Windows Vista build 5439
|Build of Windows Vista|
Windows Vista build 5439 is a rumored unleaked build of Windows Vista. It has appeared in several build lists, but it is very unlikely to exist. The build tag comes from
hdaudbus.sys, which is the High Definition Audio Bus driver. This file has been confirmed to also exist with a buildtag resembling other build numbers, such as 5750 or 5840.16387. Therefore this build is very unlikely to exist. Mentions of build 5423 with this build tag have appeared in unconfirmed lists as well.
