Windows 8 with 2 Microsoft accounts?

You could create a secondary account that is Microsoft account and leave the current one as it is. And it should only sync the Microsoft acc. eneabled user and you can still have your old things as they always were, in case you question MS security and what they might collect about you.

 

App store and Microsoft account

Thank you for the advice

I see what you mean about the password but i think its a backward step to compromise my Microsoft password to to use the app store

 

Windows 8 with 2 Microsoft accounts?

Yea, I would create a local account and just use your school account to login to Outlook and Onedrive.

Edit:
Here switch between local and microsoft account.
