Is there Uninstall a program batch for windows?

to complement Bali's answer, try the following code...

@echo off
for /f "tokens=*" %%a in ('reg query hklm\software\Microsoft\Windows\CurrentVersion\Uninstall\ ^| find /I "%*"') do (
  for /f "tokens=1,2,*" %%b in ('reg query "%%a" /v UninstallString ^| find /I "UninstallString"') do (
    if /i %%b==UninstallString (
      echo %%d
    )
  )
)

test it carefully. And then remove the echo command.

There isn't really an uninstall command kind of thing in cmd that I know of. You could however query this reg key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

(might also need to check HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall if you're on a 64-bit machine)

to find the program you want to uninstall. Each one will have an UninstallString value which will tell you the path to the programs uninstaller file which you can then execute by calling it's full path and filename.

If the uninstaller happens to be an msi you can use

msiexec /uninstall /x to silently uninstall it. This is about as much as you can do with batch I think.

Hope this helps!

I wrote this this morning.

wmic product where name="%INPUT%" call uninstall
