Microsoft understands how important your computer is, and provides you with Installation DVD disk to bypass the lost password and regain access to Windows Server 2019. If you have such a disk at hand, you're lucky enough.

Here's everything you need to know about resetting forgotten Windows 2019 Server password using installation CD.

• • Insert the installation DVD into your Windows Server 2019 computer.
  • Start the machine and press key (F2, F1, ESC, etc) to enter BIOS SETUP utility. Use the arrow key to select the DVD as first boot order and hit Enter.
  • After your computer boots from the disc, select your language and keyboard and then Next.
  • Select Repair your computer at the lower left corner.
  • Select Troubleshoot and then choose Command Prompt.
  • Execute the following two commands, and press Enter after each.

• • Remove the disc and run command wpeutil reboot to restart your computer.
  • When login screen appears, click Ease of Access icon at the lower right corner (or Windows Key + U) to open a Command Prompt.
  • Execute the net user command as shown to reset the Windows Server 2019 Administrator password. Replace Appgeeker with whatever new password you want.
