Microsoft Lifecycle
We verify these against Microsoft's own end of support index pages on learn.microsoft.com (end-of-support-2026, -2027, -2029, -2032, -2034). All six agree except Windows 11 Enterprise LTSC 2024, which we correct here from 10 to 9 October 2029.

The IoT editions are not the desktop editions. Enterprise LTSC 2021 and IoT Enterprise LTSC 2021 are the same 19044 build, but the IoT SKU carries a 10 year lifecycle and the desktop SKU carries 5. A lane imaged with IoT Enterprise LTSC 2021 is good until January 2032; a lane imaged with plain Enterprise LTSC 2021 stops in January 2027. Confirm the SKU per lane before planning either as one migration.

Open known issues

Extended Security Updates now exist for LTSC 2016, and the IoT edition buys them from the hardware vendor, not from Microsoft. New
Microsoft's Windows IT Pro blog Plan for Windows Server 2016 and Windows 10 2016 LTSB end of support, published 20 Feb 2026 and last updated 21 Apr 2026, confirms end of support on 13 Oct 2026 for both Windows 10 Enterprise LTSB 2016 and Windows 10 IoT Enterprise LTSB 2016, and offers ESU for up to three years beyond it. The two editions are bought through different channels. Enterprise 2016 LTSB ESUs went on sale through Volume Licensing on 1 Apr 2026. ESUs for IoT Enterprise LTSB 2016 are available only through IoT OEMs, so for a lane the route is the device manufacturer, not a Microsoft volume agreement or a reseller quote. Price doubles each consecutive year and the years are cumulative: enrolling in year two means paying for year one as well. ESU carries critical and important security updates only, and explicitly does not extend technical support. Read 14 Sep 2026.
Remote Desktop Services may stop responding after the September update. New, mitigated
Opened 11 Sep 2026, last updated the same day. Originating update KB5122876, build 17763.9245. RDP connections fail after several minutes, sign in fails, and machines hang at "Please wait for the Remote Desktop Configuration". MMC, the RDS Licensing Diagnoser, File Explorer and the Windows Update page can go unresponsive with it. The affected list names Windows 10 Enterprise LTSC 2016, LTSC 2019, 21H2 and 22H2 as well as the Server editions, so this is not a server only problem. The only mitigation Microsoft states is stopping and restarting an affected virtual machine to restore connectivity, which is no help on physical lane hardware. Relevant where a lane accepts inbound RDP for support access.
The LTSC 2021 / 21H2 channel page still lists nothing open. Read with care
That page was last revised 14 Aug 2026 and shows only resolved entries: the Recycle Bin $Rxxxxx.ext delete dialog bug and the WSUS sync timeouts. The RDS issue above names 21H2 among its affected platforms but is filed on the 1809 and Server 2019 page, so a lane on 21H2 can be affected by an issue its own channel page does not carry.
False "Microsoft Defender Antivirus is turned off" notifications. Confirmed
Last updated 28 Aug 2026, not tied to a KB. Defender is running and every setting reads as active. The toast appears at sign in and intermittently after, and persists with notifications switched off. Microsoft lists every Windows and Windows Server version on current Defender platform updates, so this is not LTSC 2019 only. Fix is coming in a future Defender platform update. Verify protection state centrally, not from the toast.
Sources, and how to read this board
Epson Release note PDFs on download3.ebz.epson.net and the newer download-center.epson.com. The portal index pages are blocked by robots, the ov_*.pdf notes are not, and each carries version, upload date and changelog. Advisories at wa00971, wa00977, wa00828.
Zebra Two machine readable sources, no scraping in either. Software: techdocs.zebra.com, whose /about/ pages carry version history tables. Firmware: the quarterly Evolution Update notes. Those notes are fetchable; an earlier reading that they were not came from testing off site, where the CDN answers 406. Their urls are discovered from the json feed behind that page, because the filenames and directories have changed repeatedly and cannot be constructed. Note that an older release notes page also exists but stops at version 3.0 from 2016, so it is not a usable source.
Datalogic and HP Datalogic software downloads, server rendered, so a plain GET reads all 68 entries and the category query string is only a client side filter. In counter firmware is not published there or anywhere else on the open web, re-checked 13 Sep 2026. HP ships OPOS as separate per peripheral SoftPaqs, each with its own version, read through the HPCMSL reference file.

How to read this board Every version here was taken from a vendor page or release note, with the date that page showed. A Not verified chip means the vendor does not publish the figure publicly and it was left blank rather than guessed. Fiscal entries state the position as of 12 Sep 2026; confirm against the primary text before committing engineering work.
Opticon, Newland and Honeywell Opticon downloads is the most open source of the four scanner vendors: one server rendered page, a firmware level for every current model, no login. Newland software and drivers are public direct links whose versions come from the link label or the filename; only its Ndevor device management portal needs a login. Honeywell publishes nothing readable: every route ends at hsmftp.honeywell.com behind a sign in.

We read every version here from a vendor page or release note, and we publish this board because most of it is just as true for anyone else running tills. Where we cannot confirm a level at source we mark it Not verified rather than estimating it. Talk to us about a POS estate →

We publish this in good faith and check it at source, but vendor pages move and regulations change: we cannot warrant that everything here is complete or current, and Tillforge accepts no liability for decisions taken on the basis of this page. Anything acted on should first be confirmed with the vendor or the relevant authority. See our terms.
