Signing out closes your Windows session, which closes OBS and stops its stream. If you only need to secure the screen while you step away, use Windows key + L to lock the computer instead; that leaves your session and applications open, but does not guarantee OBS will keep rendering video.
For a broadcast that must continue unattended, test the exact computer and scene before relying on a locked or switched-away session. If the stream must run without an active Windows session, use a different operating arrangement rather than expecting a stream key or Windows setting to keep OBS alive.
Why signing out stops OBS
OBS is an application running inside your Windows user session. When you choose Sign out, Windows ends that session and closes its open applications. OBS therefore stops sending its output; the stream cannot continue simply because YouTube still has a stream key saved.
OBS’s own active-output warning makes the consequence clear: “OBS is still currently active. All streams/recordings will be shut down.” If that warning appears while you are exiting OBS, cancelling preserves the application for the moment; confirming exit shuts down active outputs. Signing out closes the session containing OBS, so it is not a way to leave the encoder running in the background.
This distinction matters when you are planning a long broadcast. A devotional playlist, local news loop or study stream may look as if it is just a video playing on a screen, but OBS is doing the work of composing sources and sending a live feed. Closing the application that performs that work interrupts the feed. A 24/7 playlist scheduler comparison can help you think about how a programme is assembled, but it cannot change what signing out does to a Windows session.
What Windows does to your open apps
Windows offers three actions that are easy to confuse: Sign out, Lock and Switch user. They have different effects on the session and on open applications.
| Windows action | What happens to the current session | What to expect from OBS |
|---|---|---|
| Sign out | Windows ends the session and closes its open applications. | OBS closes; its stream stops. |
| Lock | The session remains open and the screen is secured. | OBS stays open, but continued rendering is not guaranteed. |
| Switch user | Windows moves to another account without ending the original session. | OBS may remain open, but rendering while switched away is not guaranteed. |
Microsoft says that signing out closes open applications, while locking keeps applications and files open in the background. It also describes switching accounts as moving between users without closing applications or ending the current session. These are useful distinctions, but the statement that an application remains open should not be read as a promise that every part of its work continues normally.
A session can remain alive while the graphics conditions OBS needs change. That is why “OBS is still listed as running” and “YouTube is receiving a changing picture” are separate questions. Check the current Microsoft guidance on user account access in Windows if the exact labels or account controls differ on your Windows version.
Lock Windows when you need to step away
If you want to secure the display without intentionally closing your applications, press Windows key + L. Windows locks the current account and shows the lock screen. When you return, sign back in to the same account to see the desktop and OBS as you left them.
Locking is the appropriate first choice when the practical need is privacy: you are leaving the room, do not want someone at the keyboard, and can keep the computer in its existing session. It avoids the deliberate shutdown that occurs at sign-out. Do not treat it as a 24/7 streaming setting, though. A locked session can preserve an open OBS window while the scene or source output has stopped updating.
Before using this for a real broadcast, consider what else can interrupt the computer. Sleep, a restart, a power cut, a network failure or a graphics-driver problem may all stop the feed even if you used Lock rather than Sign out. Adjusting power behaviour may reduce one particular risk, but it does not convert Windows sign-out into a background-streaming mode. Keep a recovery plan that does not depend on assuming the picture is still live.
Why an open OBS window may not keep rendering
OBS does more than hold a window open. It has to render scenes from their sources and encode frames for transmission. Some sources rely on graphics access, and OBS needs to produce new output continuously for the viewers to see a moving or changing picture. The application can remain in the session even if the conditions for producing that output change.
An OBS Project forum reply reported that Windows may remove GPU access when the user session is switched away or the lock screen is active, leaving OBS unable to produce output in that situation. That is community guidance, not a current guarantee about every Windows build or graphics configuration. Behaviour can depend on the computer, drivers, OBS version, source types and the particular way the scene is rendered. Read the OBS forum discussion about switching Windows users as a reason to test, not as proof that every locked machine will freeze.
A scene made only from a prerecorded video may behave differently from one that includes browser sources, capture devices, animated graphics or other live inputs. That does not make one setup universally safe. A useful point of comparison is troubleshooting a visible output fault, such as green frames in pre-recorded video through OBS: a feed can connect to YouTube while the picture itself is wrong. Connection status alone cannot confirm that your intended programme is still being rendered.
