Windows NT 3.5 build 807 (Korean Beta)

Windows NT 3.5 build 807.1 (Korean Beta) is a Korean language build of Windows NT 3.5. It includes some Korean language applications, installs the Korean language pack, and has some changes in the setup.

Similarly to the Japanese language compile of Windows NT 3.5 build 756.1, an early concept of a timebomb is present in this build, where a dialog reminding the user to obtain a retail copy of Windows NT 3.5 is brought up by the system. The build is still normally usable in this state, however.
