InformationThis policy setting determines whether users can increase the base priority class of a process. (It is not a privileged operation to increase relative priority within a priority class.) This user right is not required by administrative tools that are supplied with the operating system but might be required by software development tools.
The recommended state for this setting is: Administrators.
A user who is assigned this user right could increase the scheduling priority of a process to Real-Time, which would leave little processing time for all other processes and could lead to a DoS condition.
SolutionTo establish the recommended configuration via GP, set the following UI path to Administrators:
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Increase scheduling priority
None - this is the default behavior.
On Windows Server 2016 or older: Administrators.
On Windows Server 2019 or newer: Administrators, Window Manager\Window Manager Group.
