The EXE file extension stands for Self-Extracting or Executable files. This is a very common extension, and appears on files which users generally call programs. Double clicking on an EXE file should result in the program launching itself. EXE files can be as simple as INSTALL.EXE, a familiar short program packaged with most Windows software which places the software on your computer and prepares it for use. However, even large and complex software applications will have the EXE extension. This enables a person to tell at a glance which file in a list is an actual program.

Regtask was able to clean up my computer and speed up the performance! I highly recommend it
Jo H.
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.

EXE files have been in use since DOS (Disk Operating System) was the standard operating system. They are the standard in the Windows platform. Older versions of Mac OS need emulation software to run them, but OS/2 should not require any additions. Some old computers may have EXE files which do not open programs but may be self-extracting archives or other files. These will not be found on newer computers.

More Info Regarding File Extension Exe
Because these files are more basic than those created by an end-user software package they are not opened by software, but by operating systems. Microsoft Windows operating system will run EXE files. On the Mac platform, Parallels Desktop with Windows installed must be used with the OS, but OS/2 should run EXE files. For Linux, Wine and Cedega operating systems will open EXE files. Wine and WineX (which became Cadega) were developed specifically to run Windows based games on Linux systems.
With older versions of operating systems there were many custom EXE formats
If an EXE file will not open there may be registry errors. Liutilities.com or fileinfo.net offer a free registry scan and booster to fix errors. This is certified safe by Microsoft. If shortcuts suddenly begin developing LNK extensions instead of working properly, registry problems are the likely culprit.
Viruses can attack registry files. If the error message says “Windows cannot open this file. It needs to know what program created it,” or “Windows cannot find xxx.EXE,” then the registry has probably been damaged. Depending on your version of Windows you should be able to download a program to restore the default associations for the registry. Only people who know what they are doing should alter the registry file in an attempt to fix the problems. Filext.com offers advice for those who believe they are competent to work on the problems themselves. This site offers detailed instructions for problems with Windows 98 through Windows Vista. Never work on the registry file without creating a backup copy of the original.
Other likely problems are either corruption of the program file itself, or attempting to open programs with incompatible operating systems.
Corruption of an EXE file usually can only be fixed by reinstalling the software. This often results in the loss of custom settings which may have been created by the user, and is annoying, but solves the problem. Some software programs save user settings in a separate module which is not overwritten by a new installation.
Older 16-bit EXE files are unlikely to run on newer operating systems. When the files are examined in ASCII these begin with the letters MZ. 16-bit New Executable files begin with NE in ASCII. On OS/2, 16/32-bit Linear Executable can be identified an LE label in ASCII.
With the introduction of Windows XP, the DOS operating system was abandoned. Windows XP is more friendly to older software than most Windows upgrades, thus recognizing and running many more existing EXE files (programs) than most computer upgrades. Transitioning to Windows Vista does not give such pleasant results. Usually the only solution is to either buy an upgrade of preferred software, or if this is not possible abandon software and files that work perfectly well. Many people choose to keep an older computer available to use programs and manipulate files which will not run on Vista. Migrating such files to some acceptable software that will run with Vista is recommended or the data will eventually be permanently lost.
