It is possible to use the same account to log in at several workspaces at the same time, but with this use, where the logged in with the same users, negative effects may occur. Here is some of them:

• you cannot run some programs at the same time, for example, browsers Chrome, Mozilla.
• you cannot have different account settings, and changes to settings on one will affect both workplaces.
• due to the use of a shared cache, there is a possibility of data loss when saving documents.

In this connection, it is recommended to create a separate account for each workplace.
To do this, click Start / Control Panel / Accounts and Family Safety / User Accounts / Add or Remove Accounts / Create Account, then enter a name for the new user account, select its type and click Create Account. You can also add an account directly from JoinCloud – see. Setup an automatic user logon

You can completely prohibit the simultaneous entrance to workplaces under one user, for this you need to apply a special setting.
