How to Reset or Reinstall Windows 11 in 2026

At some point, almost every Windows 11 machine needs a reset. Maybe the system is sluggish after years of accumulated apps. Maybe a botched update broke something that no amount of troubleshooting will fix. Maybe you are selling the laptop and need to wipe it clean. Whatever the reason, Windows 11 gives you several reset paths — and choosing the wrong one wastes hours or loses data you did not mean to delete.

This guide walks through every option in 2026, what each one actually does, and how to pick the right one for your situation. It also covers what to do before you reset and the first things to set up once Windows is back.

Before you reset: a five-minute checklist

Skipping this checklist is where people lose things they wanted to keep. Go through it before touching anything.

• Back up personal files. Even "Keep my files" can fail if the drive has bad sectors. Copy your Documents, Desktop, Downloads, and Pictures folders to an external drive or OneDrive before starting.
• Export browser bookmarks. Chrome, Edge, and Firefox all have export functions under their settings menus. Sync to a browser account is even easier — sign in after reinstall and everything is back.
• Note your installed apps. Windows cannot transfer installed applications — you will reinstall them from scratch. Write down your key apps or take a screenshot of Programs and Features in Control Panel.
• Save game saves and app data. Many games store saves in Documents or a cloud service. Check the specific folder before wiping. Apps like accounting software, password managers, and email clients may need manual export steps.
• Check your Windows edition. Open Settings → System → About and note whether you have Windows 11 Home or Pro. The reset will reinstall the same edition. If you upgraded from Home to Pro, the Pro licence is tied to your Microsoft account.
• Disconnect non-essential peripherals. Leave only mouse, keyboard, and monitor. External drives, docks, and USB hubs can sometimes interfere with the reset process.

One thing you do not need to note down is your product key. Windows 11 digital licences are stored server-side and reactivate automatically on the same hardware after reinstall, as long as the machine was already activated before the reset.

Option 1: Reset this PC — Keep my files (the most common choice)

This is the option most people need. It removes all installed apps and reverses system settings to their defaults, but leaves your personal files — documents, photos, music — exactly where they are. The Windows installation is rebuilt from scratch, which fixes most corruption, broken-update, and slowdown problems.

1. Open Settings (Win+I) and go to System → Recovery.
2. Under "Recovery options", click Reset PC.
3. Choose Keep my files.
4. Choose between Cloud download or Local reinstall. Cloud download fetches a fresh Windows image from Microsoft (~4–5 GB); Local reinstall uses the recovery files already on the drive. If the system is behaving strangely, pick Cloud download — it guarantees a clean image.
5. Review the list of apps that will be removed (Windows shows you this before confirming), then click Reset.

The PC reboots into the reset process and comes back 20–60 minutes later with a clean Windows installation. You will find a text file on the desktop listing all the apps that were removed, so you know what to reinstall.

When to use it: slowdowns after years of use; persistent app or system errors that troubleshooting has not fixed; preparing a hand-me-down PC for a family member while keeping the current user's files.

Option 2: Reset this PC — Remove everything (full wipe)

This option wipes the entire drive and reinstalls Windows fresh. Your files, apps, and settings are all gone. It is the right choice when you are selling or donating the PC, when you want to completely start over, or when a "Keep my files" reset did not fix the underlying problem.

1. Follow the same path: Settings → System → Recovery → Reset PC.
2. Choose Remove everything.
3. If you are keeping the PC, choose Local reinstall for speed. If you are handing the PC to someone else, choose Cloud download to ensure the cleanest possible image.
4. When prompted about drive cleaning, choose Remove files and clean the drive if the PC is going to someone else. This overwrites the free space, making it much harder to recover files with data recovery tools. If you are keeping it yourself, "Just remove my files" is fast enough.
5. Confirm and let the process run. Expect 1–3 hours if doing a cloud download with drive cleaning.

After the wipe, Windows walks you through the same first-run setup (OOBE) you saw when the PC was new — region, account, privacy settings, and so on.

When to use it: selling or recycling the PC; serious malware infection you cannot clean; complete fresh start where you want no trace of the previous setup.

Option 3: Clean install from USB (the most thorough option)

A reset through Settings uses the recovery tools built into Windows — which means it relies on at least part of the existing installation being functional. A clean install from USB bypasses all of that. You boot from an external drive, wipe the partition, and install Windows from scratch. It is the most reliable way to get a truly clean system.

You will need a second PC (or your current one if it still boots) to create the USB, and a USB drive of 8 GB or more.

1. On any working Windows PC, go to microsoft.com/software-download/windows11 and download the Windows 11 Installation Assistant or the Media Creation Tool.
2. Run the Media Creation Tool and choose Create installation media (USB flash drive, DVD, or ISO file) for another PC.
3. Insert your USB drive, select it as the destination, and wait for the download and creation process to complete (15–30 minutes depending on your internet speed).
4. On the target PC, insert the USB, reboot, and press the BIOS/UEFI boot menu key (typically F12, F11, Esc, or F2 — varies by manufacturer) to select the USB drive as the boot device.
5. Choose your language, click Install now, skip the product key entry (Windows will reactivate automatically), choose Custom: Install Windows only (advanced), delete the existing Windows partition, and install onto the unallocated space.

The install process takes 15–30 minutes and drops you directly into the first-run setup. All previous data on the partition you deleted is gone.

