We noticed that: Shortcut is created on desktop if standard users select 'No' at UAC.

How does a standard user select "Yes" for the UAC prompt? Does that mean providing a different username/password?

When prompted with the UAC the Standard user has a chance to select Yes if provided with admin credentials (user/pass, or pin for admin account, depending on how the admin account is set up) so that the program would install in its default admin path C:\Program Files\Firefox Nightly\. Selecting "No" or closing the prompt will install Firefox in C:\Users\<user>\AppData\Local\Firefox Nightly\

OK, that makes sense.

When you select "Yes" for the UAC prompt, is the Desktop Launcher installed into the admin user's Desktop folder?

Indeed it is, yes.

I've asked in Slack if this is needed for Fx146

Attachment: Bug 1982323 - Create and remove the desktop launcher from the desktop of the user who initially ran the installer. r=cdupuis!

The uninstaller half should 'work', but doesn't fix anything yet---
if I recall, UAC::ExecCodeSegment doesn't do anything there right now, so
we're no further ahead. The installer half should work, though.

[Duncan McIntosh [:dmcintosh]]

Cleaning up a needinfo, this uh slightly missed Fx146.

Installing the shortcut is easy enough (UAC::ExecCodeSegment should do it), but removing the shortcut is harder. The uninstaller for whatever reason has a multi-step process: it elevates to admin, writes (from helper.exe) a temporary uninstaller, then runs it. That means that UAC::ExecCodeSegment just thinks we're the admin, so we're no further ahead.

This might not be too hard to tweak, I'll keep myself assigned for now...
