exe file edit lock
1. EXE File executable program that can be used for floating positioning in the operating system storage space. Under MS-DOS and Ms-windows, this type of file extension is exe. binary executable files in 2.WINDOWS operating system, two kinds of executable files are named after the suffix · COM another is that · EXE. COM is generally used for DOS, in the Windows system execution files are generally · EXE file in MS-DOS to identify the file name extension of the executable file. The user presses the ENTER key after entering the file name without the. exe extension in the prompt line to run the executable EXE file that contains a file header and a relocatable program image. The file header contains information that MS-DOS uses to load the program, such as the size of the program and the initial value of the register. The file header also points to a relocation table that contains a list of pointers to the address of the relocatable segment in the program image. The file header form corresponds to the Exeheader structure: Exeheader strucexsignature DW 4d5ah;. EXE flag exexrabytes DW? The number of bytes in the last (partial) page expages DW?; The total and partial number of pages in the file Exrelocitems DW?; reposition the pointer in the table exheadersize DW?; file header size in bytes EXM Inalloc DW?; min. allocation size Exmaxalloc DW?; maximum allocation size EXINITSS DW?; Initial SS value EXINITSP DW?; Initial SP value exchechsum DW, complement check value Exinitip DW? initial IP value Exinitcs DW? Initial CS value exreloctable DW? Reposition table byte offset Exoverlay DW?; Coverage number DOS, with the same name as EXE and COM, the runtime first executes the COM file. If you have only A.exe, you can enter a directly without entering the full name. However, if you have a.com and A.exe, enter a takes precedence over a.com, and to run A.exe you can only enter A.exe and cannot enter a. Typically used for DOS, executable files in Windows systems are typically. exe files. In MS-DOS, the file name extension used to identify the executable file. The user can run the executable program by pressing the ENTER key after entering the file name without the. exe extension, or by double-clicking on the prompt. File format
dos executable fileThe simplest executable file format that can be run in DOS and Windows. It is identified by adding the ASCII string "MZ" in the file header (represented as 4d5a in 16 binary). "MZ" is the initials of Mark Zberkowski (Mark Zbikowski), one of the MS-DOS developers.
16-bit new executable fileidentified by adding the ASCII string "NE" to the file header. It can only run on Windows and OS/2 systems, not under DOS.
16/32-bit executable fileidentified by adding the ASCII string "LE" to the file header. It is used only to replace VxD drivers in Windows 3.x and Windows 9x.
32-bit linear executable fileidentified by adding the ASCII string "LX" to the file header. Running in OS/2 2.0 and later, it can also be used for some DOS extensions.
32-bit executable fileThis is the most complex and currently the most popular executable file format, identified by adding the ASCII string "PE" to the file header. It operates primarily in Windows 95 and Windows NT, as well as later versions of Windows, and can also be run in BeOS R3.
64-bit executable fileSimilar to the previous one, but uses a central processing unit that supports 64 bits. So it can only run on 64-bit Windows systems, such as Windows XP 64-bit Edition and Windows Server 2003 64-bit Edition. Anti-compilation

Because inadvertently downloaded to the Trojan virus, the EXE file can not open, EXE is executable program file format, resulting in the open because of the EXE in the registry associated parameters have been maliciously modified, then how can we recover it?
Click Start, click All Programs, click Accessories, right-click Command prompt, Pop-up shortcut menu, click Properties
go to the interface of the Shortcut tab, click the Find Target button
Navigate directly to "%systemroot%\system32\cmd.exe", right-click on "Cmd.exe", open menu click "Rename", Change extension to "cmd", press ENTER
In the Command Prompt window, type "assoc. Exe=exefile" or "Ftype exefile="%1 "%*" command, then press ENTER and the ". Exe=exefile" appears after carriage return to indicate successful repair of executable program file associations
