Q:

Windows do not see adb devices in cmd

When I write in cmd adb devices I got from windows this:
'adb' is not recognized as an internal or external command,
operable program or batch file.

but in my 2nd pc when I write this same adb devices i got list of my devices and i see my phone with android.
What is wrong with 1st PC ? How to repair it ?

A:

It seems windows can't find adb in your computer. adb is located at this folder if you have installed android sdk
%USERPROFILE%\AppData\Local\Android\sdk\platform-tools

You can add this folder to PATH environment variable and then adb will be available globally. Here are steps
1. Click 'Start'.
2. Type 'Edit environment variables for your account', and click it.
3. Double click PATH.
4. Click 'New'.
5. Paste that path in.
6. Click 'OK', click 'OK', and restart any command prompts you have open.
