CreateObjectTask under CloudExperienceHost.Microsoft-Windows-DiskDiagnosticDataCollector under DiskDiagnostic.all items under Application Experience, Autochk and Customer Experience Improvement Program.In the left-hand menu, open Task Scheduler (local) -> Task Scheduler Library -> Microsoft -> Windows and disable the following entries: Open Control Panel -> Administrative Tools ->Task Scheduler. We need to disable some tasks scheduled by Windows as they collect data and send it to Microsoft. Type the following commands into the command prompt:Įcho "" > C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl Open Start menu, type cmd, right-click and Run as Administrator. There are a couple of services responsible for data collection. If you have removed the updates from the Step 3, you won’t need to disable the services in this step. Feel free to remove and disable those updates so they won't be installed in the future. We have already published an update removal guide. Open Control Panel -> Action Center -> Change Action Center settings.Īt the bottom of the window, click Customer Experience Improvement Program settings and choose No, I don't want to participate in the program. You can opt-out of this data collection program. Windows 7 offers users to participate in user activity research by Microsoft. While all the actions listed herein are pretty much safe, creating a system restore point won’t hurt. This guide will explain how to disable some system options to prevent certain data collection by Microsoft. We have already described which updates can be removed from Windows 7 and 8.1 for privacy concerns in a separate guide. While the problem isn't that big, it’s still there on Windows 7 and 8.1. However, this kind of conservatism doesn't make much sense. Still, some people stick to Windows 7 or 8.1 for the sake of privacy. We accomplish the goal of heap logging by using the HeapGuid as the session instance guid.Windows 10 has tons of nice features. This value copied from GlobalLogger, where it was set based on -stackwalk VirtualAlloc+HeapCreate+HeapAlloc+HeapRealloc If we leave it blank, then "xperf -loggers" shows it set to 100. That will cause xperf to fail when trying to merge. Default (if we leave absent) is 100 (MB) and after that the trace session is shut down. Setting it to sequential is sufficient - EVENT_TRACE_DELAY_OPEN_FILE_MODE and EVENT_TRACE_ADD_HEADER_MODE are not needed. #define EVENT_TRACE_USE_PAGED_MEMORY 0x01000000 // Use pageable buffers #define EVENT_TRACE_RELOG_MODE 0x00010000 // Relogger #define EVENT_TRACE_USE_LOCAL_SEQUENCE 0x00008000 // Use local sequence no. #define EVENT_TRACE_USE_GLOBAL_SEQUENCE 0x00004000 // Use global sequence no. #define EVENT_TRACE_ADD_HEADER_MODE 0x00001000 // Add a logfile header #define EVENT_TRACE_PRIVATE_LOGGER_MODE 0x00000800 // Process Private Logger #define EVENT_TRACE_BUFFERING_MODE 0x00000400 // Buffering mode only #define EVENT_TRACE_DELAY_OPEN_FILE_MODE 0x00000200 // Delay opening file #define EVENT_TRACE_REAL_TIME_MODE 0x00000100 // Real time mode on #define EVENT_TRACE_FILE_MODE_APPEND 0x00000004 // Append sequential log #define EVENT_TRACE_FILE_MODE_CIRCULAR 0x00000002 // Log in circular manner #define EVENT_TRACE_FILE_MODE_SEQUENTIAL 0x00000001 // Log sequentially #define EVENT_TRACE_FILE_MODE_NONE 0x00000000 // Logfile is off See etw\tracesub.c, ValidModeMask for a list of all valid bits. Default LogFileMode = EVENT_TRACE_FILE_MODE_SEQUENTIAL | _DELAY_OPEN_FILE_MODE | _ADD_HEADER_MODE but in order to turn on heap tracing it *MUST* be the HeapGuid, NOTE: You might think the Guid could be any value to identify the session uniquely, The accompanying example shows how to set the appropriate registry values. When AutoLogger is used in conjunction with WPA On/Off Transition Trace Capture, also referred to as xbootmgr, information can be collected during the on/off transition phases of the operating system. AutoLogger can turn on heap tracing at boot time.
