+** Emacs on Windows 9X requires UNICOWS.DLL
+
+If that DLL is not available, Emacs will display an error dialog
+stating its absence, and refuse to run.
+
+This is because Emacs 24.4 and later uses functions whose non-stub
+implementation is only available in UNICOWS.DLL, which implements the
+Microsoft Layer for Unicode on Windows 9X, or "MSLU". This article on
+MSDN:

+
+includes a short description of MSLU and a link where it can be
+downloaded.
+
+** A few seconds delay is seen at startup and for many file operations
+
+This happens when the Net Logon service is enabled. During Emacs
+startup, this service issues many DNS requests looking up for the
+Windows Domain Controller. When Emacs accesses files on networked
+drives, it automatically logs on the user into those drives, which
+again causes delays when Net Logon is running.
+
+The solution seems to be to disable Net Logon with this command typed
+at the Windows shell prompt:
+
+ net stop netlogon
+
+To start the service again, type "net start netlogon". (You can also
+stop and start the service from the Computer Management application,
+accessible by right-clicking "My Computer" or "Computer", selecting
+"Manage", then clicking on "Services".)
+
+** Emacs crashes when exiting the Emacs session
+
+This was reported to happen when some optional DLLs, such as those
+used for displaying images or the GnuTLS library, which are loaded
+on-demand, have a runtime dependency on the libgcc DLL,
+libgcc_s_dw2-1.dll. The reason seems to be a bug in libgcc which
+rears its ugly head whenever the libgcc DLL is loaded after Emacs has
+started.
+
+One solution for this problem is to find an alternative build of the
+same optional library that does not depend on the libgcc DLL.
+
+Another possibility is to rebuild Emacs with the -shared-libgcc
+switch, which will force Emacs to load libgcc_s_dw2-1.dll on startup,
+ahead of any optional DLLs loaded on-demand later in the session.
