Windows 98 build 1564

Windows 98 build 1564 is an unconfirmed build of Windows 98. There is very little information known about this build, other than that it was apparently scene leaked by the warez group Legendary on 1 August 1997, and was also mentioned in the Death Volume 25 warez CD list.

Due to the date it was leaked (build 1559, the latest preceding build confirmed to exist, was compiled on 4 August 1997), it is likely a mislabel of build 1546. It could also be the case, that the exact pre-day was unknown (Legendary pred the build sometime in August 1997), and a placeholder day was inserted (predbs tend to use a common RDBMS with datetime type, like MySQL, and it is assumed that the release date is known in full, leaving edge cases like this unhandled).

The list of a Traditional Chinese warez CD called "超級大補帖 １００" contains the (assumed) zh-TW version of this build ("CWIN98      Microsoft Windows 98 中文版 BUILD 1564").
