inadvertently, click "always use the selected program to open this type of file" how undefault and redo icon to the icon of white empty file?

I accidentally click "always use the selected program to open this type of file" on the srt file. How to make it undefault and again the icon to icon file empty white?

You can do this via a registry change, but it is more appropriate for a typical user to simply use the system restore:

System restore

Ever wished that you can go back in time following a bad fall? With Windows, you can.

Installation sometimes a driver or a program can make Windows run slowly or erratically. System Restore can return programs and system files from your PC to a time where everything worked, potentially prevent hours of troubleshooting of headaches. This will not affect your documents, images or other data.

In Windows 7, you can create system restore points more and see exactly what files will be deleted or added when your PC is restored. For more information, see create a restore point.

For more protection, use the restore system backup and restore, which is designed to help save email, photos, documents and other personal files.

To use the system restore

Before you start the system restore, save open files and close all programs. System Restore will restart your PC.

  1. Open system restore by clicking the start . In the search box, type restore the system and then, in the list of results, click on system restore.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. Follow the steps in the wizard to select a restore point and restore your computer.

    For more information, see System Restore: frequently asked questions.

In Windows 7 system restore can prevent headaches hours after an accident.

  • A search engine click always uses the default search engine

    In the search bar, I type the word London and press enter and get the results of a search Google (default search engine).
    I click on the magnifying glass to open the search drop-down list and click the icon for Wikipedia (to perform a search on Wikipedia for the word London). However, the results are not Wikipedia but are the same as my previous research on Google. The only way I can get the research to be done on Wikipedia is to change Wikipedia to my default search engine.
    Am I misunderstand how the search with a single click is supposed to work, or you can tell me what I need to change to make it work?
    Thank you

    Using the arrow keys or tab to the search engine icon had the same result by clicking on the icon to directly search engine, any search engine was selected the search is always performed by the default search engine.

  • Cannot change the default program to open certain types of files more

    I opened the month .package file type by using a specific .exe designed to cope.  I got this morning and by clicking on a .package file brought to the top of the screen "choose default program".  I chose the appropriate program, but it does not appear in the screen of the recommended program, and I can't find any way to make it use the default .exe.   I tried to change it in the area of selection of the programs in the the control panel by default and hot at the same result.  I can still open the files by starting the program manually and choosing the option 'Open', but it is a tedious and repetitive task!  This program is used to group graphic files in a specific format, and it is not uncommon to open and close files .package 5 6 times in a period of 10 minutes.  I really need to fix this ASAP.  My productivity has come to a near standstill.

    I'm on Win7 64-bit, the program in question is a stand-alone that has always been in its own folder in the downloads library.  I tried to move to the folder program files (x 86), but that did not help.  Windows recognizes the program when I make the request to select the default program.  When I try to use it however, it is not an option.

    I was going to link to the Microsoft Developer Network instructions, but it's a pretty large amount of information for it, so, let me suggest a small program that should be able to do it for you.
