Introduced in Windows 10 version 1803, the Windows Activity history tracks a number of operations on the system: programs used, local files opened, SharePoint documents consulted, and websites browsed (using Internet Explorer / Microsoft Edge Legacy). The Activity history can be consulted in the Windows Timeline (Windows + Tab keys).

The ActivitiesCache.db is a SQLite database that locally stores the activity for its associated user.

The ActivitiesCache.db only stores data for the last 30 days by default.

Information of interest

The ActivitiesCache.db is composed of a number of tables, with the following tables being of interest:

  • Activity / ActivityOperation tables.

    • Data about various activities for different operation / activity type:
      • Program execution and opening of a file (5, ExecuteOpen)
      • Copy-pasting from a program (CopyPaste)
      • Application “in focus” (InFocus)
    • The data available depends on the activity type:
      • Start (startedDateTime) and end (lastActiveDateTime) timestamps of the activity (in UTC).
      • The activity ID (GUID).
      • Executable full path for program execution.
      • For certain programs, the accessed file name and path and / or associated SharePoint link.
      • Created and last modified timestamp of the associated file (local or on SharePoint).
      • The user’s device timezone.
    • An activity data can be present in either or both tables depending on the activity lifecycle. For example, a new activity will only be present in the Activity table, while an activity in the “upload queue” will be placed in the ActivityOperation table.
  • Activity_PackageId:

    • Data about the application(s) / program(s) linked to a specific activity (identified by its activity ID).

    • Data available:

      • The activity ID (GUID).
      • The application name / program filename.
      • Eventual program full path.
      • Activity expiration timestamp (timestamp of occurrence + 30 days by default).
  • Upon occurrence of an activity, one or multiple entries sharing the same activity ID will be created in the Activity_PackageId table, one for each program / application related to the activity.

Clipboard activity

The Activity / ActivityOperation tables reference clipboard activity through two activity types: 10 and 16. The events will be stored for approximately 12 hours after the operation.

The activity type 16 tracks use of the clipboard by an application, and is logged by default. The activity type 10 tracks the clipboard content, and is only logged if the non-default “Clipboard history” and “Sync across your devices” clipboard settings are both enabled. The later setting is only available for Microsoft or Azure AD synchronized accounts (and thus not available for local or simple Active Directory domain accounts).

If the pre-requisites are meet, an activity type 10 should be logged immediately after an activity type 16, allowing correlation of the two events.

The following information of interest is available for activity type 10 events:

  • The timestamp at which the data was copied (in the CreatedTime column, as an epoch timestamp).

  • The content of the clipboard, encoded in base64 (in the ClipboardPayload column).

The following information of interest is available for activity type 16 events:

  • The timestamp at which the data was copied (in the CreatedTime column, as an epoch timestamp).

  • The application from which the data was copied (in the AppId column).

  • If the data was copied (Copy) or pasted (Paste) (in the Group column). Only copy operation seem to generate an entry on recent versions of the Windows operating system however.


The WxTCmd utility (KAPE WxTCmd module) can parse and extract information from the ActivitiesCache.db database.
