Screen sharing and remote control solve different problems. To present a document, use a meeting app and share one window. To help someone operate a computer, use an assistance tool with their permission. To reach your own PC later, configure remote access deliberately. Choose the task before choosing the software.
Compare the main options
| Tool | Good starting use | Limit to know |
|---|---|---|
| Windows Quick Assist | Helping another Windows user in an attended session | The person shares the screen and separately approves requested control |
| Chrome Remote Desktop | Remote support or reaching your own supported computer | Support codes and persistent remote-access setup are different modes |
| Zoom | Presentations and group screen sharing | Workplace Basic meetings have a 40-minute limit |
| AnyDesk | Remote-control workflows across supported platforms | Free use is personal, non-commercial; work use needs a license |
Pick a tool in three steps
- Only showing something? Start with your existing meeting app and share the relevant window.
- Helping someone at their PC? Use an attended support session and explain the permissions before connecting.
- Reaching your own PC while away? Set up unattended access in advance and test it before you leave.
In Zoom’s current time-limit guidance, most meetings hosted with a Basic license end after 40 minutes. Check the host’s actual license rather than assuming a paid company account removes that limit for everyone.
Use Quick Assist for Windows help
- Both people open Quick Assist; install its official Microsoft Store version if needed.
- The helper selects Help someone and gives the generated code to the person receiving help.
- The recipient enters the code and approves screen sharing.
- If control is needed, the helper requests it and waits for separate approval.
- End the session when the task is finished.
Microsoft’s Quick Assist instructions document this consent flow. Use it with someone you contacted and trust; a code request from an unsolicited caller is not a reason to grant access.
For ordinary help between friends, Quick Assist is a Windows option. Microsoft’s macOS version is reserved for sessions with Microsoft Support, so do not recommend it as a general Mac-to-Mac support app.
Use Chrome Remote Desktop in the correct mode
For one-time help, generate a support code and check the helper’s identity before accepting access. For your own computer, use the remote-access setup, its PIN and the required operating-system permissions. The host must be available; installing the viewer does not make a sleeping or disconnected PC reachable.
Google’s setup guide covers Windows, Mac and Linux hosts. Do not leave persistent access enabled on a shared machine simply because a support session needed it once.
Use Zoom for showing, not handing over
Share the specific app window when you only need to present. Check notifications and close unrelated files first. Remote-control permissions are separate from displaying a screen. Confirm the current Zoom plan for meeting duration and participant limits; a free meeting tool is not unlimited conferencing.
Check AnyDesk and Windows Remote Desktop requirements
AnyDesk’s license guidance distinguishes helping friends or personal devices from work, paid support and job-related access. Do not assume its free edition covers a business workflow.
Windows Remote Desktop is a different hosting arrangement: supported Pro/Enterprise editions can host connections, while Home is not a standard RDP host. Use a properly managed network or VPN arrangement rather than exposing a remote-desktop port directly to the internet.

Frequently asked questions
What is a good free screen-sharing tool for Windows?
Quick Assist is a straightforward choice for helping a trusted person who is at their Windows PC. For a presentation, a meeting app may be enough. Chrome Remote Desktop is another option when you need its supported remote-access or support modes.
Is screen sharing the same as remote control?
No. A view-only presentation shows your screen or window. A remote-control session can let the other person operate the computer. Check the tool’s permission prompt: Chrome Remote Desktop support, for example, grants broad access when you accept the session.
Can I connect when the remote PC is switched off?
Not through an ordinary screen-sharing session. The host needs power, a working internet connection and the required host software running. Sleep, firewall rules, account policies and missing operating-system permissions can also prevent a connection.
