File associations corrupted - How to fix ?

March 2015

File associations are very important for the day-to-day functioning of computers. Without them it would be impossible to run any type of file, as Windows would not be able to recognize files. File associations become corrupted due to security issues if the computer has been infected by a virus. System restore is one of the options that can be used. For this to work, it has to be turned on. Another solution is to download the file associations onto another computer and then use them via a flash drive on the infected computer in order to get rid of the problem.

There are situations when the entire file association gets corrupted due to virus attacks. The user is unable to launch any files. The only real option is a system restore. If system restore has been turned off and there is not a previous point from which to restore the PC, there is no option other than to repair or format the PC.

THE USUAL METHOD, WHICH IN THIS CASE WILL NOT WORK

Running registry fixes will not work because all file associations have been corrupted.


SOLUTION

Be sure to download fixes for important file types, especially exe.lnk and reg, from the following websites:
