Quick Assist ships with Windows, and for a one-off look at someone’s screen it’s fine. But the helper must sign in with a Microsoft account, there’s no file transfer, no unattended access, no reconnect — and when the remote PC needs a reboot, the session dies with it. DoorDast keeps the “it’s just built for helping” feel and removes the ceilings.

Where DoorDast is the better pick
- Regular help, not one-off help. Set an access password on Mom’s PC once, and next time you connect directly — no reading codes over the phone, no “click Allow” confusion. Our guide to remote support for family is built around exactly this.
- Fixes that need files. Drivers, installers, log files — Quick Assist can’t move a single byte. DoorDast has a real transfer queue.
- Fixes that need a reboot. DoorDast picks the session back up after a restart. Quick Assist makes you start the whole code dance again.
- No Microsoft account hurdle. Quick Assist requires the helper to sign in — a real barrier when you’re the one being helped and your helper isn’t a Microsoft user.
Where Quick Assist is the better pick
- Zero-install policy environments. It’s already on every Windows box — when installing anything is off the table, that decides it.
- Truly one-time favors. If you will genuinely never help this person again, built-in and forgettable is a fair trade.
For everyone you’ll help more than once: download DoorDast on their PC while you’re there (or talk them through the one small install), set an access password, and every future rescue is one click. Free, and end-to-end encrypted so the only people in the session are the two of you.
