Specify default quota limit and warning level
This policy setting specifies the default disk quota limit and warning level for new users of the volume. This policy setting determines how much disk space can be used by each user on each of the NTFS file system volumes on a computer. It also specifies the warning level the point at which the user’s status in the Quota Entries window changes to indicate that the user is approaching the disk quota limit. This setting overrides new users’ settings for the disk quota limit and warning level on their volumes and it disables the corresponding options in the “Select the default quota limit for new users of this volume” section on the Quota tab. This policy setting applies to all new users as soon as they write to the volume. It does not affect disk quota limits for current users or affect customized limits and warning levels set for particular users (on the Quota tab in Volume Properties). If you disable or do not configure this policy setting the disk space available to users is not limited. The disk quota management feature uses the physical space on each volume as its quota limit and warning level. When you select a limit remember that the same limit applies to all users on all volumes regardless of actual volume size. Be sure to set the limit and warning level so that it is reasonable for the range of volumes in the group. This policy setting is effective only when disk quota management is enabled on the volume. Also if disk quotas are not enforced users can exceed the quota limit you set. When users reach the quota limit their status in the Quota Entries window changes but users can continue to write to the volume.
Enforce disk quota limit
This policy setting determines whether disk quota limits are enforced and prevents users from changing the setting. If you enable this policy setting disk quota limits are enforced. If you disable this policy setting disk quota limits are not enforced. When you enable or disable this policy setting the system disables the “Deny disk space to users exceeding quota limit” option on the Quota tab so administrators cannot make changes while the setting is in effect. If you do not configure this policy setting the disk quota limit is not enforced by default but administrators can change the setting. Enforcement is optional. When users reach an enforced disk quota limit the system responds as though the physical space on the volume were exhausted. When users reach an unenforced limit their status in the Quota Entries window changes but they can continue to write to the volume as long as physical space is available. Note: This policy setting overrides user settings that enable or disable quota enforcement on their volumes. Note: To specify a disk quota limit use the “Default quota limit and warning level” policy setting. Otherwise the system uses the physical space on the volume as the quota limit.
Enable disk quotas
This policy setting turns on and turns off disk quota management on all NTFS volumes of the computer and prevents users from changing the setting. If you enable this policy setting disk quota management is turned on and users cannot turn it off. If you disable the policy setting disk quota management is turned off and users cannot turn it on. If this policy setting is not configured disk quota management is turned off by default but administrators can turn it on. To prevent users from changing the setting while a setting is in effect the system disables the “Enable quota management” option on the Quota tab of NTFS volumes. Note: This policy setting turns on disk quota management but does not establish or enforce a particular disk quota limit. To specify a disk quota limit use the “Default quota limit and warning level” policy setting. Otherwise the system uses the physical space on the volume as the quota limit. Note: To turn on or turn off disk quota management without specifying a setting in My Computer right-click the name of an NTFS volume click Properties click the Quota tab and then click “Enable quota management. “
Turn off solid state mode
This policy setting turns off the solid state mode for the hybrid hard disks. If you enable this policy setting frequently written files such as the file system metadata and registry may not be stored in the NV cache. If you disable this policy setting the system will store frequently written data into the non-volatile (NV) cache. This allows the system to exclusively run out of the NV cache and power down the disk for longer periods to save power. Note that this can cause increased wear of the NV cache. If you do not configure this policy setting the default behavior of the system is observed and frequently written files will be stored in the NV cache. Note: This policy setting is applicable only if the NV cache feature is on.
Turn off non-volatile cache feature
This policy setting turns off all support for the non-volatile (NV) cache on all hybrid hard disks in the system. To check if you have hybrid hard disks in the system from Device Manager right-click the disk drive and select Properties. The NV cache can be used to optimize boot and resume by reading data from the cache while the disks are spinning up. The NV cache can also be used to reduce the power consumption of the system by keeping the disks spun down while satisfying reads and writes from the cache. If you enable this policy setting the system will not manage the NV cache and will not enable NV cache power saving mode. If you disable this policy setting the system will manage the NV cache on the disks if the other policy settings for the NV cache are appropriately configured. Note: This policy setting will take effect on next boot. If you do not configure this policy setting the default behavior is to turn on support for the NV cache.
Turn off cache power mode
This policy setting turns off power save mode on the hybrid hard disks in the system. If you enable this policy setting the hard disks are not put into NV cache power save mode and no power savings are achieved. If you disable this policy setting the hard disks are put into an NV cache power saving mode. In this mode the system tries to save power by aggressively spinning down the disk. If you do not configure this policy setting the default behavior is to allow the hybrid hard disks to be in power save mode. Note: This policy setting is applicable only if the NV cache feature is on.
Turn off boot and resume optimizations
This policy setting turns off the boot and resume optimizations for the hybrid hard disks in the system. If you enable this policy setting the system does not use the non-volatile (NV) cache to optimize boot and resume. If you disable this policy setting the system uses the NV cache to achieve faster boot and resume. The system determines the data that will be stored in the NV cache to optimize boot and resume. The required data is stored in the NV cache during shutdown and hibernate respectively. This might cause a slight increase in the time taken for shutdown and hibernate. If you do not configure this policy setting the default behavior is observed and the NV cache is used for boot and resume optimizations. Note: This policy setting is applicable only if the NV cache feature is on.
Specify the search server for device driver updates
This policy setting allows you to specify the search server that Windows uses to find updates for device drivers. If you enable this policy setting you can select whether Windows searches Windows Update (WU) searches a Managed Server or a combination of both. Note that if both are specified then Windows will first search the Managed Server such as a Windows Server Update Services (WSUS) server. Only if no update is found will Windows then also search Windows Update. If you disable or do not configure this policy setting members of the Administrators group can determine the server used in the search for device drivers.
Specify search order for device driver source locations
This policy setting allows you to specify the order in which Windows searches source locations for device drivers. If you enable this policy setting you can select whether Windows searches for drivers on Windows Update unconditionally only if necessary or not at all. Note that searching always implies that Windows will attempt to search Windows Update exactly one time. With this setting Windows will not continually search for updates. This setting is used to ensure that the best software will be found for the device even if the network is temporarily available. If the setting for searching only if needed is specified then Windows will search for a driver only if a driver is not locally available on the system. If you disable or do not configure this policy setting members of the Administrators group can determine the priority order in which Windows searches source locations for device drivers.
Disk Diagnostic: Configure execution level
This policy setting determines the execution level for S. M. A. R. T. -based disk diagnostics. Self-Monitoring And Reporting Technology (S. M. A. R. T. ) is a standard mechanism for storage devices to report faults to Windows. A disk that reports a S. M. A. R. T. fault may need to be repaired or replaced. The Diagnostic Policy Service (DPS) detects and logs S. M. A. R. T. faults to the event log when they occur. If you enable this policy setting the DPS also warns users of S. M. A. R. T. faults and guides them through backup and recovery to minimize potential data loss. If you disable this policy S. M. A. R. T. faults are still detected and logged but no corrective action is taken. If you do not configure this policy setting the DPS enables S. M. A. R. T. fault resolution by default. This policy setting takes effect only if the diagnostics-wide scenario execution policy is not configured. No reboots or service restarts are required for this policy setting to take effect: changes take effect immediately. This policy setting takes effect only when the DPS is in the running state. When the service is stopped or disabled diagnostic scenarios are not executed. The DPS can be configured with the Services snap-in to the Microsoft Management Console. Note: For Windows Server systems this policy setting applies only if the Desktop Experience optional component is installed and the Remote Desktop Services role is not installed.
