How to simulate no browser installed under Windows

In a python program running under windows I used the os.startfile() function to open something.html file.
I now wanted to test the edge case of having no browser installed.
How do I simulate this case under Windows without uninstalling all browsers?
I already tried to remove the default programs connection to html files but windows doesn't like that and doesn't let me do it.

Error adding modes in Processing

I recently downloaded Processing 2.2.1 and when I tried to add a programming mode through the menu on the right side, I got a java.net.SocketException: Network is unreachable even though I can obviously connect to the internet, and an error message at the bottom of the "Add Modes" popup that said could not find listof available contributions instead of a list of the modes. I know that some modes can be manually downloaded and unzipped but I have yet to find a .zip file for the Python mode. Is it possible to fix this error so that I can download the modes through the GUI box and if so, how?
I had previously downloaded it for my Linux machine which runs Ubuntu and everything worked fine there but I was trying to migrate everything to my Windows 32 bit so I just re-downloaded it today for windows and got this error.

Windows Phone Power Tool (Pre WP-8) Fails To Load Folder Content

My environment : Win7, VS2010 Pro, Windows Phone Emulator 10.1.40219.390, HTC T8788, Windows Phone Power Tool v1.6.
I need to Get multiple files (they are <3kb json files) to my dev box from a folder on my emulator/device. I had been happily doing this with Isolated Explorer command tool and/or Windows Phone Power Tool till the number of files was very limited. As soon as the number of files increased in the folder both the tools mentioned above failed to open the folder from device. The application on device and emulator is handling large number of files as expected (tested with 4000+ files). Following are my findings regarding the issue with WPPT (and IS explorer): if a folder contains more than 1024 files, WPPT does not load the folder. The physical size of individual file in the folder does not matter. The issue can be reproduced with same effect on emulator and device. On further investigation I found that WPPT breaks at a call to Microsoft.SmartDevice.Connectivity.RemoteIsolatedStorageFile.GetDirectoryListing() which just says - "Unspecified error" with no details. It seems the said API method is now obsolete and i could not find any substantial information on MSDN about it or the issue
Did somebody else also encounter this problem? Is there some way I can pull large number of files (4000+) to my dev box from IS folder on device/emulator (please note, i can only work with the environment mentioned above, so Win8 or WP8 emulator are out of question)?
Regards.

App inventor blocks editor is starting slow and return error "could not download starter application..."

I'm trying to run blocs editor for app inventor. It's starting slowly and then returns message:
We could not download the starter application from the server in order to install it on the device. This may prevent the "Connect to Device" button from working.
This error can occur if you have tried to start the blocks editor with a previously downloaded ".jnlp" file.
I have installed last version of java, other java applications are working fine. How does make the block editor work?
There could be lots of reasons. Which browser are you using? Did you already try another?
Probably there is some kind blocking software running on your machine, perhaps a firewall. There have also been reports of this from misconfigured virus scanners.
You also might want to take a look at the troubleshooting page. If this does not help, post a question in the Getting Set Up and Connecting Your Phone to App Inventor forum.

Trying to Run js on firefox - it works fine on linux but not on windows

I wrote a js using ext.
I try checking this script.
When checking is on small data I receive the same result on Firefox Windows and Firefox Linux.
But when I try it on large scale of data Firefox Linux work perfect but for Firefox Windows I get the exception -
Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY)
[nsIDOMHTMLCanvasElement.width]
I'm thinking that your getting this error because you are trying to display something using Canvas that is too big for FF. Could you post any of your code here or describe the data you are trying to check? I've also heard that this can be an OS based problem are you running Win7 64bit (most commonly sees this error) try running from a 32bit windows machine.
