WinBox is MikroTik's Windows utility for managing RouterOS devices. Around 2024 MikroTik released WinBox 4 — a full rewrite with a new interface — and in 2026 removed the classic version from its main download page. Many network engineers still prefer legacy WinBox 3: it is smaller, snappier, and keeps the familiar layout the MikroTik world used for over a decade.
This site hosts WinBox 3.43, the final release of the 3.x line (October 2025). The files are unmodified official MikroTik builds — verify the checksums below against any other source, including MikroTik's own archive. WinBox 3.43 manages both RouterOS v6 and current RouterOS v7 devices.
Actually looking for WinBox 4?
The new WinBox 4 is free from MikroTik directly at mikrotik.com/download — current, official, and updated with every release, so it needs no mirror. And if you were searching for WinBox 3.44 or 3.45: they don't exist. 3.43 is the final WinBox 3, and keeping it available is all this site is for.
Verify your download
Fake WinBox binaries are a known malware vector, so never trust a mirror
blindly — including this one. Check the SHA-256 checksum after downloading
(PowerShell: Get-FileHash winbox64.exe) and compare it to the official values:
| File | Size | SHA-256 | Scan |
|---|---|---|---|
| winbox64.exe | 2,295,976 bytes | 5b41cf51fd81e8d082687f6b522159cf4aba22e6df8edc486721d4e09507b6e9 |
VirusTotal |
| winbox.exe | 1,783,976 bytes | a4038e4e09a34285c8da8d8c2930ee38ea5beead2b6ffcd60130cdc8030e2e6b |
VirusTotal |
These checksums are identical to the files MikroTik serves from its own archive at download.mikrotik.com/routeros/winbox/3.43/ — same bytes, different server.
Frequently asked questions
Is this the official WinBox?
The files are unmodified official MikroTik builds — the SHA-256 checksums above match MikroTik's own 3.43 archive files exactly, and you can verify that yourself. The site itself is an independent mirror, not affiliated with MikroTik.
Why use WinBox 3 instead of WinBox 4?
WinBox 4 is a complete rewrite with a new interface. The classic WinBox 3 is lighter, faster to navigate, and keeps the layout MikroTik engineers have used for over a decade. If you manage routers all day, familiarity is speed.
Does WinBox 3.43 work with RouterOS v7?
Yes — it manages both RouterOS v6 and current RouterOS v7 devices, and is used daily against RouterOS 7.20+ without issues. Brand-new RouterOS features may only be exposed in WinBox 4 going forward.
64-bit or 32-bit — which one do I need?
The 64-bit build (winbox64.exe) on any modern Windows 10/11 machine —
that's almost everyone. The 32-bit build (winbox.exe) is only for old 32-bit
Windows installations.
Is WinBox 3 still updated?
No. Version 3.43 (October 2025) is the final WinBox 3 release — the 3.x line is end-of-life and no longer receives updates or security patches. Active development continues in WinBox 4 at mikrotik.com.
Can I still get WinBox 3 from MikroTik directly?
It's no longer on MikroTik's main download page, but at the time of writing their archive server still hosts the identical files (see the verify section above). This mirror exists because the legacy version has become genuinely hard to find.
