One of the "advanced features' of Windows 10 is that it no longer supports many convenient workarounds to which you have become accustomed. The easiest thing to do would be to create a shortcut that points to the indicated folder and either leave it on your desktop or copy it to the Start menu. Go to StartButton->ExploreAllUsers, navigate so that the indicated folder is in the RIGHT-HAND PANEL, then click once, right-click once, and choose CreateShortcut. You can move this shortcut to the desktop or attach it to the Start menu.
If you have trouble dragging and dropping to the Start menu, note that the Start menu is also available through Windows Explorer (that is, through ExploreAllUsers). It acts just like any folder, with the individual menu icons appearing as entires (files, shortcuts, links) in that folder.
The only way to do this would be to use Windows Explorer (Start->ExploreAllUsers) and hunt for the StartMenu or All Programs in Windows Explorer. If it's not easy to find, pull up a DOS command prompt, cd to \, and type the command dir /s /b AllPrograms*.*
Once you have found it, you can use Windows Explorer to open the StartMenu or its AllPrograms child folder like any other folder, and then you can copy and paste icons into it.
I didn't say anything about clicking a shortcut. I said to create a shortcut that points to the desired folder and then open the Start menu AS A FOLDER so that you can copy/paste icons. This is "THE CORRECT ANSWER TO THIS QUESTION." These are extremely straightforward steps to follow.
THAT MUCH should have been painfully obvious. I can't teach you how to open a folder.
Par for the course. A great many computer complainants are "unhappy" with their answers. Remarkably, those who ask sophisticated questions are always happy with the response. Those who ask "How do I log in?" find every expert respondent to be an imbecile.
Had to do with a setting, eh? Your first remark: I want to "in a folder's shortcut to my task bar and/or start menu." THAT HAS NOTHING TO DO WITH "A SETTING THAT NEEDED TO BE CHANGED."
I don't mean to harass you. However, if no other expert is willing to contact you, that should tell you something. Many experts decline to get involved when they perceive that interaction with the client will likely offer diminishing returns.
Thank you so kindly for trying to help me. I sincerely ***** ***** I am required to post this response so that the system doesn't keep bothering me with "Customer awaiting reply." Please do not respond. Thank you.
