SAC is included in all versions of Windows since Windows Server 2003. By default, however, it's disabled. SAC relies on the `sacdrv.sys` kernel driver, the `Special Administration Console Helper` service (`sacsvr`), and the `sacsess.exe` process. For more information, see [Emergency Management Services Tools and Settings](/previous-versions/windows/it-pro/windows-server-2003/cc787940(v%3dws.10)).

SAC enables you to connect to your running OS through a serial port. When you open a Command Prompt window in SAC, `sacsess.exe` starts `cmd.exe` within your running OS. In Task Manager, you can see that if you connect through RDP to your VM at the same time as you're connected to SAC through the serial console feature. The CMD window that you access through SAC is the same as the `cmd.exe` window that you use when you connect through RDP. All the same commands and tools are available, including the ability to start PowerShell from that CMD instance. The major difference between SAC and the Windows Recovery Environment (WinRE) is that SAC lets you manage your running OS, but WinRE starts up into a different, minimal OS. Although Azure VMs don't support the ability to access WinRE, they can be managed through SAC.

Because SAC is limited to an 80x24 pixel screen buffer that has no scroll back capability, add `| more` to commands to display the output one page at a time. Use `<spacebar>` to see the next page, or `<enter>` to see the next line.
