Download UltraDesk

Two ways to run it — both are built by Spectra Technologies India Private Limited. Install it as a service for machines you manage, or run the no-install portable for quick, one-off support.

Quick support

Portable — no install

Double-click and go. Nothing is installed permanently.

  • The AnyDesk/TeamViewer-style quick-support experience
  • Best for one-off attended sessions
  • Runs from Downloads; leaves no service behind
  • Still shows explicit consent + the always-on session indicator
Download portable (.exe)

Installer — service mode

Full install for managed, always-on access.

  • Best for machines you manage / unattended access
  • Installs as a Windows service, survives reboots
  • Shows as “UltraDesk” in Add/Remove Programs
  • Per-account permissions + full audit trail

⚠️ You may see a Windows security warning — that’s expected right now

This build is self-signed while our verified (EV) publisher certificate is being issued, so Windows SmartScreen may say “Windows protected your PC — unknown publisher.” Click More info → Run anyway to continue. It’s a genuine UltraDesk file: verify the SHA-256 below before you run it (Get-FileHash <file> -Algorithm SHA256) so you know it wasn’t tampered with. The signed, warning-free build follows shortly.

🔐 Verify your download (recommended)

Both downloads pass Windows Smart App Control and SmartScreen once published under our verified publisher identity. A macOS and Linux client are on the roadmap — ask sales about timelines.
