On Windows, you can launch OBS at sign-in by placing a shortcut in the Startup folder or by creating a Task Scheduler task. Add OBS’s --startstreaming argument, then enable Auto-start separately for the scheduled YouTube broadcast if you want it to go live when OBS begins sending video.
These are connected steps, not a guarantee of unattended recovery. OBS starting, OBS connecting to YouTube, and YouTube making a broadcast live are distinct events; a power, software or network failure can interrupt any of them. Test the full sequence on your own channel before relying on it overnight.
Prepare OBS and its YouTube connection
First, get a normal manual stream working. Open OBS with the scene and profile you intend to use, and confirm that its output settings suit the material. If you are looping a recorded programme, check the source, audio and transitions as well as the encoder settings. A launch argument cannot correct a missing media file, a muted source or a profile that is not the one you expected.
In OBS, set up the YouTube encoder connection with the Live server URL and stream key provided through YouTube’s live setup. YouTube describes the encoder connection details in its live streaming with an encoder instructions. Follow the current Studio flow for your channel: interface labels and broadcast options can change.
Treat the stream key as a credential. Anyone who can use it may be able to send a broadcast to the associated channel, so do not put it in a public screenshot, a shared task description or a document that other people can access. If you need to understand what the key does before configuring it, see this guide to using a YouTube stream key with OBS. If you think a key has been exposed, check YouTube Studio and rotate it there rather than assuming a new Windows shortcut has fixed the issue.
Before adding automation, start streaming from OBS manually and inspect the result in YouTube Studio. Confirm that the correct account and broadcast are involved, that the intended picture and sound arrive, and that YouTube has the state you expect. Stop the test when finished. This baseline matters: later, when something fails, you need to know whether the fault is in OBS startup, the connection, or YouTube’s broadcast controls.
Choose a Windows sign-in method
There are two practical ways to launch OBS when a Windows user signs in. A Startup-folder shortcut is simple to set up and easy to inspect. Task Scheduler gives you more control over when a task runs, but it introduces more settings to check. Neither option makes a powered-off computer turn itself on, nor does a sign-in trigger necessarily cover every situation in which Windows restarts.
| Method | What happens | Useful when | Trade-off |
|---|---|---|---|
| Startup folder | Windows launches the shortcut for the signed-in user | You can sign in normally and want a simple setup | It depends on that user signing in |
| Task Scheduler | Windows runs a configured task according to its trigger and options | You need more control over the launch | More configuration means more ways to choose an unintended trigger or launch context |
For the Startup folder route, press Windows key + R, enter shell:startup, and press Enter. Put a shortcut to OBS in the folder that opens. This is the user’s Startup folder, so the shortcut is associated with that account’s sign-in. If the PC reaches the sign-in screen after a reboot but nobody signs in, do not assume this method has started OBS.
For Task Scheduler, create a task that launches the OBS executable at the sign-in event you actually intend to use. Set the action to start the OBS program, and include the launch argument described in the next section. OBS’s guidance for scheduled or other automated launches also calls for a working directory pointing to the folder containing obs64.exe; set that as the task’s “Start in” location. See the OBS launch parameters documentation for the project’s instructions. Avoid copying settings from another computer without checking where OBS is installed on yours.
The choice is about the relationship between simplicity and control, not which method can promise continuous service. For a home devotional channel where someone signs into a dedicated Windows account after restart, the Startup folder may be enough. If you need a more deliberate task trigger or a working-directory field, Task Scheduler is worth the extra checks. First decide whether a person will sign in, then choose the method that matches that real operating routine.
Add the OBS launch argument
OBS documents --startstreaming as a launch parameter that tells OBS to begin streaming when it starts. It asks users launching through scheduled tasks or other automated means to set a working directory as well. That argument starts OBS’s streaming action; it does not create a YouTube scheduled event, choose an event for you, or instruct YouTube to bypass its own broadcast controls.
