# Increase scheduling priority
|
||
|
||
**Applies to**
|
||
- Windows 10
|
||
|
||
Describes the best practices, location, values, policy management, and security considerations for the **Increase scheduling priority** security policy setting.
|
||
|
||
## Reference
|
||
|
||
This policy setting determines which user accounts 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 it might be required by software development tools.
|
||
|
||
Specifically, this security setting determines which accounts can use a process with Write Property access to another process to increase the run priority that is assigned to the other process. A user with this privilege can change the scheduling priority of a process through the Task Manager user interface.
|
||
|
||
Constant: SeIncreaseBasePriorityPrivilege
|
||
|
||
### Possible values
|
||
|
||
- User-defined list of accounts
|
||
- Not defined
|
||
- Administrators
|
||
|
||
### Best practices
|
||
|
||
- Allow the default value, Administrators, as the only account responsible for controlling process scheduling priorities.
|
||
|
||
### Location
|
||
|
||
Computer Configuration\\Windows Settings\\Security Settings\\Local Policies\\User Rights Assignment
|
||
|
||
### Default values
|
||
|
||
By default this setting is Administrators on domain controllers and on stand-alone servers.
|
||
|
||
The following table lists the actual and effective default policy values. Default values are also listed on the policy’s property page.
|
||
|
||
| Server type or GPO | Default value |
|
||
| - | - |
|
||
| Default Domain Policy| Not defined|
|
||
| Default Domain Controller Policy| Administrators|
|
||
| Stand-Alone Server Default Settings | Administrators|
|
||
| Domain Controller Effective Default Settings | Administrators|
|
||
| Member Server Effective Default Settings | Administrators|
|
||
| Client Computer Effective Default Settings | Administrators|
|
||
|
||
## Policy management
|
||
|
||
This section describes features, tools, and guidance to help you manage this policy.
|
||
|
||
A restart of the computer is not required for this policy setting to be effective.
|
||
|
||
Any change to the user rights assignment for an account becomes effective the next time the owner of the account logs on.
|
||
|
||
### Group Policy
|
||
|
||
Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:
|
||
|
||
1. Local policy settings
|
||
2. Site policy settings
|
||
3. Domain policy settings
|
||
4. OU policy settings
|
||
|
||
When a local setting is greyed out, it indicates that a GPO currently controls that setting.
|
||
|
||
## Security considerations
|
||
|
||
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
|
||
|
||
### Vulnerability
|
||
|
||
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 denial-of-service condition.
|
||
|
||
### Countermeasure
|
||
|
||
Verify that only Administrators have the **Increase scheduling priority** user right assigned to them.
|
||
|
||
### Potential impact
|
||
|
||
None. Restricting the **Increase scheduling priority** user right to members of the Administrators group is the default configuration.
