Many users may find that they come across a "protocol unknown" problem when trying to run certain types of hardware or software. It is a common problem and almost every user will encounter it at least once in their life. For them to solve this problem, it is important for them to understand what the word "protocol" means to a computer and what, exactly, is left unknown.

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.

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.

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.

To a computer, a "protocol" is a means of "talking" with a piece of software, a network, a device, or another computer. It is a series of standardized commands and controls which allow the computer to exchange information with the object in question. To explain what this means, it is helpful to think of a protocol as similar to a language, such as English. Two people who have never met before can exchange information if they can both speak English, but not if one speaks only English and the other speaks only Japanese. In either case, both persons are able to speak, but they can't identify the other's meaning. A "protocol unknown" error is simply a computer's way of saying that it doesn't speak the language of the device in question.

More Info Regarding Protocolunknown
The world of computing is thick with protocols, which tell computers how to speak to one another. Almost all operating systems come with a large suite of protocols, although the more recent the operating system the more protocols it will have. Additionally, keeping operating systems and web browsers up to date will allow the computer to have more and better protocols, to facilitate communication. This means that "Protocol Unknown" errors are more common on older machines than newer ones.
The most common occurrence of the "Protocol Unknown" error is when surfing the internet. The reasoning behind this is obvious, as the internet is basically when a bunch of computers talk to one another via standard means of telecommunication such as phone lines and satellites. Because there are so many computers on the internet, with so many different sorts of software on them, it's only natural that computers will often find themselves not speaking the same language.
In order to prevent internet-based "Protocol Unknown" errors, it is necessary to keep one's web browser fully updated. This includes add-ins such as JavaScript and Adobe Flash, which are necessary to access some functionality of some machines. Keeping a computer's operating system and drivers is also important in this regard. The computer can't communicate with the outside world if it's modem or LAN port isn't properly updated with all the latest protocols. These won't prevent all "Protocol Unknown" errors, though, since many of them are the result of webmasters or hosting services who aren't keeping their own software and systems fully updated.
The "Protocol Unknown" error isn't just limited to the internet, though. Files which have lost their extension may trigger a "Protocol Unknown" error, especially when relating to hardware. In general, files without an extension were most likely written on an operating system that does not require file extensions (such as Linux or MacOS) and they may not be compatible or readable on a machine which uses Windows. It may be necessary to reinstall software in order to fix this problem, or to download an alternate version which was programmed for Windows.
Missing file extensions can also occur when a file has been renamed improperly (a common error in Windows). This sort of problem most easily arises when Windows has been set to display the full name, including the file extension, of every file on the computer. A user who carelessly renames the file without adding the appropriate ending will create a file that the computer can no longer recognize, even if the computer just opened it under another name a short while ago. Luckily, this can easily be solved by simply renaming the file with the appropriate extension, or opening it in the program it was created and saving it as the appropriate sort of file. Users who are very novice and have trouble determining what sort of file extension the file is supposed to have are advised to try opening it with MSPaint, WordPad and Internet Explorer. The vast majority of files on any computer are either pictures, written documents, or objects opened by a web browser. The file's appropriate extension can then be determined and added to the file name.
