Installation
The OS Loader has a bug during setup that it tries to load, but since   installs instead, it will be stuck on the OS Loader in an infinite loop. Editing the boot sector file to boot from   will allow setup to continue.

This can be done using any MS-DOS boot disk with. At the prompt, type  and change the first   in the file to. Save the file, remove the disk, restart and the installation should continue as usual. Note that this procedure isn't needed if one uses SCSI.

This build also cannot be upgraded from Windows NT 4.0 with. If upgraded, during the text mode setup it will request for the Windows NT 4.0 CD, and then when the Windows NT 4.0 CD is inserted, the setup instantly crashes with IRQL_NOT_LESS_OR_EQUAL.

Windows Explorer
Windows Explorer doesn't have a very good graphics rendering engine as there is a graphical bug where anything dragged over Explorer windows will remain on the background of the Explorer window. This does not affect folders with custom background. Disabling Web View (by setting to "Display standard appearance" in the View tab in Options dialog from View menu) fixes this problem.
