Windows can open OBS when you sign in, and OBS can be configured to begin sending a stream to YouTube. Those are separate actions: neither one selects the right YouTube broadcast nor makes a playlist play and appear in the stream.
Treat the setup as a chain to configure and rehearse: Windows sign-in, OBS launch and output, YouTube broadcast settings, then playlist playback and capture. A reliable result depends on each link working on your channel and computer, so do not rely on startup settings until you have tested the complete sequence.
Separate Windows launch from stream startup
There are several meanings of “start automatically” in this setup. Windows can open an application after a user signs in. OBS can start its streaming output when it launches. YouTube Studio controls the broadcast that receives that output and whether it is public or waiting for an action. The playlist itself must also be playing, and OBS must capture its picture and sound.
Configuring one step does not configure the others. Putting OBS in the Windows Startup folder does not tell it to stream. Adding OBS’s streaming launch parameter does not activate live streaming on a YouTube channel, choose a scheduled broadcast, or start a playlist. A successful test of the OBS window opening is therefore not proof that viewers can see and hear the intended programme.
For example, a church might want a recorded Bible study playlist to repeat overnight. Windows could sign in and open OBS while the playlist is paused. Or OBS might send data while YouTube Studio is set to a different scheduled broadcast. Write down what you expect to happen at each stage, then verify each item rather than treating “the stream started” as a single result. For a recording-based church channel, the practical considerations in running a 24/7 stream of Bible study recordings are relevant too.
This distinction matters most after a restart, power interruption or Windows update. You may return to an open desktop with OBS running but no active broadcast, or to a broadcast receiving a frozen scene. The point of the checklist below is to find those gaps while you can still observe the computer and Studio.
Add OBS to Windows sign-in startup
On Windows, the usual way to launch an app at sign-in is to put a shortcut to it in the user’s Startup folder. This is a Windows sign-in action, not a setting inside OBS. It also means the app starts only after the relevant Windows account signs in; it does not mean the PC has booted into a ready-to-stream session without any other configuration.
First, install OBS and open it normally. Confirm that the profile, scenes and sources you intend to use are present. Then create a shortcut to OBS Studio, rather than moving or modifying the application itself. Open the Startup folder for the Windows account that will run the stream and place the shortcut there. If more than one account exists on the PC, check that you have used the account whose OBS configuration and YouTube credentials are prepared.
The exact path to OBS depends on where it was installed. If you are unsure which executable the shortcut should open, find the OBS shortcut you already use, inspect its properties, and use that target as the basis for the startup shortcut. Avoid copying an example path from another computer: a different install location would leave Windows trying to open a file that is not there.
A sign-in startup entry is not the same as running OBS before anyone signs into Windows. If your operating arrangement requires a logged-in desktop, plan for that explicitly and test what happens after a restart. Also check that the computer is not set to sleep soon after sign-in; a running application cannot keep transmitting if Windows suspends the machine. The steps for preventing sleep-related stream disconnects cover that separate failure point.
Add --startstreaming to the OBS shortcut if needed
OBS documents --startstreaming as a launch parameter that starts streaming output when OBS opens. To use it, edit the shortcut’s Target field: leave the existing executable path intact and add a space followed by --startstreaming after the closing quotation mark, if the path is quoted. Do not put the parameter inside the quoted path.
The OBS Project’s launch parameters documentation explains the option and the shortcut configuration. A target might look like this in shape, with the path adjusted to your installation: "C:\Program Files\obs-studio\bin\64bit\obs64.exe" --startstreaming. Treat that as an example, not a universal install location.
For a scheduled task or another automated launch method, OBS says to set the shortcut’s “Start in” working directory to the folder containing obs64.exe. This avoids relying on a working directory that may differ when Windows starts the application outside your usual desktop routine. Follow the OBS documentation for the launch method you actually use.
Use this parameter only after you have confirmed that OBS is configured to connect to the intended YouTube channel and that the output is safe to start. It is not a YouTube broadcast selector. It cannot tell whether the channel has enabled live streaming, whether Studio is waiting for confirmation, or whether the correct scheduled broadcast is selected. If you want OBS to open without sending data while you inspect the scene, do not add the parameter until you have completed that check.
OBS’s Quick Start Guide recommends its Auto-Configuration Wizard as a way to choose initial settings based on computer resources and network conditions. Use it as a starting point rather than assuming a particular resolution or bitrate suits every connection. A spare PC or a connection with limited capacity may need a different compromise; the considerations in preparing videos for a 24/7 stream from a spare PC can help you decide what to test.
Confirm YouTube live streaming and broadcast settings
OBS cannot send a live stream to a channel that is not ready to accept one. YouTube’s encoder setup guidance says live streaming must be enabled for the channel. Enabling it for the first time may take up to 24 hours, so do not leave activation until just before an intended launch.
