The best thing about Quick Assist is zero friction deployment for ad-hoc support ,working across a hybrid fleet of roughly 300 endpoints getting non technical remote user into a session takes less than 30 seconds .telling them to hit Ctrl+Win+Q opens prompt natively without sending them links or walking them through 3rd party ex. file.

From administrator side the screen redrawing is fast enough over basic broadband and built in laser pointer and annotation tools makes it easier to guide user visually rather than just taking over their mouse . It gives you screen control and basic elevated access when needed across the massive license cost of dedicated remote support platforms Review collected by and hosted on G2.com.

The biggest frustration comes from the administrative side after Microsoft shifted from an os integrated app to Store app. if you manage the device using Intune or group policy where store is locked down ,users without local admin rights often get stuck when the app require an update before starting the session.

It also lacks features for tier 2 or tier 3 support :

NO native file transfer during a live session.

Minimal audit logging and no granular Role-Based-Access Control If you need compliance logs showing exactly who remoted into what machine and when. Review collected by and hosted on G2.com.
