FYI: I work as a standard user on my system. When I install apps, I typically do it as this standard user. If required I enter the admin password. Since a few days I have changed to admin account type.

Apps in tiles or tiles missing, e.g.:

Notepad++ : The link points to C:\ProgramData\Microsoft\Windows\Start Menu\Programs (the tile is also misssing and was named "Anwendungen" meaning apps)

Microsoft Office startmenu tiles folder: most apps link to C:\ProgramData\Microsoft\Windows\Start Menu\Programs (some seem to be special links) (the tile is also misssing and was named "Microsoft Office")

Irfanview 64 v4.6: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\IrfanView (the tile is also misssing and was named "Anwendungen" meaning apps)

winver: C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs (the tile is also misssing and was named "Windows")

All tiles which are in Start11 (v1.47) are complete, with one exception, where it seems to be a special link.

While testing it appears to be that pin to Start11 does not pin. Pin to Start works.
