Create a pagefile - security policy setting
- Windows 10
Describes the best practices, location, values, policy management, and security considerations for the Create a pagefile security policy setting.
Windows designates a section of the hard drive as virtual memory known as the page file, or more specifically, as pagefile.sys. It is used to supplement the computer’s Random Access Memory (RAM) to improve performance for frequently used programs and data. Although the file is hidden from browsing, you can manage it using the system settings.
This policy setting determines which users can create and change the size of a page file. It determines whether users can specify a page file size for a particular drive in the Performance Options box located on the Advanced tab of the System Properties dialog box or through using internal application interfaces (APIs).
- User-defined list of accounts
- Restrict the Create a pagefile user right to Administrators, which is the default.
Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment
By default, members of the Administrators group have this right.
The following table lists the actual and effective default policy values for the most recent supported versions of Windows. Default values are also listed on the policy’s property page.
|Server type or GPO||Default value|
|Default Domain Policy||Administrators|
|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|
A restart of the device 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.
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:
- Local policy settings
- Site policy settings
- Domain policy settings
- OU policy settings
When a local setting is greyed out, it indicates that a GPO currently controls that setting.
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.
Users who can change the page file size could make it extremely small or move the file to a highly fragmented storage volume, which could cause reduced device performance.
Restrict the Create a pagefile user right to members of the Administrators group.
None. Restricting this right to members of the Administrators group is the default configuration.
