The window can't be resized as far as I know. I went back and checked all the commandline options and searched TB's FAQ, and forums.
i dont believe there is a way either. 800x600 is really low and lot of 32 bit apps in WinPE now run at 1024 x 768. If you don't want to make your overall environment higher, you could add in a script with an application like SetRes that will change the resolution when imagew runs and change it back when its done.
Here's an easy way to change the resolution in your Windows PE boot Disk.
Just add this line to your Startnet.cmd (i put mine right after the standard winpeinit.exe line)
Of course you also have to create the file called PEOptions.xml (or any name XML) and include this text:
<?xml version="1.0" encoding="utf-8"?>
<component name="Microsoft-Windows-Setup" processorArchitecture="x86"
publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS"
You can probably include less of the text in this example, but I copied this from somewhere a while back and never experimented with tweaking it because it worked.
Thanks Jeremy G. This worked like a champ! I did remove the two line items for EnableNetwork and EnableFirewall though as they are handled elsewhere in the PE setup. The Imagew 2 window shows up nice and clean in the middle now. Beauty.
For anyone else who might follow this, I edited the Startnet.cmd file that is in the WinPE Boot.wim image and added the PEoptions.xml to the same folder within the image (Windows\system32). I mention this because there is also a Startnet.cmd file under \\corename\ldmain\landesk\vboot. I did not edit this file and am not sure when this one would be used over the one in the Boot.wim file.
Please enter an enhancement request for us to have this file there by default.
