Workaround for metro apps not launching and enabling side-by-side apps

Minimum resolution for fully working Metro UI is 1024x768. But most current touch devices out there have resolution of 1024x600 or smaller, which means that we could not enjoy testing new metro UI.

Fortunately, Intel added a feature into their drivers that allows you to get bigger resolution on same screen. Of course enabling that means odd looking screen (due to aspect ratio differences) and slightly reduced performance. But I guess It's OK for testing until we get something better. This works only for Intel graphics, so ION or any other non-intel graphics users, you are out of luck. Let's start:

1. Install latest drivers for your graphics. Windows 8 may already have latest drivers installed, but it's better to play safe and install latest drivers. Of course pick Windows 7 ones, since there are no drivers specifically for Windows 8 available yet.

2. Swipe left from right side of the screen to get little menu. Select "Search".

3. In search menu select "Apps" and type "regedit" (without quotes) into search box.

4. On left side you should get one result with text "regedit". Tap on it. If you get any UAC dialogs, accept it.

5. Registry Editor will open. Go to Edit --> Find and enter "Display1_DownScalingSupported" into search box. Make sure that all 3 checkboxes are checked (Keys, Values and Data). Start search.

6. After some seconds of searching, it should find an entry. On the right pane, you should see Display1_DownScalingSupported entry. Double tap on it, enter 1 under "Value data" and press OK.

If you are using Consumer Preview, skip points 7-9. It does not work anymore.

7. On the left pane scroll to the top and then find HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\AppPositioner (tap on arrow next to HKEY_CURRENT_USER, then on arrow next to Software etc.)

8. If you see "AlwaysEnableLSSnapping" on the right side, double click on it. Otherwise right click on the pane (hold your finger until you see square appear around it) and select New --> DWORD Value. Name the new value "AlwaysEnableLSSnapping" (without quotes) and double click on it.

9. Like in step 6, enter 1 under "Value data:" and confirm.

10. Reboot your computer.

11. Go into display options. You should now see new resolution options. Select any resolution that is 1024x768 or higher and you should get fully working metro UI :)

I did have the same problem and found out the RMClock program was the cause, I used the program for undervolting, while I was using it I couldn't play Piano, you could try disabling programs one by one and find out which program conflicts with Piano and let us know.

Nice!
I hadn't tried the Piano App recently because, when I first installed Win8 8102 DP back in September, it didn't work.
I have, in the interim, acquired a Live ID but didn't bother to check out the Piano App again ... until reading your post.

It does, indeed, now work. :)

First try installing your graphics driver im in acer notebook so you might wanna look it in your notebook manufacturer website and find a graphic driver install it...then try searching in the registry again

Seems broken in release preview, my screen remains black, tried it a bunch of times on x86 and x86-64, inputs work, machine has clearly booted etc, but from the boot logo on the screen remains pitch black.

Anyone managed to get it to work on RP? It's a bad solution anyway imo, makes the screen look odd, I wish there was a more clear-cut way to just force metro apps to work, instead of making the screen the wrong resolution.

I stopped using that, because I don't use metro apps anyway (they are very inferior to desktop alternatives).
Agreed, except on a tablet, which is what I have.
