When you click the Share button in File Explorer’s Share tab, or invoke sharing option from a UWP app, the sharing pane opens on the right side of the screen displaying the list of apps with “Share target” support. To name a few, apps like Twitter, Mail and OneNote have this feature, and appear by default in the right pane.
Update (2021): The registry edit mentioned in this article no longer works in the latest Windows 10 releases (2004, 20H2, etc.)
For example, I can select Mail from the list and have the “screenshot (2).png” file sent to the Mail app as an attachment in the New Message or compose window automatically.
There is a new, hidden registry setting in Windows 10 using which you can configure which apps are listed, as well as limit the number of apps displayed in the Share pane.
Enable “Sharing Options” Page in Settings app
First, to enable the hidden “Share” options page in the Settings app, use these steps:
Start the Registry Editor (Regedit.exe) and go to:
HKEY_CURRENT_USER\Control Panel
Create a DWORD value named EnableShareSettings
Double-click EnableShareSettings and set its value data to 1
Exit the Registry Editor.
Access the Sharing Options Page
Close the Settings app and reopen it. Click System.
You’ll see a new category named “Share” at the bottom (after “About”).
Clicking “Share” opens the Sharing Options page where you can configure the following options:
- Show apps I use most often at the top of the app list
- Show a list of how I share most often
- Items in list (Minimum is 1 and maximum is 20)
You can also hide certain apps from being shown in the Share panel by turning off the radio button for individual apps listed under “Use these apps to share” section.
I’m disabling 3D Builder from the list…
It’s now hidden from the Share panel.
Tested in v1607 (Anniversary Update) and Creator’s Update Preview builds.
