  Hello

  You did changes to the computer before this problem?

  Step 1: Check if the problem persists in the clean boot state.

  From your computer by using a minimal set of drivers and startup programs so that you can determine if a background program is interfering with your game or program. This type of boot is known as a "clean boot".

  Reference:

  When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

  1. click on start and then click Run.
  2. type msconfig and click OK.

  The System Configuration Utility dialog box appears.

  3. click on the tab general, click Normal Startup - load all services and device drivers and then click OK.
  4. When prompted, click on restart to restart the computer.

  Step 2: Also, look for error messages in the event viewer. If you find error messages after return the exact error message so that we can help you better.

• How to change a default program to open the file instead of Widnows Media Player

  Original title: Media Player

  Windows Media Player opens many of my files (which in fact cannot be opened).  What can I do to make the Media Player ceases to be the default to open my files?  I can't even open Internet Explorer because Media Player wants to open.

  Hello

  By the description, I understand that Windows Media Player is been activated as default program to open all the files.

  You can change (set another program as default) your default program following the steps mentioned below:

  1. open default programs by clicking the Start button, click default programs.
  2. click on associate a type of file or Protocol with a program.
  3. click on the file type or protocol that you want the program to act as the default value.
  4. click on the change agenda.
  5. click on the program that you want to use by default for the selected file type, or click the arrow next to other programs to show other programs. (If you don't see other programs or your program is not listed, click Browse to find the program you want to use, and then click Open. If no other programs are installed that are able to open the type of file or Protocol, your choice will be limited.)

• Cannot change the default program for opening .dll

  For some reason any, since I first linked the default program to open files .dll with Visual C++ 2010 Express (which is not truly attempt open, but instead of it gave me a message somewhere near the lines of "File not supported - Type does not open", incidentally) by chance I could not change since. I took a screenshot of the dialog box to try to change (URL below after all), but I noticed that the box was grayed out (the theme I have is a modified version of the classic Windows theme, but on 7, to clarify the operating system). I also tried to select a file after having hit the "Browse" button, but it didn't open anything. I tried several programs in the present to open, much less to change the default value (these are two notable examples): Netbeans - primarily an IDE for Java, but can open binary files even if she's not actually modify them (note: I changed absolutely nothing on any of them even if I has modified it to make it the default program but this problem affects more than just the ones) (, and it did not start until the last default) and Notepad. I went through the 'Open with' dialog box, and this is where I first encountered the problem of it (described above) outside the Control Panel, which it wouldn't let me change the association of file of it in particular, even if I didn't have one of these questions with any other type of file I tried to change, before or after this madness.