When to use it: the PC will not boot at all and the built-in recovery does not work; you want the absolute cleanest possible result; you are replacing a drive and reinstalling.

Option 4: Startup Repair and system file fixes (before resetting)

If the problem is specific — Windows will not boot, a driver is causing crashes, Windows Update is stuck — it may be worth trying a targeted repair before committing to a full reset. Two tools worth running first:

• SFC (System File Checker): Run sfc /scannow in an elevated Command Prompt. It scans system files and replaces corrupted ones from a local cache. Takes about 10 minutes. Fixes a surprisingly wide range of problems.
• DISM: Run DISM /Online /Cleanup-Image /RestoreHealth in an elevated Command Prompt. It repairs the component store that SFC draws from. Requires internet access. Run this first if SFC finds errors it cannot fix.

If SFC and DISM do not resolve the problem, a reset is the next logical step. There is no shame in going straight to the reset — it is a designed-in recovery mechanism, not a last resort.

After the reset: first things to do

A freshly reset Windows 11 needs a bit of housekeeping before it is useful again. In order:

1. Run Windows Update immediately and completely. Expect multiple rounds of updates. Reboot when prompted and re-run Update until it shows "You're up to date." Security patches released after the image was created will not be present until you update.
2. Install your drivers. Windows usually handles graphics, audio, and network automatically, but for gaming GPUs (NVIDIA GeForce Experience / AMD Radeon Software) and any specialised hardware, download drivers directly from the manufacturer.
3. Configure privacy settings. The first-run setup asks some of these, but Settings → Privacy & security is worth a second pass. Diagnostic data, ad ID, location access, and app permissions all have defaults you may want to change.
4. Set up your productivity stack. Reinstall your core apps — browser, password manager, communication tools. Restore your backed-up browser bookmarks. Sign into services.
5. Set up a desktop that actually works for you. A blank desktop is a good excuse to build a better setup. The productivity dashboard guide covers adding always-visible calendar, task, and system stat widgets so you do not spend the next year staring at nothing but a wallpaper.

If performance is part of why you reset, the Windows 11 speed-up guide walks through power plans, startup programs, and visual effects — changes that make a measurable difference without reinstalling anything. Apply them to the fresh install before adding apps and the results will be more noticeable.

For those who work from home, the WFH setup guide covers virtual desktops, focus sessions, and the widget layer that makes a desk PC useful at a glance. It pairs well with a fresh install.

Which option is right for you?

• PC is slow or misbehaving but your files are fine: Reset → Keep my files → Local reinstall.
• PC has serious issues and you want the cleanest image: Reset → Keep my files → Cloud download.
• Selling or donating the PC: Reset → Remove everything → Cloud download → Remove files and clean the drive.
• PC will not boot at all: Create a USB on another machine, boot from it, clean install.
• Problem might be fixable without a reset: Run SFC and DISM first, then decide.

The "Keep my files" cloud-download reset covers the majority of cases where people are resetting a PC they plan to keep using. It takes under an hour on most modern machines and fixes nearly every software-level problem without any data loss.

If you are setting up a secure environment after the reset — encrypting files, setting strong authentication, or locking down folder access — the password-protect folder guide covers EFS, VeraCrypt, and 7-Zip methods that work well on a clean Windows install.

FAQ

Will resetting Windows 11 remove my personal files?

It depends which option you pick. "Keep my files" removes apps and settings but leaves your documents, photos, and other personal files in place. "Remove everything" wipes the drive entirely — that option is meant for when you are selling or recycling the PC. Before doing either, back up anything important to an external drive or cloud storage, regardless of which option you choose.

Do I need a Windows 11 product key to reinstall?

No — not in most cases. Windows 11 licences on retail and OEM machines are tied to the motherboard via a digital entitlement stored in Microsoft's servers. When you reinstall, Windows connects to Microsoft after setup and reactivates automatically, as long as you are reinstalling the same edition (Home or Pro) on the same machine. If you are moving a retail licence to a new PC, you need to deactivate on the old machine first.

How long does a Windows 11 reset take?

"Keep my files" with the local reinstall option typically takes 20–40 minutes on a mid-range SSD. "Remove everything" with cloud download can take 1–3 hours depending on your internet connection speed, because it downloads a fresh 4–5 GB Windows image. On an older spinning hard drive, add roughly 50 percent to those estimates.

What is the difference between "Local reinstall" and "Cloud download"?

Local reinstall rebuilds Windows using the recovery files already on your drive — faster, but those files may be corrupted if the system is seriously broken. Cloud download fetches a fresh Windows image from Microsoft's servers — takes longer but is guaranteed to use a clean, unmodified copy. If you are resetting because the OS is behaving strangely, cloud download is the safer pick.

Can I reset Windows 11 if the PC will not boot?

Yes. Boot the PC from a Windows 11 installation USB, choose "Repair your computer" instead of Install, then navigate to Troubleshoot → Reset this PC. Alternatively, some PCs can reach the Recovery Environment by pressing F11 or another OEM-assigned key at startup. If neither works, you will need to create a bootable USB on another machine using Microsoft's Media Creation Tool.

Will a reset fix a Windows Update stuck at 0%?

Usually yes — a "Keep my files" reset replaces system files and resets Windows Update components. If the stuck update is caused by a corrupted component store or broken service registration, a reset is the most reliable fix without doing a full clean install. Run the Windows Update Troubleshooter first; if it cannot fix the problem automatically, a reset is the next sensible step.
