If our system cannot cope with the .ICS extension and failed all automatic and semi-automatic methods of teaching it this art, manual editing of the Windows registry remains. This registry stores all information relating to the work of our operating system, including connecting 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 .ICS file extension) have a significant impact on the operation of our system, therefore, before making any modifications, you should make sure that a copy of the current registry is made. 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 .ICS file.
Step by step
- Press the “start” button
- In the "find programs and files" window (in older versions Windows systems this window is "Run"), enter the command "regedit" 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 .ICS 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 .ICS extension. In this place, you can also create the necessary entry with the a.ICS 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 .ICS extension, close the system registry. The introduced changes will come into effect after restarting the operating system.

- ICS file infection (viruses)
- too small computer resource
- outdated drivers
- removal of the ICS extension from the registry of the Windows system
- incomplete installation of a program that supports the ICS extension
Fixing these problems should lead to free opening and working with ICS files. In case the computer still has file problems, you need to take the help of an expert who will determine the exact cause.

In the "View" tab there is an option "Hide extensions of known file types" - you must select this option and confirm the operation by pressing the "OK" button. At this point, all file extensions, including ICS, should appear sorted by file name.
