I want to add a new item (in this particular case a shortcut to Putty SSH client) to my Windows 10's All Apps section.
I have already found out that I can "Pin to Start" any item, however, this will only create a new tile on the right side of the Start Menu and won't add any new item to All Apps. Thus, pressing Win and typing "putty" won't return any result.
Creating a new shortcut and adding it to shell:start menu has the same effect as pinning to Start, so it's not a solution.
Note: this question might look the same, but the accepted answer doesn't apply to my requirements as I need the item to be searchable, and not only a new tile.
Note 2: I can confirm that after waiting several hours for Windows to reindex its index I manually rebuilt the whole index, but putty still can't be found neither in search results nor in "All Apps" list.
