Description of Desktop Icons

Question

I have succesfully altered the option on my Windows 10 desktop to make the system display certain facts about any icon when I hover over it - such as the source and date of the app to be run. I also noticed that for Microsoft icons (e.g. Microsoft Outlook) there is a verbal description of the use of the icon. I have created a lot of apps myself that I place on the Desktop and I would like to be able to add a description as well as the app source details. The source details can be seen.
I have found a reference in the Registry in HKCR\Local Settings\MuiCache\29f\417C44EB that has the identical description of the icon app, but with a coded key e.g @%windir%\system32\FXSRESM.dll,-115 has the data for Microsoft Outlook as follows "Send and receive faxes or scan pictures and documents." Other Icons use different DLL references.

The problem is that this reference does not say Microsoft Outlook anywhere - I guess the -115 means something. Is it possible to create some sort of method to give my own apps a description when I hover over them ?

Hi @Brian Johnson

You add your own descriptions to the app which is technically called tooltip.

A tooltip is a short description that is linked to another control or object. Tooltips help users understand unfamiliar objects that aren't described directly in the UI.

A ToolTip must be assigned to another UI element that is its owner. The ToolTipService class provides static methods to display a ToolTip.

Regarding the FXSRESM.dll it is a Microsoft Fax Resource DLL.FXSRESM.dll that creates new records and folders in the Windows registry.

Hope this resolves your Query!!
