Question #3 - I'm constantly receiving file extension errors, such as the .mui file extension error - how can I resolve the issue?

Typically, file extension errors occur due to the following two reasons:

• Incorrect file association
• Corrupt files

Both of these causes and their remedies are discussed in detail below:

Incorrect file association - The most common cause of incorrect file association is a corrupt or damaged registry. As your registry grows old, it not only gets filled with a lot of unwanted information, but also becomes fragmented. Deterioration in your registry's health leads to incorrect file associations which in turn cause various file extension errors.

To fix the matter permanently, you need to sweep clean unwanted registry entries and defrag registry files. The registry's structure is very complex and you will be well-advised not to tamper with its contents on your own. Instead, we recommend you seek the services of a reliable registry maintenance tool. Such tools are easy to use and with just a few mouse clicks you can clean, as well as defrag your registry.

Corrupt files - The most common cause of corrupt files is malware infection. Malware programs alter the contents of your files, making them corrupt. As a result of this behavior, file errors occur whenever an attempt is made to access or use the infected file. To resolve the issue, first update your security program with the latest malware updates and then perform a complete malware scan on your computer.
