How to create the registry key to restrict access to the registry

The Security permissions set on this key define what Users or Groups can connect to the system for remote Registry access. The default Windows installation defines this key and sets the Access Control List to restrict remote registry access as follows:

Administrators have Full Control
The default configuration for Windows permits only Administrators remote access to the Registry. Changes to this key to allow users remote registry access require a system reboot to take effect.

1. Start Registry Editor (Regedt32.exe) and go to the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
2. On the Edit menu, click Add Key.
3. Enter the following values:
Key Name: SecurePipeServers
Class: REG_SZ
4. Go to the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers
5. On the Edit menu, click Add Key.
6. Enter the following values:
Key Name: winreg
Class: REG_SZ
7. Go to the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg
8. On the Edit menu, click Add Value.
9. Enter the following values:
Value Name: Description
Data Type: REG_SZ
String: Registry Server
10. Go to the following subkey.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg
11. Select "winreg". Click Security and then click Permissions. Add users or groups to which you want to grant access.
12. Exit Registry Editor and restart Windows.
13. If you at a later stage want to change the list of users that can access the registry, repeat steps 10-12.

How to fix OS/2 Family API Calls Problems

This post provide computer help, If windows does not support OS/2 Family API.Windows and Windows 95 do not support 16-bit Windows-based applications coded with OS/2 Family API (FAPI) calls. To fix this error follow the instruction.

FAPI works in the following manner:

1. The code contains references to OS/2 FAPI calls (such as DosOpen, DosRead, and so on).
2. When the program is loaded into OS/2 protected mode, the system loader dynamically links the FAPI calls to the OS/2 system-services DLLs (Dynamic-Link Libraries).
3. When the program is loaded into real mode (MS-DOS or OS/2 compatibility box), what actually gets loaded is a small program called the "FAPI Loader and Linker." It is this program that loads the real code; it dynamically links the FAPI calls to a special library of support routines that translate FAPI calls into 80x86 code and MS-DOS interrupts (INT 21H Function xx).


FAPI works well for programs that need to run in MS-DOS and OS/2 protected mode. The problem is that Windows uses the "New EXE Format" for programs, bypassing the standard MS-DOS entry point. For example, if a Windows program is run outside of Windows (in MS-DOS), the following message appears, and the program terminates:

This program requires Microsoft Windows

MS-DOS is not responsible for this message; the Windows program itself is responsible. The way the Windows program works is very similar to OS/2: it uses dual entry points into the .EXE file. In MS-DOS, a short program that prints the above message runs; however, in Windows, a true Windows-based application runs using the other entry point in the .EXE file.

Therefore, the problem is narrowed down to the following: if the FAPI Loader and Linker program is run using the standard MS-DOS .EXE file entry point, and Windows starts an application using a different entry point, the dynamic linking of the FAPI routines will not occur.

To avoid this problem, do the following:

Instead of using low-level MS-DOS calls (INT 21H Function xx) in a Windows-based application and OS/2 API calls (DosRead, DosOpen, and so on) in a Presentation Manager (PM) application, use the C run-time I/O routines for all of these applications.

This will work because the Microsoft C Compiler and the run-time libraries supply versions of the libraries that work in both OS/2 and MS-DOS. By moving C code to PM and to Windows, it will not be necessary to rewrite it, and the appropriate conversion routines will be supplied at link time.
