * symbol - it's create new key.

Here is script content:

C:\Users\user\Documents>type reg.bat
REGEDIT4

; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT

[HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{*}\000]
"TestVal"="TestVal"

So - result is:

HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{*}\000

What is correct way to do it?

Answer 1

This will enumerate all the keys under VIDEO and then add the Value and Data to each 0000 key.

for /f "delims=" %%A in ('reg query "HKCC\System\CurrentControlSet\Control\VIDEO"') do reg add "%%~A\0000" /v TestVal /t REG_SZ /d "TestVal" /f

See the help text for details about each command.

• for /?
• reg query /?
• reg add /?
