A factory reset usually takes 30 minutes to two hours, depending on your drive size and Windows version

The time varies most by whether you have a solid-state drive (SSD) or a traditional hard disk drive (HDD). An SSD will finish in 30 to 45 minutes. An HDD takes 1.5 to 2 hours or longer. Windows 11 is slightly faster than Windows 10. The process itself has no user input once you start it — the system runs through stages automatically, and you should not interrupt it.

The reset wipes your files, programs, and settings, then reinstalls Windows from scratch. During this time your screen will show progress bars and status messages. Your PC will restart several times. Once it finishes, you will see the Windows setup screen asking for your language and region, as if the machine were brand new.

Key Takeaways

  • SSDs complete a factory reset in 30 to 45 minutes; HDDs take 1.5 to 2 hours or more.
  • Do not turn off your PC or unplug it during the reset, even if the screen goes dark or seems stuck for several minutes.
  • The reset removes all your files and installed programs, so back up anything you want to keep before you start.
  • Your PC will restart multiple times and show different screens; this is normal and part of the process.

What happens during each stage of the reset

The reset begins when you choose Settings > System > Recovery > Reset this PC and select either "Keep my files" or "Remove everything." If you choose "Remove everything," the process takes the full time listed above. If you choose "Keep my files," it finishes faster — usually 20 to 30 minutes — because Windows does not have to erase as much data.

Once you confirm, Windows enters a preparation phase lasting 5 to 10 minutes. The system checks your drive, gathers files it needs, and prepares to restart. Your screen may show "Getting things ready" or a spinning circle. Then your PC restarts and enters the actual reset phase, which is the longest part. This is when Windows erases your drive and reinstalls itself. On an SSD this takes 20 to 30 minutes. On an HDD it can take 45 minutes to over an hour.

After the reset completes, Windows restarts again and boots into the setup screen. This final stage — where you choose your language, region, and sign-in method — takes another 5 to 10 minutes. Until you finish setup, your PC is not fully ready to use.

Why SSDs are significantly faster than HDDs

An SSD reads and writes data much faster than an HDD because it has no moving parts. An HDD uses a spinning disk and a mechanical arm to find and move data, which is slower. When Windows erases and rewrites an entire drive, the speed difference becomes obvious. An SSD can erase and rewrite gigabytes per second. An HDD manages only hundreds of megabytes per second.

If your PC has a 256 GB SSD, the reset finishes in roughly 30 minutes. If it has a 1 TB HDD, expect 90 minutes to 2 hours. Larger drives take longer because there is more data to erase. A 2 TB HDD can take 2.5 to 3 hours. The exact time also depends on your PC's processor and RAM, but the drive type is the biggest factor.

How to avoid common delays during a reset

The most common mistake is interrupting the reset. If your screen goes dark or shows no change for several minutes, do not turn off your PC. The system is working even if you cannot see progress. Unplugging or forcing a shutdown can corrupt Windows and force you to reinstall it manually, which takes much longer.

Another delay happens if your PC is low on storage space. Windows needs free space to write the new system files. If your drive is more than 90 percent full, the reset may fail or stall. Before you start, delete large files or programs you do not need, or move files to an external drive. Aim for at least 20 GB of free space.

Malware or corrupted system files can also slow the reset. If your PC is infected, the reset will remove the malware, but the process may take longer as Windows scans and cleans. If system files are damaged, Windows may need to repair them during the reset, adding 15 to 30 minutes.

What to do while your PC is resetting

Leave your PC plugged in and do not move it. If you are using a laptop, keep it plugged into power — a reset on battery power can fail if the battery drains. Do not close the lid or put the PC to sleep. The reset needs consistent power and an active screen.

You can step away from your PC while it resets. The process requires no input from you. Check back every 15 to 20 minutes to make sure the screen is still showing progress and the PC has not frozen. If the screen has not changed in 30 minutes and shows no progress bar, your PC may have stalled. In that case, wait another 10 minutes before deciding to restart it manually.

Differences between Windows 10 and Windows 11 reset times

Windows 11 resets slightly faster than Windows 10, usually by 5 to 10 minutes. Windows 11 has a more efficient reset process and smaller system files. On an SSD, Windows 11 may finish in 25 to 35 minutes, while Windows 10 takes 30 to 45 minutes. On an HDD, the difference is smaller — Windows 11 might save 10 minutes, but both versions still take over an hour.

The difference is noticeable but not dramatic. If you are upgrading from Windows 10 to Windows 11, the reset time is not a major factor in your decision. The bigger difference is in how the systems handle large files and background tasks, which does not affect reset speed.

What to expect after the reset finishes

Once the reset completes, your PC boots into the Windows setup screen. You will see options for language, region, and keyboard layout. Then you will sign in with a Microsoft account or create a local account. This setup takes 5 to 10 minutes. After you finish, your PC is ready to use, but it may take another few minutes to fully load the desktop and install drivers.

Your PC will be slower for the first 10 to 15 minutes after setup because Windows is indexing your drive and running background tasks. This is normal. Once indexing finishes, performance returns to normal. You can use your PC during this time, but it may feel sluggish.

Frequently Asked Questions

Can I use my PC while it is resetting?

No. Do not try to use your PC, open programs, or access files during a reset. The system is rewriting your entire drive and needs full control. Using your PC during a reset can corrupt Windows and force you to start over.

What if my reset takes longer than two hours?

If your reset is still running after two hours on an HDD or one hour on an SSD, something may have gone wrong. Wait another 30 minutes before deciding to stop it. If the screen has not changed and shows no progress bar, your PC may have frozen. You can force a restart by holding the power button for 10 seconds, then try the reset again.

Will a factory reset fix a slow PC?

A factory reset removes programs, files, and settings that may be slowing your PC, so it often does improve speed. However, if your PC is slow because of old hardware — like a full HDD or low RAM — a reset will not fix that. A reset is most helpful if you have installed many programs or if malware is slowing your system.

Do I need to back up my files before resetting?

Yes, if you choose "Remove everything," the reset deletes all your files. Back up anything you want to keep to an external drive or cloud storage before you start. If you choose "Keep my files," Windows preserves your documents and photos, but removes all programs and settings.

Why is my reset stuck on a black screen?

A black screen during reset is usually normal — Windows is working in the background. Wait at least 30 minutes before assuming it is stuck. If the screen has not changed in 45 minutes and there is no progress bar, your PC may have frozen. Force a restart and try again.
