In computing, regsvr32
(Register Server) is a command-line utility in Microsoft Windows and ReactOS [1] for registering and unregistering DLLs and ActiveX controls in the operating system Registry. [2] Despite the suffix "32" in the name of the file, there are both 32-bit and 64-bit versions of this utility (with identical names, but in different directories). [3] regsvr32
requires elevated privileges. [4]
To be used with regsvr32
, a DLL must export the functions DllRegisterServer
and DllUnregisterServer
. [5]
regsvr32 shmedia.dll
for registering a file
regsvr32 shmedia.dll /s
for registering a file without the dialog box ( silent )
regsvr32 /u shmedia.dll
for unregistering a file
regsvr32 shmedia.dll /u /s
for unregistering a file without the dialog box ( silent )
If another copy of shmedia.dll exists in the system search path, regsvr32 may choose that copy instead of the one in the current directory. This problem can usually be solved by specifying a full path (e.g., c:\windows\system32\shmedia.dll) or using the following syntax:
regsvr32 .\shmedia.dll
VBScript is a deprecated programming language for scripting on Microsoft Windows using Component Object Model (COM) based on classic Visual Basic and Active Scripting.
Visual DialogScript (VDS) is an interpreted programming language for Microsoft Windows, using dialog and graphic elements to create programs. VDS is similar to other programming languages such as Visual Basic, C++, or Delphi, as they use Windows API.
In computing, DLL hell is a term for the complications that arise when one works with dynamic-link libraries (DLLs) used with Microsoft Windows operating systems, particularly legacy 16-bit editions, which all run in a single memory space.
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs access API functionality via dynamic-link library (DLL) technology.
The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interfaces can all use the registry. The registry also allows access to counters for profiling system performance.
Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, eComStation, ArcaOS, Microsoft Windows, and ReactOS operating systems. On Windows CE .NET 4.2, Windows CE 5.0 and Windows Embedded CE 6.0 it is referred to as the Command Processor Shell. Its implementations differ between operating systems, but the behavior and basic set of commands are consistent. cmd.exe is the counterpart of COMMAND.COM in DOS and Windows 9x systems, and analogous to the Unix shells used on Unix-like systems. The initial version of cmd.exe for Windows NT was developed by Therese Stowell. Windows CE 2.11 was the first embedded Windows release to support a console and a Windows CE version of cmd.exe. The ReactOS implementation of cmd.exe is derived from FreeCOM, the FreeDOS command line interpreter.
In computing, XCOPY
is a command used on IBM PC DOS, MS-DOS, IBM OS/2, Microsoft Windows, FreeDOS, ReactOS, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network.
Shadow Copy is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service. A software VSS provider service is also included as part of Windows to be used by Windows applications. Shadow Copy technology requires either the Windows NTFS or ReFS filesystems in order to create and store shadow copies. Shadow Copies can be created on local and external volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point.
AutoRun and the companion feature AutoPlay are components of the Microsoft Windows operating system that dictate what actions the system takes when a drive is mounted.
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system.
System File Checker (SFC) is a utility in Microsoft Windows that allows users to scan for and restore corrupted Windows system files.
The Windows Metafile vulnerability—also called the Metafile Image Code Execution and abbreviated MICE—is a security vulnerability in the way some versions of the Microsoft Windows operating system handled images in the Windows Metafile format. It permits arbitrary code to be executed on affected computers without the permission of their users. It was discovered on December 27, 2005, and the first reports of affected computers were announced within 24 hours. Microsoft released a high-priority update to eliminate this vulnerability via Windows Update on January 5, 2006. Attacks using this vulnerability are known as WMF exploits.
In Windows NT operating systems, a Windows service is a computer program that operates in the background. It is similar in concept to a Unix daemon. A Windows service must conform to the interface rules and protocols of the Service Control Manager, the component responsible for managing Windows services. It is the Services and Controller app, services.exe, that launches all the services and manages their actions, such as start, end, etc.
The Microsoft Windows operating system supports a form of shared libraries known as "dynamic-link libraries", which are code libraries that can be used by multiple processes while only one copy is loaded into memory. This article provides an overview of the core libraries that are included with every modern Windows installation, on top of which most Windows applications are built.
Robocopy is a command-line file transfer utility for Microsoft Windows. Robocopy is functionally more comprehensive than the COPY command and XCOPY, but replaces neither. Created by Kevin Allen and first released as part of the Windows NT 4.0 Resource Kit, it has been a standard feature of Windows since Windows Vista and Windows Server 2008.
NTFS links are the abstraction used in the NTFS file system—the default file system for all Microsoft Windows versions belonging to the Windows NT family—to associate pathnames and certain kinds of metadata, with entries in the NTFS Master File Table (MFT). NTFS broadly adopts a pattern akin to typical Unix file systems in the way it stores and references file data and metadata; the most significant difference is that in NTFS, the MFT "takes the place of" inodes, fulfilling most of the functions which inodes fulfill in a typical Unix filesystem.
Windows Vista contains a range of new technologies and features that are intended to help network administrators and power users better manage their systems. Notable changes include a complete replacement of both the Windows Setup and the Windows startup processes, completely rewritten deployment mechanisms, new diagnostic and health monitoring tools such as random access memory diagnostic program, support for per-application Remote Desktop sessions, a completely new Task Scheduler, and a range of new Group Policy settings covering many of the features new to Windows Vista. Subsystem for UNIX Applications, which provides a POSIX-compatible environment is also introduced.
A batch file is a script file in DOS, OS/2 and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as IF
, FOR
, and GOTO
labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file might not process a batch of multiple data.
In computing, net
is a command in IBM OS/2, Microsoft Windows, ReactOS and Greentea OS used to manage and configure the operating system from the command-line. It is also part of the IBM PC Network Program for DOS.
In computing on Microsoft platforms, WoW64 is a subsystem of the Windows operating system capable of running 32-bit applications on 64-bit Windows. It is included in all 64-bit versions of Windows, except in Windows Server Server Core where it is an optional component, and Windows Nano Server where it is not included. WoW64 aims to take care of many of the differences between 32-bit Windows and 64-bit Windows, particularly involving structural changes to Windows itself.
