The Wyse 3040 was Dell's entry-level ThinOS thin client, a very common VDI endpoint in government call centers, kiosks, and general-purpose desktop-virtualization deployments. Dell's official thin-client OS lifecycle document (as of July 10, 2026) lists end of marketing life on 2021-12-31, end of feature support on 2024-06-30, and end of service support on 2026-05-15, after which no further ThinOS software updates are issued.

Frequently asked
When is the Dell Wyse 3040 end of life?
Dell's published notice sets End-of-Sale for the Wyse 3040 at Dec 31, 2021. The published end-of-support date is May 15, 2026, after which vendor support ends. It is past its published support window — plan the refresh now.
What replaces the Dell Wyse 3040?
Dell has not named a one-for-one replacement in the notice this page is built from. Uniqcli can recommend and quote the current equivalent for the Wyse 3040, with TAA country-of-origin screening on request.
Can I still buy or get support for the Wyse 3040?
New units are no longer sold by Dell after the End-of-Sale date; remaining channel stock and refurbished units are the only sources. Vendor support has ended (May 15, 2026), so security fixes and hardware replacement from Dell are no longer available. For a fleet still running this hardware, the practical next step is a refresh plan — request a quote and we will price the current replacement.
Send unit counts or a bill of materials — we price the current replacement, confirm stock and TAA country of origin, and return one reviewed refresh quote.
