The default pdf handler in Windows 8 is the "Reader" app, which runs in the new UI only. Aside from using a "normal" pdf reader (Foxit/Adobe) is there any other way I can make the Reader app run in desktop ui mode. enter image description here

I am looking for this, because I am used to opening PDF and an editor side by side (50%). The modern UI only gives me one-thirds, which is not what I want

Not possible because the Reader app was only made to be run Windows 8. (Basically what I mean is that you can only run the Reader app from the Start page)

You can "snap" the Windows Reader to the Desktop.

  1. Open Windows Reader
  2. Go to Desktop
  3. Point with the mouse to the top-left corner until a box with Windows Reader icon appears
  4. Right click on it, and select Snap left or Snap Right

The PDF reader is a Modern UI app; you cannot run Modern UI apps on the desktop.

You could run it on a virtual machine instead.

wait. Run a whole OS just to read PDFs? – Journeyman Geek Oct 28 '12 at 9:55

Just use the Control Panel - Default programs and change the file association for .pdf to acrobat reader or foxit or whatever reader you prefer.

PDF's will then open up in windowed mode.

Not UI mode but it is more manageable with :

Windows key and left, right arrow will make it 50% of the screen.
Process to use the windows key and D to put the desktop on the other side.

You also have got a bar you can move to set the size for yourself then
