When Microsoft released the Windows 8.1 Preview, they made it pretty clear that you would have to sign in with a Microsoft Account. In the FAQ under “What are the system requirements for Windows 8.1 Preview?” they stated the following: “In order to use Windows 8.1 Preview you must sign in to your PC with a Microsoft account. The option to create a local account will be made available at the final release of Windows 8.1.” That same information has been echoed over quite a few sites.
As it turns out, you can create a local account on the Windows 8.1 Preview.
When you get to the screen that prompts you to log in with your Microsoft account, type in any email address and random characters for the password then click Next.
Click “create a local account now.”
On the Your account screen, the error will show, “Somethings went wrong and we couldn’t set up your Microsoft account. For now you can create a local account. We’ll help you set up your Microsoft account later.”
Click “Create a local account.”
Type in your desired User name, password, and password hint. Click Finish.