With a Startup shortcut, open its Properties and find the Target field. Keep the existing executable path intact, then add a space followed by --startstreaming after the closing quotation mark. The result should follow this pattern:
"C:\Path\To\obs64.exe" --startstreaming
Use the actual path on your computer. Do not replace the path with the example, and do not put the argument inside the quotation marks that belong around a path containing spaces. If Windows reports that the target is invalid, check the quotation marks and spacing before changing the OBS installation.
With Task Scheduler, put --startstreaming in the action’s arguments field rather than appending it to the executable name. Put the folder containing obs64.exe in the “Start in” field, without adding the executable filename there. This separates the program Windows should run from the argument OBS should receive and the working directory it should use.
Make only one launch route responsible for starting OBS while you test. If both a Startup shortcut and a scheduled task launch it, you can get two launch attempts or confusing results depending on how OBS handles an already-running instance. Keep notes of which route you enabled, and disable the second route unless you have a specific reason to keep it.
Enable YouTube Auto-start for the scheduled broadcast
OBS’s launch argument and YouTube’s Auto-start are separate controls. The argument asks OBS to begin sending its encoder output. For a scheduled broadcast, YouTube’s Auto-start setting determines whether the broadcast goes live as OBS starts sending. If Auto-start is off, an encoder can be connected without YouTube automatically making the scheduled broadcast live; you may still need to press Go Live in Studio.
Open YouTube Studio and inspect the scheduled broadcast you intend to use. Enable Auto-start there if that is the behaviour you want, and verify the setting on the actual broadcast rather than assuming the OBS profile controls it. Check YouTube’s current instructions for creating a live stream with an encoder because Studio’s wording and available workflow can change.
Do not infer that --startstreaming will select the right event or create a fresh event after every restart. The OBS parameter starts its streaming action; the scheduled broadcast and its YouTube settings are separate. A channel that uses scheduled broadcasts should confirm which broadcast is active and what its state is before trusting an automatic sequence.
If Auto-start is not suitable for your channel’s workflow, plan for a person to check Studio and take the required action. For example, a local news loop may need an operator to confirm that the correct scheduled programme is live, while a simple ambient loop may use one recurring broadcast process. In either case, the control in YouTube does not replace checks on the OBS scene, stream key or incoming video.
Test a sign-in launch before depending on it
Save the shortcut or task, then test the sequence deliberately. Close OBS, sign out of Windows, and sign in to the same account used by the Startup shortcut or task trigger. Observe whether OBS opens, whether it loads the expected scene and whether it begins streaming. Then check YouTube Studio and the viewer-facing stream to confirm the intended broadcast—not merely an OBS window—is live and showing the right content.
Keep the first test supervised. If the stream goes live unexpectedly, you should be there to stop it. If OBS opens but does not transmit, investigate the OBS connection and launch settings. If OBS shows that it is transmitting but YouTube has not made the broadcast live, check the scheduled broadcast and Auto-start state. These observations distinguish a launch problem from a broadcast-state problem.
Repeat the test after changing the OBS profile, scene collection, stream key, task or scheduled broadcast. A shortcut can continue to launch OBS while the selected profile has changed, and a scheduled event can have different settings from the one you tested. Write down the account used, the launch route, the relevant OBS profile and the YouTube broadcast so another person can perform the same check.
For a channel that carries recorded material, also check what appears at the start of the file and whether playback behaves as intended after the OBS launch. Guides to adding background music to a recorded lecture stream and reusing a YouTube stream key for a continuous channel cover adjacent parts of a continuous-stream workflow, but they do not remove the need to verify this specific Windows and Studio sequence.
Check what happens after reboot or interruption
A sign-in test is not a reboot test. Restart Windows, then observe what actually happens from power-on through sign-in, OBS launch, encoder connection and YouTube broadcast state. If your PC normally waits at a sign-in screen, include that pause in the test. If it restarts into an account automatically, check that this is the account and behaviour you deliberately intended.