Test your exact OBS and graphics setup
Test before a scheduled or important broadcast, using the same Windows account, OBS profile, scene collection, sources and graphics arrangement you intend to use. A test with a blank scene or a different computer tells you little about the setup you will rely on overnight. Use a private or unlisted test broadcast if that fits your channel’s needs, and confirm the current visibility and broadcast controls in YouTube before starting.
A practical test looks like this:
- Start OBS with the scene you expect to broadcast. Confirm that the preview contains the right picture and that OBS is sending output.
- Start a test broadcast and check the feed in YouTube Live Control Room. Confirm that YouTube is receiving the expected image and sound.
- Lock Windows with Windows key + L. Leave the test running for a period that is meaningful for your use, then sign back into the same account.
- Check OBS’s preview and output state, then inspect the actual YouTube feed. Look for a frozen image, missing sound, a disconnected encoder or a feed that has ended.
- If you expect to use Switch user, test that action separately. Do not infer its behaviour from a lock test; it changes the session’s foreground status in a different way.
A short successful check is evidence about that check, not a guarantee for a later night. Repeat after changes to Windows, graphics drivers, OBS, sources or scene composition. If a stream is important, decide what someone will do if the feed freezes or the computer restarts. You can also review OBS output details and logs after a test, and compare the picture seen in YouTube rather than relying only on an OBS status indicator.
For a dropped or frozen feed, separate the symptoms. If OBS is still producing output but YouTube is not receiving it, investigate the connection and encoder path. If OBS is connected but the image has stopped changing, examine rendering and sources. The OBS Help page explains that OBS connects directly from the computer to the streaming platform; bitrate and network stability can matter to dropped frames, but neither fixes a Windows session that has been closed.
A stream key is not a way around sign-out
YouTube’s stream key identifies the destination and allows YouTube to accept an encoder’s feed. It does not run the encoder or keep OBS open. YouTube describes stream keys as a password and address for the stream; the computer still has to send the video. See YouTube’s guidance on stream keys for the current explanation and interface.
This is why changing a key is not a remedy when signing out has stopped OBS. Nor does enabling YouTube’s auto-start or auto-stop control keep an application alive: those controls concern the broadcast state in relation to the incoming encoder feed. If OBS is no longer running, YouTube cannot receive new frames from it. When you return after an interruption, confirm both that OBS is sending and that the intended broadcast is active in Live Control Room before assuming the audience can see the programme.
Options for streaming without an open session
If the channel must continue while you are away, decide first whether the requirement is “keep this desktop session open” or “keep a live programme available without depending on this desktop session”. The first can be tested with Lock. The second calls for a different operating arrangement, with its own setup, monitoring and recovery plan.
One route is to run OBS on a computer that remains powered on and in the required active session, with someone or a monitoring process able to notice and recover from problems. That still depends on the machine, Windows session, graphics behaviour, network and power. It may suit a channel with a local operator, but it is not the same as signing out and expecting OBS to continue.
Another route is a continuously active, dedicated streaming environment or a hosted service that takes an uploaded programme and maintains the broadcast without your personal computer being left open. These approaches differ in how you prepare content, monitor playback and regain control after an interruption. For a Linux-based, self-managed route, the guide to setting up a 24/7 Krishna bhajan stream with OBS on Linux is a useful starting point for considering a separate environment, not a Windows sign-out workaround. A VPS reboot recovery guide covers a different failure mode: recovery after a reboot does not mean the feed is immune to every interruption.
Choose based on who will operate the stream and what kinds of failure you can manage. A self-managed environment gives you control over software and content flow, but you are responsible for testing and recovery. A managed arrangement can remove the need to leave your personal computer running; it still requires you to check the programme, channel configuration and feed. StreamNeo addresses the specific burden of leaving a personal computer on by taking an uploaded video and running it as a YouTube live stream, so the stream does not depend on keeping your own Windows session open.

FAQ
Can OBS keep streaming after I sign out of Windows?
No. Windows sign-out closes open applications in that user session, including OBS, so its output stops. A stream key does not keep the application running.
Does locking Windows guarantee the stream will continue?
No. Locking keeps the session and applications open, but rendering can still be affected by GPU access or other changes. Test your exact OBS scene and computer, then verify the feed in YouTube.
What is the difference between Lock and Switch user?
Lock secures the screen while leaving the current account session open. Switch user moves to another account without ending the first session, but OBS output while that session is in the background is not assured; test it separately.
What should I do for a 24/7 unattended stream?
Use an arrangement designed to operate without relying on your personal Windows session, and plan how you will monitor and recover it. Test the full programme and YouTube feed before relying on it for a continuous channel.
