You getting error like "'adb' is not recognized as an internal or external command,operable program or batch file." has nothing to do with your admin rights.
Follow the steps:
- Go to folder location where your 'adb.exe' is located.
- copy the path and open cmd prompt and paste your folder location Example: C:\Users\298xxx>C:\Android\adt-bundle-windows-x86-20131030\adt-bundle-windows-x8 6-20131030\sdk\platform-tools\adb.exe
- Run any adb command you want like C:\Users\298xxx>C:\Android\adt-bundle-windows-x86-20131030\adt-bundle-windows-x86-20131030\sdk\platform-tools \adb.exe devices List of devices attached emulator-5554 device
Problem is that in machine you need to set path of ADB.exe in system properties but you didn't had access as admin which don't allowed you to open/work directly with system related things like install/uninstall/path setting and many more.
Another way to do the same is
- press ctrl+alt+del to open task manager
- Go to File --> New Task -- > and copy paste the path of you adb.exe (space) devices to check for devices attached to your machine.
