Where can I get a list of all installed Programms and start them?

Just something like a "Programm" List.

I can't even start excel on the up to date start menue - because it is't listed till after 15min of a running pc.

Other programs that are correctly installed are nowhere to be found and need to be started completely manual.

So where or how can I turn off this new "features" and get the old program list? without any widgets and ribbons.

Thanks for information,

Best regards Martin
