Windows for Workgroups 3.11 build 300 RC 1993-10-21

Windows for Workgroups 3.11 build 300 is a Release Candidate build of Windows for Workgroups 3.11 that was recompiled several times. This is a later recompile from 21 October 1993 that was scene leaked by the warez group High Voltage, who also leaked the earlier compile from 13 October 1993. The group replaced the VGA boot screen of this build with a heavily edited one that features their name.

This recompile was often refered to as "build 411" in the past, due to the highest version number 3.11.411 found in some files. This has since been proven to be inaccurate.
