Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

Switch laptop sign in from MS account to Local Account questions

Hi, Ive just switched from signing in to my laptop with a Microsoft Account to signing in with a Local Account instead. My laptop was always listed as a Device on the opening screen along with a map showing its location when I looked in my Microsoft Account. Under Devices I could also view my laptop along with other bits of various information about the device and its location was always shown on a map there too. After signing into my laptop with my Local Account ..If I sign in separately to my Microsoft Account afterwards Ive just noticed that having switched to a Local Account my laptop isnt shown on the opening Microsoft Account screen anymore and its not listed in devices either. Is this normal behaviour? I was expecting to still find my laptop listed in Devices. Also...Under Update and Security/Activation..it used to say Digital Licence linked to a Microsoft Account. Now it just says Windows is Activated with a digital licence. Is all this normal behaviour if you sign into a laptop with a Local Account instead of a Microsoft Account?

 

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?
