So as today... Tech Bench ISO's are updated to 1511 (Feb 2016) versions.... I just checked it a couple of minutes ago.... downloaded an ISO from tech bench and sha1 checked it. So..... No need of unofficial mirrors anymore right? like the ones in this thread.
And don't forget to mention the download speed, sometimes MS servers are (to) busy it seems lately As today? it has been updated weeks ago
You are asking that in the latest build thread? Serious, this is the latest build from MSDM/VSLC (1511.1 or 10586.103 or 1511 feb updated 2016) but an updated 1511 installs a newer build.
