Windows - Required

   

Files Required by Windows versions

   
          ** XP also applies to Vista (Windows 7 is unknown)
  File     Versions What are they for
  %sysdir%\stobject.dll XP It's used to manage system tray.
  %windir%\explorer.exe 95 98 ME NT 2K XP Windows shell.

This creates a database of the application programs you use and which files they load. The information is used by Windows Defrag (and by Norton Speedisk) to optimize the location of files on your hard drive so that Windows startup and program loading is faster.

  afvxd.vxd  

Microsoft TDI transport service provider. Supports TCP/IP-specific functionality for Microsoft TDI transport service provider for Windows Sockets 2.0.

  alerter  

Notifies selected users and computers of administrative alerts. If the service is stopped, programs that use administrative alerts will not receive them. If this service is disabled, any services that explicitly depend on it will fail to start.
*If you are connected to a network, set it to Automatic. This service will notify your System Administrator of problems occurring within the network which may aid them in fixing the problem. http://www.beemerworld.com/tips/services...

  grpconv.exe   Microsoft group converter.
Used by installers ONLY in the RunOnce keys.
  hhctrl.ocx   hhctrl.ocx is the Microsoft HTML Help component. I think
you've installed a program that using HTML help. To use hhctrl.ocx it
must be registered in the system. Usually the installer uses RunOnce
keys to register hhctrl.ocx.

the hhctrl.ocx to be sure that you have the working version.
  ifsmgr 95/98/Me File system manager driver.
  int13 95/98/Me BIOS hard disk emulation driver.
  internat.exe   Language indicator. Microsoft Corporation.
Useful in the multi language Windows.
  ios 95/98/Me I/O Supervisor driver.
  ios.vxd   Many Windows 95 driver models, such as IOS (for disk drivers) and the network, support dynamically loaded device drivers. These VxDs are not loaded by the VMM32 real-mode loader, but are loaded by a device loader that is responsible for loading and initializing the drivers at the correct time and in the correct order.
For example, for SCSI adapter miniport drivers, the device loader is *IOS. The entries for a SCSI adapter are found in this Registry key:
Hkey_Local_Machine\System\CurrentControlSet\Services\Class
Because there is no StaticVxD=xxx line in this Registry entry, the VMM32 real-mode loader does nothing when Windows 95 identifies this device.
Configuration Manager attempts to find any device node that has a DevLoader= entry in the Registry. The device loader (in the previous example, *IOS) examines the Registry, finds the PortDriver= entry, loads the driver and any associated support drivers, and initializes the adapter.

  svchost.exe NT 2K XP Svchost.exe (Windows NT/2000/XP) is a generic host process name for services that are run from dynamic-link libraries (DLLs). The Svchost.exe file is located in the %SystemRoot%\System32
folder. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. There can be multiple instances of
Svchost.exe running at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where
Svchost.exe is started. This allows for better control and debugging.
