| String ID | String Text |
|---|---|
| 1 | Whether Application Launch Prefetching is enabled |
| 2 | Whether Operation API Prefetching Functionality is enabled |
| 3 | Whether Page Combining is enabled |
| 4 | Whether Application PreLaunch is enabled |
| 5 | The maximum number of prefetch files for scenarios recorded by the Operation Recorder API |
| 6 | Memory Management Agent Component Configuration |
| 7 | Provides the capability to enable any combination of the following: 1. Application Launch Prefetching 2. Operation API Prefetching Functionality 3. Page Combining 4. Application PreLaunch |
| 8 | Whether to enable Application Launch Prefetching. Application launch prefetching would would speed up app startup by monitoring the data and code accessed in these cases and use that information to preload the data and code into physical memory for subsequent app startups |
| 9 | Whether to enable Operation Recorder API Functionality. Operation Recorder enables applications to speed up operations that repeatedly access the same file data by exposing the Windows prefetching mechanism as a public interface. |
| 10 | Whether to enable Page Combining. Page Combining helps reduce the physical memory usage of the operating system by periodically combining pages in physical memory that have identical content. |
| 11 | Whether to enable Application PreLaunch. Application PreLaunch can speculatively launch applications that the user is likely to use in the near future, thus reducing application switch time. |
| 12 | Provides the ability to set the maximum number of prefetch files for scenarios recorded by the Operation Recorder API. |
| 13 | Returns whether any combination of the following are enabled: 1. Application Launch Prefetching 2. Operation API Prefetching Functionality 3. Page Combining 4. Application PreLaunch and also returns the maximum number of prefetch files for scenarios recorded by the Operation Recorder API. |
| 14 | The set of components enabled and the maximum number of prefetch files for scenarios recorded by the Operation Recorder API. |
| 15 | Provides the capability to disable any combination of the following: 1. Application Launch Prefetching 2. Operation API Prefetching Functionality 3. Page Combining 4. Application PreLaunch |
| 16 | Whether to disable Application Launch Prefetching. Application launch prefetching would would speed up app startup by monitoring the data and code accessed in these cases and use that information to preload the data and code into physical memory for subsequent app startups |
| 17 | Whether to disable Application PreLaunch. Application PreLaunch can speculatively launch applications that the user is likely to use in the near future, thus reducing application switch time. |
| 18 | Whether to disable Operation Recorder API Functionality. Operation Recorder enables applications to speed up operations that repeatedly access the same file data by exposing the Windows prefetching mechanism as a public interface. |
| 19 | Whether to disable Page Combining. Page Combining helps reduce the physical memory usage of the operating system by periodically combining pages in physical memory that have identical content. |
| 20 | Provides the ability to debug the application prelaunch of a specific application by triggering the prelaunch to occur and to exit debug mode for the application. |
| 21 | Specifies the package full name of the application. |
| 22 | If this parameter is specified, the specified application will no longer be in debug mode. If not specified, the application will be prelaunched in debug mode. |
| 23 | Specifies the string identifying the app in the package. |
| 24 | Memory Management Agent |
| 207 | Unknown |
| 1000 | Superfetch |
| 1001 | Maintains and improves system performance over time. |
