WARNING: Using Registry Editor incorrectly can cause serious, system-wide 
         problems that may require you to reinstall Windows NT to correct 
         them. Microsoft cannot guarantee that any problems resulting from 
         the use of Registry Editor can be solved. Use this tool at your 
         own risk.
 
SUMMARY
=======
 
When a shell other than Program Manager (PROGMAN.EXE) is being used,
the run and load entries in the registry might be ignored.
 
MORE INFORMATION
================
 
A common way to run or load applications at startup in Windows 3.x is
to add the filename to the load= or run= line in the WIN.INI file.
Windows NT translates these entries to the following registry key and
values:
 
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
  load: REG_SZ
  run: REG_SZ
 
They operate exactly the same as in Windows 3.0 and 3.1 as long as
Program Manager is used as the shell; however, if a replacement for
Program Manager is specified in

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT
   \CurrentVersion\Winlogon - Shell 

any programs set to load automatically (through the load value, run
value, or the Startup group) when Windows NT is started, it will not
load unless the third-party shell is written to search for such
values.
 
Steps to Reproduce Problem
--------------------------

 1. Start Registry Editor, REGEDT32.EXE.

 2. Select HKEY_CURRENT_USER\Software\Microsoft\Windows NT
    \CurrentVersion\Windows.

 3. In the Value window, double-click Load to open String Editor.

 4. Type the following and then press ENTER:

       clock 

    Choose OK.

 5. Quit Registry Editor and log off from Windows NT.

 6. Log on as the same user and notice that Clock appears in the
    lower-left corner.

 7. Start Registry Editor again.

 8  Select HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\
    CurrentVersion\Winlogon.

 9. In the Value window, double-click Shell to open String Editor.

10. Type the following and then press ENTER:

       winfile,taskman,wowexec

    Choose OK.

11. Quit Registry Editor and log off from Windows NT.

Logon as the same user and notice that File Manager comes up as the
shell, but Clock does not appear.
 
To return the system to its previous state, repeat steps 1-4 and 8-11,
removing "clock" on step 4 and entering "progman,wowexec" in step 10.
