List installed browsers

A simple script that reads the registry and lists installed browsers:

@echo off
START /W REGEDIT /E "%Temp%.\BROW.reg" HKEY_CURRENT_USER\Software\Classes

setlocal enableDelayedExpansion
for /f "tokens=4 delims=\" %%B in ('type %Temp%.\BROW.reg ^| findstr  /E  "HTML\shell]"') do (
 set "browser=%%B"
 echo !browser:~0,-4!
)
endlocal

del /Q /F "%Temp%.\BROW.reg"

It's from my answer in SO and the question looked interesting to me.

It reports Firefox in mine, but doesn't list MSIE.

The OP asked to list all browsers and also which one was default.

Yep,

Here's an improved version:

Code: Select all

@echo off
setlocal enableExtensions

echo.
echo.
echo INSTALLED BROWSERS
echo.
echo.

rem for 64 bit systems
START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet
set "bits=64"

rem for 32 bit systems
if not exist "%Temp%\BROW3.reg" (
  START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
  set "bits=32"
)

if "%bits%" equ "64" (
 for /f "tokens=6 delims=\" %%B in ('type "%Temp%\BROW3.reg"" ^| findstr /E "DefaultIcon]"') do (
   echo %%B
 )
)

if "%bits%" equ "32" (
  for /f "tokens=5 delims=\" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /E "DefaultIcon]"') do (
   echo %%B
 )
)
del /Q /F "%Temp%\BROW3.reg"

echo.
echo.
echo DEFAULT BROWSER
echo.
echo.

START /W REGEDIT /E "%Temp%\BROW4.reg" HKEY_CURRENT_USER\Software\Classes\webcal


for /f "tokens=* delims==@\0," %%B in ('type "%Temp%\BROW4.reg" ^| findstr /E ",0\"^"') do (
  echo %%~nB
)

del /Q /F "%Temp%\BROW4.reg"

In Windows 8 32 bit I get this:
"

INSTALLED BROWSERS

The syntax of the command is incorrect.

This registry key HKEY_CURRENT_USER\Software\Classes\webcal is not presented on all machines...(probably this gives the error)

The default browser value must be stored in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\HTTP\shell\open\command , but I'm not sure if it always returns the correct value.
I've tested this on VistaX64 and Windows XP Home Edition (X32) and works fine so far :

Code: Select all

@echo off
setlocal enableExtensions

echo.
echo.
echo INSTALLED BROWSERS
echo.
echo.

rem for 64 bit systems
START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet
set "bits=64"

rem for 32 bit systems
if not exist "%Temp%\BROW3.reg" (
  START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
  set "bits=32"
)

if "%bits%" equ "64" (
 for /f "tokens=6 delims=\" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /E "DefaultIcon]"') do (
   echo %%B
 )
)

if "%bits%" equ "32" (
  for /f "tokens=5 delims=\" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /E "DefaultIcon]"') do (
   echo %%B
 )
)
del /Q /F "%Temp%\BROW3.reg"

echo.
echo.
echo DEFAULT BROWSER
echo.
echo.

if "%bits%" equ "64" (
 START /W REGEDIT /E "%Temp%\BROW4.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\HTTP\shell\open\command
)
if "%bits%" equ "32" (
 START /W REGEDIT /E "%Temp%\BROW4.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\HTTP\shell\open\command
)


setlocal enableDelayedExpansion
for /f tokens^=3^ delims^=^" %%B in ('type "%Temp%\BROW4.reg" ^| find "@"') do (
	set "default=%%B"
	set "default=!default:\\=\!"
	set "default=!default:~0,-1!"
	for %%D in ("!default!") do echo %%~nD
)
endlocal
del /Q /F "%Temp%\BROW4.reg"
pause

Just for feedback I get this now. I haven't examined the code.

Hey, thanks for the feedback smile

To see what happens I'll need to see your exported registry files.
it seems the me that the registry nodes are with one less on your system (?)
This (at least the part that lists the browsers) should work on your machine:

Code: Select all

@echo off
setlocal enableExtensions

echo.
echo.
echo INSTALLED BROWSERS
echo.
echo.

rem for 64 bit systems
START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\StartMenuInternet


rem for 32 bit systems
if not exist "%Temp%\BROW3.reg" START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet

setLocal enableDelayedExpansion
for /f "tokens=*" %%B in ('type "%Temp%\BROW3.reg" ^| findstr /E "DefaultIcon]"') do (
  set "browser=%%B"
  set "browser=!browser:\DefaultIcon]=!"
  for %%P in ("!browser!") do echo %%~nP
)
endlocal

del /Q /F "%Temp%\BROW3.reg"

echo.
echo.
echo DEFAULT BROWSER
echo.
echo.

START /W REGEDIT /E "%Temp%\BROW4.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\HTTP\shell\open\command
if not exist "%Temp%\BROW4.reg"  START /W REGEDIT /E "%Temp%\BROW4.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\HTTP\shell\open\command
if not exist "%Temp%\BROW4.reg"   START /W REGEDIT /E "%Temp%\BROW3.reg" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\HTTP\shell\open\command


setlocal enableDelayedExpansion
for /f tokens^=3^ delims^=^" %%B in ('type "%Temp%\BROW4.reg" ^| find "@"') do (
	set "default=%%B"
	set "default=!default:\\=\!"
	set "default=!default:~0,-1!"
	for %%D in ("!default!") do echo %%~nD
)
endlocal
del /Q /F "%Temp%\BROW4.reg"
pause

At the moment I can't propose anything about the default browser... (it must be somewhere in HKEY_LOCAL_MACHINE\SOFTWARE\Classes)

One more attempt.Now I'm reading HKEY_CLASSES_ROOT\http\shell where the definitions should be more general. I've also added a check for default .html viewer .It is again tested on XP and Vista:

Thanks Giacomo for the info and link.

Your code is working for default browser and editor (I never edit html in IE - always my text editor) though the installed browser area is blank.

It's strange.I didn't change the part that lists installed browsers...
The default viewer is the program that opens the files with .html extension by default.It's not necessary to be for editing.
