What's the big deal? I'v been able to do this on my Nexus 5 android phone for ages cross platform too. The only thing I can see it's good for really is to check the kids browsing history without having to get my hands on their computer and see if they are doing their homework or to turn their music down if it's too loud. It's possible to use dictation and see the text pop up on the computer screen, interesting when you think I don't have dictation on my mac. What I can do is record my nexus 5 screen whilst streaming video (like TV) for up-to an hour. I can't do that on my mac, that's impressive. Even ios can't do that on a single cheap device.

If you're a Windows Phone user, and live in the Microsoft ecosystem, this is a big deal as it's a feature that has been sorely missing from the platform.

Pinch-to-zoom is supported, although its kind of strange. If I try to pinch-zoom in a browser I opened BEFORE remoting in, no multi-touch support. However, if i open a new window (Chrome for instance) I get pinch-zoom, two finger scrolling, etc. So it is supported, just buggy for the time being. As far as other remote apps available on other platforms, this one has a much "cleaner" and simpler feel to it rather that tons of menus and a keyboard with unintuitive features.

Great article it is very helpful info for me to work via my Lumia 920

Just try software like logmein or Ammyy Admin.

I'm following all the steps but when I try to initiate remote connections, I get this message:
"Connection error We couldn't connect to the remove PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled.
Inquiring minds may find this error code helpful: 0x204"
Anyone knows what could be wrong?

Hi everybody. I have the same error like Lee Seng Kiat. I use a Lumia 620 with Lumia Cyan. ¿What is the problem with this?

Is it possible to know whether someone(me) is remotely accesing the PC when my kids are using. I dont want my kids to find out. please help me and sorry for my English.. Thank you

By default remote access is not enabled in the system either. If you are still having issues "Remote Desktop credentials did not work" Try this, and it will fix this issue.
1. On your local machine Open Windows command prompt type: gpedit.msc -> Press Enter -> a new window will popout
2. Go to Local Computer Policy –> Computer Configuration –> Administrative Templates –> System –> Credentials Delegation Double Click on “Allow Delegating Saved Credentials with NTLM-only Server Authentication” By default it will be “not configured” You will see radio buttons -> Enable the policy Click the “Show” button in the options window below and enter the value “TERMSRV/*” (without quotes) into the list. Click Apply button
3. Do the same thing for the following policies: Allow Delegating Saved Credentials Allow Delegating Default Credentials with NTLM-only Server Authentication Allow Delegating Default Credentials
4. Make sure that "Deny Delegating Saved Credentials" is not enabled or does not contain “TERMSRV/*” in the list
5. Close all windows
6. Open a command prompt and use “gpupdate /force” command to apply the policy directly
7. Now try to remote access your PC from the device.
