User Account Control (UAC)

Permissions

Access to files, folders, and printers is controlled through permissions. Permissions identify what the user can do with the associated object.

Administrators

Members of the Administrators group have complete and unrestricted access to the computer, including every system right. The Administrator user account and any other account designated as a "computer administrator" is a member of this group.

Backup Operators

Members of the Backup Operators group can back up and restore files (regardless of permissions), log on locally, and shut down the system. Members of this group cannot change security settings.

Cryptographic Operators

Members of the Cryptographic Operators group are allowed to perform cryptographic operations.

Event Log Readers

Members of the Event Log Readers group are allowed to use Event Viewer to read the system's event logs.

Guests

Members of the Guests group have limited rights (similar to members of the Users group). Members can shut down the system.

Hyper-V Administrators

Members of the Hyper-V Administrators group are allowed to use Hyper-V on the system to create and manage virtual machines.

Network Configuration Operators

Members of the Network Configuration Operators group have limited administrative privileges to allow them to manage the system's network configuration.

Performance Log Users

Members of the Performance Log Users group are allowed to schedule logging of performance counters, enable trace providers, and collect event traces on the system.

Performance Monitor Users

Members of the Performance Monitor Users group can access performance counter data on the system.

Remote Desktop Users

Members of the Remote Desktop Users group are allowed to access the system remotely using the Remote Desktop Client.

Users

Members of the Users group can use the computer but cannot perform system administration tasks and might not be able to run some legacy applications. Members cannot share folders. Members cannot install printers if the driver isn't already installed on the system. Members cannot view or modify system files. Any user created with Local Users and Groups is automatically a member of this group. User accounts designated as "standard" or "limited use" accounts are members of this group. A user account created as a "computer administrator" is made a member of this group (in addition to being a member of the Administrators group).

Power Users

Modern versions of Windows no longer use the Power Users group, although it still exists for backwards compatibility. This group was originally used in Windows XP and earlier. Its members can: Create user accounts Modify or delete accounts they created Create local groups Modify group membership for groups they created Modify group membership for the Power Users, Users, and Guests groups Change the system date and time Install applications Power Users were not allowed to: Change membership of the Administrators or Backup Operators groups Take ownership of files Back up or restore files Load or unload device drivers Manage security and auditing logs In modern versions of Windows, you should avoid assigning users to be members of the Power Users group unless an application or service specifically requires it.

Groups

Rights and permissions can be assigned to multiple users through groups.

Microsoft Accounts

User Account

The ability to use a computer is controlled through a user account. The user account identifies a specific user.

On Windows systems, the ability to perform actions on a computer, such as modifying system settings or installing hardware, are called rights. Access to files, folders, and printers is controlled through permissions. Permissions identify what the user can do with the associated object. Windows 10 offers five basic types of user accounts: the built-in Administrator account, user accounts with administrative privileges, standard accounts, the Guest account, and Microsoft accounts. You can manage users from the Accounts setting. Go to Accounts by following these steps: Select Start. Select Settings. Select Accounts. The table below shows capabilities of each account.

Guest Account
