Has not been a while at all since Windows 10 surprized everybody with bugs all over again... I was pissed off fr two days of looking for an answer why some programs do not want to start automatically when droped off on Startup folder (for current user or for All users, doesn't matter). Lot of stupid answers from people from microsoft that recommend to do a sfc scan. Luckily, most of us are not so stupid to screw up other things trying to fix simple ones.
So the solution is by changing the EnableLUA to 0:
Run > Regedit:
Set the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ System \ EnableLUA to 0
Most of us using UAC to never notify previously in the upgraded windows version but in my case was a clean install as after some updates period promrams on startup ceased to work.
