My computer nags all the time on me signing in using Microsoft Account. I've chosen not to do that but e.g. Skype (the modern app) requests that before it starts up. I want to keep using my local, old school login procedure and I want to use my pre-existing Skype account.
What will happen if I tell my computer that it can log in using Microsoft Account? Will the old login procedure still work or will it be expunged and substituted for only Microsoft Account?
Please note that I'm running Win 10 opn a Surface 3 (if it's of any significance).