Also test with the network equipment in its ordinary state. After a power interruption, the PC can become ready before a router or other network equipment has restored internet access. An early OBS connection attempt may fail in that circumstance. A delay or a later manual restart may be a practical response, but neither is a universal fix: your equipment, Windows settings and connection determine what happens.
Test interruptions separately instead of treating “recovery” as a single feature. A Windows update and restart, a brief internet loss, a router reboot, an OBS crash and a household power cut are different events. After each one, check whether Windows starts, whether the correct user signs in, whether OBS launches, whether it reconnects, and whether YouTube shows the intended broadcast live. Do not assume that success in one case proves the others.
If you need a channel to continue while the computer is switched off, or to avoid having a local PC and home connection as dependencies, using an uploaded-file workflow can remove that specific burden. StreamNeo is for turning an uploaded video into a 24/7 YouTube live stream without leaving your own computer on; it does not change YouTube’s controls or make every channel configuration immune to interruption. If you are comparing approaches to scheduling stream start and stop times, keep the same distinction in mind: service choice and YouTube broadcast state still need to be understood separately.
Troubleshoot launch versus going live
When the expected result does not happen, identify the last stage that worked. Did Windows sign in? Did OBS open? Did the right scene appear? Did OBS begin streaming? Did YouTube show the correct scheduled broadcast live? This sequence makes troubleshooting less speculative than changing several settings at once.
| What you observe | First checks |
|---|---|
| Windows signs in, but OBS does not open | Confirm the shortcut is in the signed-in user’s Startup folder, or that the task trigger and account match the intended sign-in |
| OBS opens, but the expected scene is absent | Check the selected profile and scene collection, and test them manually |
| OBS opens, but does not begin streaming | Check the target or task argument for --startstreaming, then verify the encoder connection and stream key in OBS |
| OBS reports a connection issue after reboot | Confirm internet access is ready; test again after network equipment is online |
| OBS sends video, but the scheduled broadcast is not live | Check the specific YouTube broadcast’s Auto-start setting and whether Studio requires a manual Go Live action |
| YouTube is live, but the wrong content appears | Check the OBS scene, media source, audio and selected broadcast before leaving the stream unattended |
Change one relevant item and repeat the same test. For example, if OBS opens but is not streaming, changing YouTube Auto-start will not correct a missing --startstreaming argument. If OBS is sending video but the scheduled broadcast remains waiting, reinstalling OBS is unlikely to address the separate YouTube setting. Keep a brief record of the result so you do not repeat a change that has already failed.
If you cannot tell whether video is reaching YouTube, compare OBS’s connection status with Studio’s preview or broadcast state. Do not share a screenshot that exposes your stream key. When a restart or network interruption remains unreliable, the honest conclusion may be that this PC-based arrangement needs supervision or further testing, not that one more setting guarantees recovery.

FAQ
Does --startstreaming make my scheduled YouTube broadcast live?
It tells OBS to start streaming when OBS launches. For a scheduled broadcast, YouTube’s Auto-start setting is a separate control that affects whether the broadcast goes live as OBS sends video. Confirm the state in Studio rather than assuming the launch argument handles both steps.
Will this start OBS if Windows restarts while nobody is there?
A Startup-folder shortcut runs at that user’s sign-in, so reaching the sign-in screen alone may not start it. Task Scheduler offers different configuration choices, but choose and test the trigger that matches your account and unattended-login requirements. These settings do not turn the PC on after a power failure.
Does automatic launch recover from every internet or power interruption?
No. OBS may launch before networking is ready, a connection may fail, or YouTube may need a separate action. Test the actual interruptions your setup is likely to face and plan for supervision or a recovery step where needed.
Should I test the setup after changing OBS or YouTube settings?
Yes. Changes to the selected profile, scene, key, task or scheduled broadcast can alter a different part of the sequence. Repeat a supervised sign-in and reboot test, then verify the content and broadcast state in YouTube Studio.
