Querying a registry key value via batch file

Question

I'm trying to create a simple batch file that uses the reg query command to check for the existence of a value in a registry key, specifically

HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings ProxyEnable key.

If I run this command:

reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /f 0x1 /d

It returns the following:

HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings ProxyEnable REG_DWORD 0x0

It's as if it's not accepting my /f search field, as I would expect the command as entered to return no results since my value for that key is 0x0 .

I've tried using quotes around the " 0x1 ", and other combinations, but wondering if I'm doing something wrong.

Thanks in advance!

Answer 1

As you only appear to be wanting to know if enabling proxy is toggled on, you can use this instead:

@Echo Off

Set "RR=HKCU"
Set "RK=Software\Microsoft\Windows\CurrentVersion\Internet Settings"
Set "RV=ProxyEnable"

For /F "Skip=1 Tokens=2*" %%A In ('Reg Query "%RR%\%RK%" /V "%RV%" 2^>Nul'
) Do If %%~B Gtr 0 Echo(%%B

Pause

If you wanted to for instance to toggle it on if it is off then change it to something like this:

@Echo Off

Set "RR=HKCU"
Set "RK=Software\Microsoft\Windows\CurrentVersion\Internet Settings"
Set "RV=ProxyEnable"

For /F "Skip=1 Tokens=2*" %%A In ('Reg Query "%RR%\%RK%" /V "%RV%" 2^>Nul'
) Do If %%~B Equ 0 Reg Add "%RR%\%RK%" /V "%RV%" /T REG_DWORD /D 0x1 /F>Nul

Although technically you could just run this to do that:

@Echo Off

Set "RR=HKCU"
Set "RK=Software\Microsoft\Windows\CurrentVersion\Internet Settings"
Set "RV=ProxyEnable"

Reg Add "%RR%\%RK%" /V "%RV%" /T REG_DWORD /D 0x1 /F>Nul

Edit

To check it first using the method suggested by Squashman and improved by zett42, because the following EnableHttp1_1 REG_DWORD 0x0 would have been sent to Find :

@Echo Off

Set "RR=HKCU"
Set "RK=Software\Microsoft\Windows\CurrentVersion\Internet Settings"
Set "RV=ProxyEnable"

Reg Query "%RR%\%RK%" /F 1 /E /T REG_DWORD|Find /I "%RV%">Nul 2>&1||(
    Reg Add "%RR%\%RK%" /V "%RV%" /T REG_DWORD /D 0x1 /F>Nul)

Answer 2

Reg query is for read registry data not for set or change the registry data
to change the Registry data replace query with Add

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable  /d 0x1 /f
