Installed Windows 8 Pro, completed the requirements for the 'Trust this PC' link in Action Center. Had several 'trusted' PCs with the same name (from previous installs) and removed them from the list. Thought the PC listed at the top of the list was my current PC, it was not. Now, when trying to click 'Trust this PC' in Action Center am just sent to the Live account page and no unique code is sent to my phone, leaving me unable to trust my current PC/Windows install.

One of the great benefits of running Windows 8 on multiple PC’s you own, you can easily sync common settings across computers such as passwords for apps, websites, networks in addition to other benefits such as themes, backgrounds and color schemes. To do this, you need to trust your Windows PC.

Start by launching Change PC Settngs (Windows + I)

Under PC settings, click Users tab

On the right hand side of the screen click Trust this PC

Sign into your Microsoft account which can be either a Windows Live ID, Hotmail, MSN or Outlook.com

Click Next to Confirm your computer as a trusted PC or you can visit a existing trusted PC and do the confirmation there from http://accounts.live.com/p.

The PC’s you sign in with your Microsoft Account from now on will be a lot more seamless.
