If our system cannot cope with the .ATT extension and failed all the automatic and semi-automatic methods of teaching it this art, manual editing of the Windows registry remains. This registry stores all the information related to the operation of our operating system, including the connection of file extensions with programs for their maintenance. Team REGEDIT inscribed in the window „search for programs and files” or "run in the case of older versions of the operating system, gives us access to the registry of our operating system. All operations carried out in the registry (even not very complex ones regarding the .ATT file extension) have a significant impact on the operation of our system, therefore, before making any modifications, you should make sure that you have made a copy of the current registry. The section we are interested in is the key HKEY_CLASSES_ROOT. The following instructions show, step by step, how to modify the registry, specifically the registry entry containing information about the .ATT file.

Step by step

  • Press the “start” button
  • In the "find programs and files" window (in older versions of Windows it is the "Run" window) enter the "regedit" command and then confirm the operation with the "ENTER" key. This operation will launch the system registry editor. This tool will allow not only to view existing records, but also to modify, add or delete them manually. Due to the fact that the registry of the Windows system is key to its operation, all operations carried out on it should be performed judiciously and consciously. Careless removal or modification of an inappropriate key can permanently damage the operating system.
  • Using the ctr+F key combination or the Edit menu and the "Find" option, find the .ATT extension you are interested in by typing it in the search engine window. Confirm by pressing OK or using the ENTER key.
  • Backup copy. It is extremely important to back up the registry before making any changes to it. Each change has an impact on the operation of our computer. In extreme cases, an erroneous modification of the registry can make the system unable to restart.
  • The value you are interested in regarding the extension can be manually edited by changing the keys assigned to the found extension.ATT. In this place, you can also create the necessary entry with the a.ATT extension yourself if this is not in the registry. All available options are in the submenu (right mouse button) or in the "Edit" menu after placing the cursor in the appropriate place on the screen.
  • After you finish editing the entry for the .ATT extension, close the system registry. The introduced changes will come into effect after restarting the operating system.
