Installation

 * When installing from DOS or Windows 95 using either  or   and not booting from the CD, 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. You can also use Notepad to edit the file. Note that this procedure isn't needed if the hard disk type is set to SCSI.


 * When upgrading from Windows NT 4.0 or build 1515.1 with, 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. To upgrade seamlessly, check the "Copy files from CD-ROM to the hard drive" option in "Advanced Options".


 * Due to ActiveMovie being included in this build, the Windows NT EULA has been overwritten with the ActiveMovie one.

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.
 * Most Accessories shortcuts are gone in this build, although most applications are still present and can be launched using the Run command.
