SUMMARY
Windows NT may occasionally stop responding (hang) when the ALT+F4+F6
keys are pressed simultaneously for a 16-bit Windows-based
application. If these keys are pressed while the application is being
loaded, a system failure may occur. A failure can also occur when you
choose Save As from the File menu and press ALT+F4+F6 when new data
has not been saved. Windows-based applications such as Microsoft Word
for Windows, version 2.0a, and Microsoft Excel can also produce these
failures. This problem is most common on keyboards that have the
function keys located on the left side of the keyboard, in which case,
the F4 and F6 keys may easily be pressed simultaneously by accident.
CAUSE
WOWEXEC produces a kernel-level failure through the Windows NT 32-bit
subsystem.
RESOLUTION
An updated WINSRV.DLL file corrects this problem (on Intel x86
Microsoft Windows NT 3.1 installations). This file is available
through Microsoft Electronic Services including CompuServe (WINNT
forum Library2: Patches and Updates) and the Internet
(GoWinNT.Microsoft.Com: Bussys\winnt\unsup-ed\fixes\WinSrv\*.*). The
file available on these services, WINSRV.EXE, is a self-extracting
archive.
To replace the WINSRV.DLL file, do the following:
WARNING: If this file becomes corrupt when installed on NTFS, the
system may fail to start. If possible, test this file on
a FAT partition of a test system.
- Rename WinNT\System32\WINSRV.DLL *.old.
- Copy WINSRV.DLL WinNT\System32.
- Shut down the system and then restart it.
This replacement file is provided as is, and is not supported by
Microsoft Product Support Services. A tested and supported copy of
this file will be included in an updated Microsoft Windows NT Service
Pack.
