Internally, there was another egg, where several internal system functions (although having meaningful internal names) were exported from user.exe as BEAR NNN (where NNN is the ordinal number of the function) in his honor and to discourage their use by third-party software developers.

The other one was a reference to a fictitious file named BEAR.EXE in the properties window for the MS-DOS Prompt. bradsi, being in charge of Windows production, is listed first the three other presenters, billg, steveb, and t-bear, appear together in ' Special Thanks', the last section of the list. One was the developer credits, where the Bear, along with Bill Gates, Steve Ballmer, and Brad Silverberg, present the email aliases of the Windows 3.1 developers. Windows 3.1 has two visible Easter eggs, both of which reference the Microsoft Bear, which was the mascot of the Windows 3.1 development team. This causes the developer credits to appear on the desktop in the form of the email names of the crew. Windows 3.0 has a developer credits page which may be accessed by setting the focus to the desktop (by minimizing all windows and clicking on an open area of the desktop) then typing win30 followed by F3 and ← Backspace in quick succession. 2.0 and later: Press F1, F5, F9, F4 and ← Backspace in rapid succession.

1.01 and later: Hold Alt then Esc, release Alt then Esc, press Esc twice then press ← Backspace.

1.xx: Press Alt+ ⇧ Shift+ Esc+ ↵ Enter.

The instructions for invoking the Easter egg vary depending on the version: Double clicking the list box further changes the background of the window to tiled smiley faces. Windows 1.0, 2.0 and 2.1 all include an Easter egg which features a window that shows a list of people who worked on the software along with a 'Congrats!' button.
