I need major help right now. Something happened to my computer, and now Windows Explorer won't work. I managed to get Firefox open, but I can't do much else. I need serious help. When I try opening something, it'll show a window with stuff like this in it: It's saying "Data Execution Prevention - Microsoft Windows": To help protect your computer, Windows has closed this program. {image of the command prompt thing" Name: Windows Command Processor; Publisher: Microsoft Corporation. [Close Message]

I don't know what to do and I need very major help fixing this. I can't open anything at all, it's amazing I was able to get firefox open. I've tried restarting the computer about 4~5 times...

Hi hakumeikage09,

Did you install any new software or make any changes to your computer before this started? Any updates or upgrades? Which operating system are you using?

I only downloaded a program for my phone, nothing more. As for the OS, I'm using XP. And it seems to have fixed itself, ubt I dont know how it did it and I'm afraid it might happen again.

Here's some information that might help if it comes up again:

First this article which relates specifically to DEV (Data Execuation Prevention) with a workaround:

http://support.microsoft.com/kb/875351


And second, remember that System Restore is there to help you switch your registry back a notch when you need to, so you can see if something you just changed on the computer is the cause of the problem.

If the problem is fairly recent (within the last week or so) I recommend doing to following:

If you have System Restore turned on (it's turned on by default), then go back to a system restore point which precedes the installation of the phone software you put onto the computer. To do this, go to Start / All Programs / Accessories / System Tools / System Restore. Select Return my computer to an earlier restore point and click on next. Click on a highlighted date from just prior to the installation of the phone software and follow the prompts. Your computer will reboot. After it reboots, see if the problem you're having still exists.

If this does not resolve the problem, go through the same steps as above with system restore, only this time select the option to reverse system restore to what it was previously.

If the above helps, then check your DEV settings before attempting to reinstall the phone software. To do this:

1. Right click My Computer and select Properties
2. In the new window select the Advanced tab
3. In the Performance section click Settings
4. Select the Data Execution Prevention tab.
5. Be sure that the following is selected: Turn on DEP for essential windows programs and services only.
6. Click OK. You may need to restart afterwards.


Let me know if any of this helps.
