I have been experimenting with Cubase, working my way through the various settings,
but I seem to have made a mess of things, is there any way to perform a “Factory Reset”
Other than re-install the software.
I had experimented with chords, notation, audio etc etc… and need to undo every thing and start over.
thanks.
Reinstalling Cubase alone does not, in fact, reset it to factory settings.
This would be the perfect time to learn the essential troubleshooting step for Cubase, running Cubase in safe-start mode. That might be all you need to do. After that’s done it makes sense to reinstall if you still think you need to.
Hold ctrl-alt-shift while Cubase launches.

Welcome!
Holding ctrl-alt-shift doesn’t bring me to safe mode in Cubase 10. Instead, it goes to ‘Cubase Open Document Options’. Is there another way to launch safe mode?
You are pressing those keys once the Cubase start screen appears and not before… right?
Also… suggest you list your computer OS specs in your forum signature.
Regards. 
If you are exploring different settings and changing them enough that you loose track of what you’ve done, then you might want to save different variants as descriptively named presets - including the initial settings. That way you can easily get back to a known state.
That is right, I am not pressing those keys before the start screen appears. I have just listed the specs in my signature… good point. 
I just tried it and you are right… if you press those buttons while the Cubase start screen appears you get an “Open Documents Options” screen. I haven’t used safe start in some time now but, that is weird and I wonder if the procedure instructions to activate safe start should be revised.
However, I did get it to work by pressing the keys just before the Cubase start screen appears. So try that.
Regards
I think the instructions should be revised indeed, because pressing those keys before the start screen appears worked! Thank you. 
Hmm, I actually successfully reset Cubase 10 a few weeks ago, but now when I try it I’m getting the same “Open Documents” dialog box.
Tried it just after double-clicking on the Cubase Icon, then on the first screen before the Hub, and even on the Hub screen. No joy.
Update:
I did a computer reboot, ran CCleaner (removes trackers and cookies, and fixes any registry issues).
Tried the Ctrl+Alt+Shift just as the first screen appeared and, NOW it worked.
Not sure if rebooting and CCleaner made the difference or what.
I’m a new user who has also screwed up the Studio settings, so my Fantom 7 won’t connect. I’d like to start from scratch. I should have gone step-by-step through the start-up manual. I contacted support, they gave me some suggestions, but nothing has changed.
I uninstalled and reinstalled Cubase, but Studio setup and my two miserable test projects were still there.
I tried Ctrl-Alt-Shift, both before and after the Cubase splash screen shows up, but this did not seem to have any effect.
Windows 10, Cubase LE 11.
Any ideas?
I tried doing what you did and still getting the open document dialog… very frustrating and inhibiting.
Hi,
You can also reset the preferences manually, by deleting (and backing before, if you want to) the preference folder.
Cubase Preferences folders are:
Mac: ~/Library/Preferences/Cubase X
Win: %appData% Steinberg/Cubase X_64
By the next Cubase start, Cubase would migrate the older Cubase preferences (from 2 major versions back), if you have any available. Btw, Cubase does this even, if you reset the preferences from the Safe Start Mode. So if you really want to get the Factory settings, delete (or ZIP, to backup them and then delete) all your Cubase preferences folder.
