The Hidden Administrator Account in Windows 10

During Windows 10 installation, a hidden administrator account has been set up. The hidden account is a super administrator which is good to use to troubleshoot and customize Windows. It is because the User Account Control (UAC) message would not be prompted while running special programs.

It's easy to enable/disable the hidden administrator account:

>> Run "Command Prompt" as administrator

To enable the hidden account : at the command prompt, type net user administrator /active:yes and press the Enter key. It will appear on the Windows 10 login screen

To disable the hidden account : at the command prompt, type net user administrator /active:no and press the Enter key.

Utilities for Managing Partitions

Sometimes, we need to perform partition tasks, for example regenerating the MBR, copying a disk, doing a disk surface test, allocating disk space etc. Operating systems provide built-in tools for creating, deleting, or resizing partitions. However, we would like to use third-party applications doing these types of tasks. Those applications might be easy to use and more flexible than the built-in partition tool. Here are several good partition manager utilities. Free editions are available.

1. AOMEI Partition Assistant
2. EaseUS Partition Master
3. Macrorit Disk Partition Expert
4. MiniTool Partition Wizard
5. Paragon Partition Manager