Connect OBS to YouTube in one of the ways available in your installed version. If a YouTube service integration is offered, follow its sign-in and authorisation steps. Otherwise, YouTube’s encoder flow provides a stream URL and key to enter in OBS. The integration may simplify setup; manual URL and key entry is a straightforward alternative when that integration is unavailable. Keep the key private: anyone with access to it could attempt to send a stream to your channel.
Before enabling --startstreaming, open YouTube Studio and check which broadcast is meant to receive the encoder output. A scheduled live event and a general encoder session may not behave the same way. Depending on the current controls and settings on your channel, YouTube may start publishing automatically or wait for you to confirm the broadcast in Studio. Do not assume that labels or behaviour described in an older guide match your present account. Verify the actual controls in Studio and rehearse the state you will use.
Make the first check with a controlled test, such as a private or unlisted broadcast if those options fit your purpose. Confirm the title, visibility and destination before you send output. Then observe whether Studio shows incoming encoder data, whether it begins the broadcast, and what a viewer would see. This check is about the channel’s actual configuration, not just the presence of a green indicator in OBS.
Make sure the playlist is playing and captured
Open the intended YouTube playlist and start playback. On desktop YouTube, the playlist control box includes a Loop control, documented in YouTube’s playlist help. Confirm that looping is on and that the next item begins. A playlist page left open at its first video is not enough if playback is paused or the list stops at the end.
OBS also needs a source that actually captures the playing content. Depending on the arrangement, that could be a captured window or display, with an audio source that receives the computer’s playback. The correct source and audio routing depend on the Windows version, OBS configuration and how the browser is run. Check that the preview shows the video and that the audio meter responds when the video has sound; then listen to the resulting stream from another device. A visible preview alone does not establish that viewers receive audio.
Avoid assuming that embedding a YouTube playlist in a browser source is automatically a dependable or approved unattended playback method. An embed or autoplay setting in a page does not by itself establish that the browser will continue advancing, that audio will be captured, or that the content is suitable for retransmission. Test the exact source arrangement you plan to use, including what happens when a video ends and the next one begins.
Rights are a separate check from technical capture. YouTube says it scans live streams for third-party content; a match can interrupt or terminate a stream. Its copyright guidance for live streams also notes that licensing alone may not prevent interruptions if the rights owner has not allowlisted the channel through Content ID. Check that you have the necessary rights for live use and any archive created from the stream. For more on the channel risk, see what can happen when copyrighted videos are streamed continuously.
Test the full chain before relying on it
Do a complete rehearsal before leaving the arrangement unattended. Start with the machine in the state it will actually be in, then sign out and back in or restart it if that is part of your normal recovery plan. Watch whether Windows opens the intended OBS installation and profile. Confirm the expected scene and sources load, rather than assuming that the last-used scene is the right one.
If --startstreaming is enabled, observe whether OBS begins sending output. In Studio, check that the correct channel and broadcast receive it, and determine whether YouTube has published or is waiting for a confirmation. If you have not enabled the launch parameter, check that you can start output manually and complete the same broadcast steps. Either way, distinguish “OBS is open”, “encoder data is arriving” and “the broadcast is public”.
Then verify the playlist end to end. Look for movement in the OBS preview, listen to the captured sound, and check from a separate device that the YouTube viewer receives both. Let the playlist advance to another item and confirm that it loops as expected. A short test of one video does not tell you what happens at a playlist boundary, after a browser notification, or when the audio source changes.
Write down the result of each check and any action that still requires you. If a Studio confirmation is needed after sign-in, that is a manual step in your current setup, not something Windows Startup has solved. If the stream must recover after a network failure or computer restart, test those situations separately and keep a recovery plan. A checklist makes the limits visible; it does not turn a Windows PC into a guaranteed unattended publishing system.
For a channel whose main requirement is to keep a prepared file broadcasting without a home computer left running, StreamNeo removes the particular burden of keeping that PC open: you upload a video and connect the YouTube stream key, while the file runs as a continuous stream. That is a different workflow from having OBS capture a live-playing YouTube playlist, so check that it suits your content and channel before choosing it.

FAQ
Does putting OBS in the Startup folder start my YouTube stream?
No. It opens OBS after the relevant Windows user signs in. OBS output, YouTube broadcast state and playlist playback are separate steps that need their own configuration and testing.
What does --startstreaming do?
It tells OBS to start its streaming output when OBS launches. It does not enable live streaming on YouTube, select a broadcast, or confirm that the playlist is playing and being captured.
Will the playlist keep playing after Windows signs in?
Only if playback is running, looping is configured as intended, and OBS is capturing both picture and audio. Test the actual browser, source and audio setup through a playlist transition before relying on it.
Can I leave this setup unattended after one successful start?
A successful test is useful but does not guarantee future publishing or uninterrupted streaming. Check the current Studio controls, computer sleep and restart behaviour, content rights, and any steps that still require you to act.
