About dialog

Windows 95 build 323 is a Japanese beta build of Windows 95. However, it is in English but with Japanese IME support and language pack installed. This build removed the Non-disclosure agreement from Setup included since build 73f.

New features[edit | edit source]

This is the earliest available build to include "The Microsoft Network", along with a shortcut to it on the desktop.
This is the earliest available build to include support in Setup for the licensing scheme (product keys, etc.) used in the RTM. Interestingly, the non-OEM product key is only seven digits long at this point in development, rather than the ten digits that would end up being used.
- The internal structure in SUWIN.EXE used for ProductType configuration has two extra elements: a far pointer to a function used to generate a product identification number, and a far pointer to a function used to check the product key.
  - There are four different functions pointed to for both of the function pointers: one set for retail non-upgrade (ProductType 1,3,4,5); one set for retail upgrade (ProductType 2,6); one set for OEM floppy (ProductType 7,8); one set for OEM CD (ProductType 9).
- Writing the entered name and organisation to the boot sector of disk 2 has not yet been implemented. Setting setuppp.inf\data!TestPIDWrite to 1 will show the error message for when that write fails.
- The algorithm for the seven-digit key is the same as the last seven digits of the 10-digit key: all the digits added together most be divisible by 7.

Quirks[edit | edit source]

The Nature, Musica, Robotz and Utopia sound schemes are missing.

Additional files[edit | edit source]

This build is not packed into CABs (although an oversized PRECOPY1.CAB is present along with correctly sized MINI*.CAB files), but is an extracted folder dump like in build 99 and prior. It appears to have been copied directly from a build system at Microsoft at the time, as additional files are present:

LAYOUT.CSV is a comma-separated-value spreadsheet (including Microsoft Excel formulas) that presumably was used to generate LAYOUT.INF.
- Descriptions for each file are included. Some of them are interesting, for example WINMINE.EXE has a description of Cool Mine Sweeper Game.
There are several variants of SETUPPP.INF:
- SETUPPP.FLP (presumably for the floppy disk version of this build)
- SETUPPP.CD (presumably for the CD version of this build)
- SETUPP.CDA (same as previous but also including the "Microsoft Expo stub (CD only)").
