One of the most challenging things that the average computer user may have to face is dealing with different file types, especially if the user lacks an understanding of the file types' purpose and how to properly handle them. This issue comes up commonly when the user has to dig deep within the inner workings of an operating system or a software program for any number of reasons. Users may also wonder about strange file types they may come across while installing a new program, removing an old or unused program, or simply by cleaning up old, unwanted files on a hard drive. Anti-virus software will sometimes alert users to infected files, only for those users to wonder and panic over whether it is safe to remove that particular file. Most times, all these users want to find out is whether or not these files are safe to remove and if removing them will have any adverse effect on either their software programs or their operating system. All it takes is some simple research to find out the purpose of these file extensions and the reason they are there in the first place.

My computer was always popping up with registry errors and I couldnt get rid of them. Regtask did the job for me and took less then 5 minutes to speed up my computer.
Samantha J.
I have to admit I'm no computer geek. When something goes wrong, I usually have to call someone to fix it and it costs me a lot of money. When my computer started to experience random freezes, I just used Regtask and now it works normally again.
David G.
My computer is 5 years old and runs extremely slow now. I was a bit sceptical about using Regtask, but just decided to give it a shot in the end and it worked out fantastically for me.

The m4a format is one that most people will not necessarily pay attention to unless they are avid audio / visual fans or producers of audio / visual content within the entertainment industry. The m4a file extension belongs to the MPEG-4 family of audio and video coding formats. In essence, the m4a file extension is a “container” of sorts for compressed high-quality audio and video data, similar to the highly popular mp3 audio file format. Unlike the mp3 file format, the m4a format is capable of playing higher quality audio and video due to the mechanisms involved in its coding and compression.

More Info Regarding File Extension M4a
The m4a file extension is an offshoot of the mp4 file format also found within the MPEG-4 family of file formats. Both formats are nearly identical in essence, as there is no fundamental difference other than the file extension names, and both were created by the ISO/IEC Moving Picture Experts Group (otherwise abbreviated as MPEG). Overall, the MPEG-4 standard was created as a solution in how to effectively compress audio and video data in a usable, high quality digital format. The MPEG-4 standard comes in 23 “parts”, each part representing different functions and goals within the MPEG-4 standard. The mp4 and m4a file extensions fall under Part 14, internally known as ISO/IEC 14496-14.
The presence of both mp4 and m4a file formats may be confusing to the average computer user, since it seems that both formats largely serve the same purpose. The status of the mp4 file extension as a container format means that within said format, there may be any number of audio and video streams, making it very difficult to determine the type of stream or content solely based on the file extension name alone. Apple Inc., whose QuickTime container format serves as the foundation for the mp4 file format, opted to popularize the m4a format, often using it for audio-only content as well as audio book and podcast content. Because of this, the m4a format is widely used by Apple's iPod portable music player, plus Apple's iTunes music download store. The format is also used by Microsoft Corporation's Xbox 360 video gaming system and the Zune portable music player.
Software programs that are able to play the m4a file format include QuickTime Player, RealPlayer, VLC media player, Winamp and foobar 2000. Generally, if a software music player is able to play mp4 files, then it is also capable of playing m4a content. Users of audio / video editing programs who create MPEG-4 content are also able to choose whether or not they want their content to bear either the mp4 file extension or the m4a file extension. It is also possible to convert the mp4/m4a file content into the more popular mp3 file format, using specialized conversion programs.
