How to Exclude Items from Taskbar Pinning and Recent/Frequent Lists

Applications, processes, and windows can opt to make themselves unavailable for pinning to the taskbar or for inclusion in the Start menu's Most Frequently Used (MFU) list.


There are three mechanisms to accomplish the exclusion of items from taskbar pinning and recent/frequent lists:

  • Add the NoStartPage entry to the application's registration as shown in this example:


    The data associated with the NoStartPage entry is ignored. Only the presence of the entry is required. Therefore, the ideal type for NoStartPage is REG_NONE.

    Note that any use of an explicit Application User Model ID (AppUserModelID) overrides the NoStartPage entry. If an explicit AppUserModelID is applied to a shortcut, process, or window, it becomes pinnable and eligible for the Start menu MFU list.

  • Set the System.AppUserModel.PreventPinning property on windows and shortcuts. This property must be set on a window before the PKEY_AppUserModel_ID property is set.

  • Add an explicit AppUserModelID as a value under the following registry subkey as shown in this example:

HKEY_LOCAL_MACHINE    Software       Microsoft          Windows             CurrentVersion                Explorer                   FileAssociation                      NoStartPageAppUserModelIDs                         AppUserModelID1                         AppUserModelID2                         AppUserModelID3

Each entry is a **REG\_NULL** value with the name of the AppUserModelID. Any AppUserModelID that is found in this list is not pinnable and not eligible for inclusion in the **Start** menu MFU list.


Be aware that certain executable files, as well as shortcuts that contain certain strings in their names, are automatically excluded from pinning and inclusion in the MFU list.

Note  This automatic exclusion can be overridden by applying an explicit AppUserModelID.


If any of the following strings, regardless of case, are included in the shortcut name, the program is not pinnable and is not displayed in the most frequently used list:

  • Documentation
  • Help
  • Install
  • More Info
  • Read me
  • Read First
  • Readme
  • Remove
  • Setup
  • Support
  • What's New

The following list of programs are not pinnable and are excluded from the most frequently used list:

  • Applaunch.exe
  • Control.exe
  • Dfsvc.exe
  • Dllhost.exe
  • Guestmodemsg.exe
  • Hh.exe
  • Install.exe
  • Isuninst.exe
  • Lnkstub.exe
  • Mmc.exe
  • Mshta.exe
  • Msiexec.exe
  • Msoobe.exe
  • Rundll32.exe
  • Setup.exe
  • St5unst.exe
  • Unwise.exe
  • Unwise32.exe
  • Werfault.exe
  • Winhlp32.exe
  • Wlrmdr.exe
  • Wuapp.exe

The preceding lists are stored in the following registry values.

Note  These lists should not be modified by applications. Use one of the exclusion list methods described earlier in this topic for the same experience.
