Windows launches automatically when you turn on a new PC

When you power on a brand-new computer, Windows starts by itself. You do not need to do anything special to launch it — just press the power button on the front or back of the machine, wait 30 to 60 seconds, and the Windows startup screen appears. The first time you turn it on, you will see a setup wizard that walks you through creating a user account, connecting to the internet, and choosing basic settings.

If Windows does not appear after you press the power button, check that the power cable is plugged in firmly at both the wall outlet and the back of the PC. Some computers have a separate power switch on the back of the power supply unit (a large box inside the case); flip that switch to the "on" position first, then press the front power button.

Key Takeaways

  • Press the power button on the front or back of your PC and wait 30 to 60 seconds for Windows to start; you do not need to do anything else.
  • During first startup, Windows will ask you to create a user account, connect to Wi-Fi or ethernet, and choose privacy settings — take your time and read each screen.
  • If the screen stays black after pressing power, check that the power cable is connected and the power supply switch (if your PC has one) is turned on.
  • Windows updates automatically during the first startup, which can take 10 to 20 minutes; do not turn off the PC during this time.
  • Once setup is complete, you can launch Windows again anytime by pressing the power button; it will resume to your desktop in 10 to 30 seconds.

What happens during the first startup

The first time you turn on your new PC, Windows runs a setup process called Out-of-Box Experience (OOBE). This wizard appears on your screen and asks you a series of questions. You will be asked to select your language, region, and keyboard layout. Then you will create a user account by typing a username and password — this is the account you will use to log in every time you start the PC.

After you create your account, Windows asks whether you want to connect to the internet. If you have a Wi-Fi network nearby, select it from the list and enter the password. If you are using an ethernet cable (a wired connection plugged into the back of your PC), Windows usually detects it automatically. Internet connection is not required to finish setup, but you will need it eventually to read updates and use most programs.

Next, Windows asks about privacy settings. You can choose whether to allow Microsoft to collect data about how you use your PC, whether to use your location, and whether to turn on features like Cortana (a voice assistant). These settings can be changed later, so do not worry about getting them perfect now.

How long the first startup takes

The entire first-time setup usually takes 15 to 30 minutes, depending on your internet speed and how many updates Windows needs to read. During this time, your PC may restart several times — this is normal and expected. Do not turn off the PC or unplug it while setup is running, because interrupting the process can cause problems.

After you finish answering the setup questions, Windows downloads and installs updates in the background. This can take another 10 to 20 minutes. You will see a progress bar or a spinning circle on your screen. Once all updates are installed, your PC may restart one more time, and then you will see your desktop — the main screen with icons and a taskbar at the bottom.

Starting Windows on days after the first startup

Once setup is complete, starting Windows is straightforward. Press the power button on your PC, and it will boot up in 10 to 30 seconds. You will see a login screen asking for your username and password (or a PIN if you set one up). Type your password and press Enter, and Windows will load your desktop.

If your PC is already on but the screen is dark or locked, move your mouse or press any key to wake it up. The login screen will appear, and you can enter your password again. If you want to shut down Windows completely, click the Start button (the Windows logo in the bottom left corner), select the power icon, and choose "Shut down."

Troubleshooting if Windows does not start

If you press the power button and nothing happens, first check the power cable. Make sure it is plugged into a working wall outlet — try plugging a lamp into the same outlet to confirm the outlet has power. Then check that the cable is connected firmly to the back of your PC. If your PC has a separate power supply switch (usually a black switch on the large box inside the case), make sure it is flipped to the "on" position.

If the PC powers on but the screen stays black, wait at least two minutes. Sometimes Windows is loading in the background and the display has not turned on yet. If the screen is still black after two minutes, try pressing the power button on your monitor (the screen itself) to make sure it is turned on. If you see a message like "No Signal" on the monitor, the video cable connecting the monitor to the PC may be loose — unplug it and plug it back in firmly.

If the PC makes beeping sounds when you press the power button, or if you see error messages, the hardware may need attention. Write down any error messages you see and contact the PC manufacturer's support line — they can walk you through the next steps.

Connecting peripherals before first startup

Before you turn on your new PC for the first time, you should connect your monitor (screen), keyboard, and mouse. Plug the monitor cable into the video port on the back of the PC — this is usually a port labeled HDMI, DisplayPort, or VGA. Plug the keyboard and mouse into the USB ports (rectangular slots) on the back or front of the PC. If your keyboard and mouse are wireless, insert batteries into them first, then turn them on.

You can also connect a printer, external hard drive, or other devices before startup, but they are not required to get Windows running. Windows will recognize most devices automatically once it starts up. If a device does not work right away, you may need to read a driver (a small program that tells Windows how to use that device), but you can do that after setup is complete.

Frequently Asked Questions

Do I need to install Windows myself on a new PC?

No. Windows comes pre-installed on most new PCs sold by manufacturers like Dell, HP, Lenovo, and ASUS. When you turn on the PC for the first time, Windows is already there — you just need to run the setup wizard. If you built your own PC from parts or bought a used PC without Windows, you would need to install it, but that is a different process.

What if I forget my password after the first startup?

You can reset your password on the login screen. Click "I forgot my password" and follow the prompts — Windows will ask you security questions or send a code to your email address. If you set up a PIN instead of a password, you can reset that the same way. Keep your password or PIN somewhere safe so you do not forget it again.

Can I skip parts of the Windows setup wizard?

You can skip some steps, but you cannot skip creating a user account — Windows requires at least one account to log in. You can skip connecting to Wi-Fi during setup and do it later, and you can skip most privacy settings and change them afterward. However, skipping internet connection means Windows cannot read updates right away, so you will need to connect eventually.

Why does Windows restart multiple times during first startup?

Windows restarts during setup to explore updates and complete installation steps. Each restart is part of the normal process. Do not turn off your PC during these restarts — let them finish on their own. If a restart takes longer than five minutes, the PC may be stuck, and you can press the power button to force a shutdown, then turn it back on.

Is it normal for the first startup to be slow?

Yes. The first startup is slower than normal because Windows is downloading and installing updates, checking hardware, and setting up your user account. After the first few startups, Windows will boot faster as updates finish installing. If your PC is still very slow after a week of use, you may have too many programs starting automatically — you can disable them in Settings.
