Hi folks, Ned here again. This blog post contains all products requiring SMB1, where the vendor explicitly states this in their own documentation or communications. This list is not complete and you should never treat it as complete; check back often.

To update this list, please email StillNeedsSMB1@microsoft.com or tweet @nerdpyle with hashtag #StillNeedsSMB1.
Adding a product to this list requires direct quote or documentation from the vendor of that product, including their website, knowledgebase, support forums, or other vendor channels; third party forums are not enough to qualify. Consult your vendor for updates and newer product versions that support at least SMB 2.02. If you are a vendor and wish to report requirements for SMB1 or if information above has changed, email StillNeedsSMB1@microsoft.com.
There are vendors who are not publishing their SMB1 requirements. It is up to you, their customer, to have them publish this information – Microsoft cannot make them do so. If a vendor does not state if they require SMB1 but you believe they do, please contact that vendor directly. If you need assistance getting a vendor response, email StillNeedsSMB1@microsoft.com and we will try our best to assist. Politeness works best; the person you are speaking to at a vendor is extremely unlikely to have put SMB1 into the product & probably isn’t any happier about it than you are!
For more information on why using SMB1 is unsafe, see StopUsingSMB1. SMB1 has been deprecated for years and will be removed by default from many editions and SKUs of Windows 10 and Windows Server 2016 in the RS3 release.
Be safe out there,
Ned Pyle, Principal Program Manager of the SMB protocol family at Microsoft
