Please look at this example:
@echo off

REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1



! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum
1 REG_SZ ACPI\PNP0303\4&30647147&0

Press any key to continue . . .


@echo off

REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1

for /f "tokens=3" %%a in ('REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1 ^|findstr "REG_SZ"') do @set K1=%%a

echo %K1%

pause



! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum
1 REG_SZ ACPI\PNP0303\4&30647147&0

ACPI\PNP0303\4
'30647147' is not recognized as an internal or external command,
operable program or batch file.
'0' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .


How can I fix this error? Thanks!

Can't be helped, the forum categories seem a bit vague, since my question involves both DOS batch files and the Windows registry. It doesn't matter if points are deducted, take it as a lesson, but what I most hope for is that the problem can be solved.

It's all right. If I deducted points by mistake I can add them back to you.

Let's discuss what category your problem falls under. It's true that sometimes I also feel confused when using a DOS method to solve a Windows problem—is this a DOS problem or a Windows problem? But in your case I really can't see what it has to do with DOS.

If you want to solve similar problems with batch files in the future, you can post them in the "Batch File Room".

How should I put it? This is the discussion area, so it also seems reasonable for my question to be in 《DOSTroubleshooting & Problem Discussion (Answer Room) 》. Anyway, this isn't important. It doesn't matter if points were deducted. Could the administrator help solve this problem?


Also, do CMD commands belong to Windows or to DOS?]]>

As someone who registered around the time the forum was founded, and who has already reached the "Silver Member" level, seeing you ask a question like this really leaves me surprised.

I assume you must know willsort. If you're not clear on this concept, please take a look at his post:

http://www.cn-dos.net/forum/viewthread.php?tid=20682

Just read the first paragraph.

This article is written so well, just like the way he describes his own software. It's the first time I've come across it, and I've learned from it.
I registered in 2002, and Silver Member is actually not much. Earlier, because I forgot my password, I even registered another account called chishing. I forgot what rank that one was. Also, I'm not very active on this forum. I only think of coming here when I run into difficulties. Honestly speaking, the knowledge I've learned from this forum has helped me a great deal, and I also thank the enthusiastic moderators for answering my questions, thank you!
Actually, many of the forum's veteran members are probably like me, dropping by here from time to time whenever they go online, because sometimes the posts I reply to and the difficult questions I raise also take a long time before anyone responds.
I also admit I'm getting a bit older. It's not like I can use many commands or techniques whenever I want; I have to look at examples before I can write a program, just like flipping through a book during an open-book exam. Besides, DOS is only auxiliary for me. If I come up with a piece of software, could I really just know DOS and then write a program to sell? DOS can't do that.
Right now I'm also learning VBS. After all, under Windows its auxiliary value is greater than DOS's, and I've had a little success with it, but I still have to look things up before writing, because I can't remember it all.
I've said too much...

Back to the main topic, could the administrator help with the question in the top post?

Thanks to moderator HAT for the answer, but it still doesn't quite work, because the obtained value still has another use.
@echo off

REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1

for /f "tokens=3" %%a in ('REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1 ^|findstr "REG_SZ"') do @set K1=%%a

echo "%K1%"

pause


! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum
1 REG_SZ ACPI\PNP0303\4&30647147&0

"ACPI\PNP0303\4&30647147&0"
Press any key to continue . . .


Use the retrieved variable as part of a parameter and add a multi-string value:
REG ADD "HKLM,SYSTEM\CurrentControlSet\Enum\%K1%" /v UpperFilters /t  REG_MULTI_SZ /d BeTwinKeyboard


Error: Invalid key name
Press any key to continue . . .

Thanks! I think it should work, but I can't explain why clearly either—this key actually says access denied.

Yes, by default everyone has read permission on that branch. You can use the regini command to modify its permissions.

When I run regini directly nothing happens, and /? also gives no response. How do I modify the permissions?

As for the problem in the first post,
it seems this can also display normally:

@echo off&setlocal enabledelayedexpansion
REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1
for /f "tokens=3" %%a in ('REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\Kbdclass\Enum" /v 1 ^|findstr "REG_SZ"') do @set “K1=%%a”
echo !K1!
pause
endlocal
