Windows Recovery Environment (WinRE) is Windows’ built-in troubleshooting workspace for PCs that will not start, repeatedly restart, or became unstable after an update, driver, or software change. Enter it through Settings, Shift + Restart, Automatic Repair, a recovery USB, or Windows installation media. Use the least destructive option first: Startup Repair, update removal, System Restore, Safe Mode, offline repairs, and only then Reset or reinstall.
This guide covers Windows 11 first and Windows 10 separately where the paths differ. Microsoft ended normal free support for Windows 10 on October 14, 2025, although its WinRE tools can still be used on an existing installation. See Microsoft’s Windows Recovery Environment documentation.
Before you start
- Connect AC power. Disconnect unnecessary USB drives, docks, printers, and other accessories.
- If Windows still opens, copy important files to another drive or cloud storage first.
- Find the device’s BitLocker recovery key before using advanced tools. A normal Windows sign-in password is not that key.
- Do not repeatedly cut power during normal operation. Forced shutdowns are reserved for a boot sequence that is already failing.
- If the drive is clicking, disappearing, overheating, or reporting severe errors, prioritize data preservation over repeated repairs.
WinRE is associated with a Windows installation; it is not a separate operating system you normally install. Safe Mode is a limited Windows startup mode launched from WinRE’s Startup Settings. A recovery drive is bootable USB recovery media. Installation media can either open recovery tools or start a fresh installation. System Restore and Reset this PC are individual tools inside WinRE, not names for WinRE itself.
How to open Windows Recovery Environment
Windows 11 Settings
- Open Start > Settings.
- Select System > Recovery.
- Beside Advanced startup, select Restart now, then confirm.
Windows 10 Settings
- Open Start > Settings.
- Select Update & Security > Recovery.
- Under Advanced startup, select Restart now.
Shift + Restart
From the desktop or sign-in screen, select the Power icon, hold Shift, and select Restart. Keep holding Shift until the recovery menu appears.

With administrative access, shutdown /r /o /f /t 0 normally requests an immediate restart into advanced startup. The graphical paths above are the primary Microsoft-documented instructions.
When Windows will not boot
Windows may enter Automatic Repair after repeated failed starts. To force that process only when startup is already failing:
- Turn on the PC.
- When the Windows or manufacturer logo appears, hold the power button until it shuts down.
- Repeat once more.
- Start the PC a third time and wait for Automatic Repair, then choose Advanced options.
If this does not work, boot from a previously created recovery USB. The manufacturer’s boot-menu key varies by model.
Windows installation USB
- On another working PC, create Windows installation media using Microsoft’s official process.
- Insert it into the failed PC and boot from the USB (change the boot menu or UEFI boot order if necessary).
- At Windows Setup, choose language and keyboard options and select Next.
- Select Repair my PC, not the installation option.
Booting installation media and selecting Repair my PC does not reinstall Windows; reinstallation starts only when you choose the installation workflow. Details and the recovery-media route are in Microsoft’s WinRE instructions.
What the WinRE menu means
The wording can vary by Windows build, manufacturer image, and whether you booted internal recovery or external media.
- Continue: Leave WinRE and attempt normal Windows startup.
- Use a device: Boot from USB, DVD, network media, or another listed device.
- Troubleshoot: Open Reset this PC or Advanced options.
- Turn off your PC: Shut down without attempting repair.
Under Troubleshoot > Advanced options you may see Startup Repair, Startup Settings, Command Prompt, Uninstall Updates, System Restore, Point-in-time restore, UEFI Firmware Settings, and System Image Recovery. Not every PC exposes every item.
Choose the least destructive tool first
| Symptom or change | First option | Next option | Main limitation |
|---|---|---|---|
| Windows will not start or loops | Startup Repair | System Restore | Does not repair failing hardware or all corruption |
| Failure followed a Windows update | Uninstall latest quality update | Uninstall latest feature update or System Restore | Rollback availability varies |
| Failure followed a driver or app | System Restore | Safe Mode | A restore point may not exist |
| Windows starts only in a loop | Startup Settings > Safe Mode | Remove the suspected driver or app | Safe Mode reduces drivers and services |
| Possible system-file corruption | Command Prompt with CHKDSK/SFC | Offline DISM, then Reset or reinstall | Wrong drive letter can target the wrong installation |
| Windows is badly damaged but files matter | Reset this PC > Keep my files | Back up and clean-install | Apps and settings are removed |
| Drive is absent in UEFI | Hardware diagnosis | Drive replacement or recovery service | Software repair cannot fix a missing drive |
This ordering follows Microsoft’s recovery-options guidance.
Startup Repair
Choose Troubleshoot > Advanced options > Startup Repair when Windows does not start, repeatedly restarts, hangs while loading, or displays a boot error. It automatically diagnoses and attempts to repair common startup problems and may restart the PC.
Startup Repair is not a general repair for a dead SSD, defective memory, malware, severe disk damage, or every user-profile problem. If it reports that it could not repair the PC, continue with the option that matches the cause rather than assuming all recovery tools are exhausted.
Uninstall a bad update
Open Troubleshoot > Advanced options > Uninstall Updates when the failure began immediately after Windows Update.
- Uninstall latest quality update: Usually the first choice for a recent monthly or cumulative update.
- Uninstall latest feature update: Use for a larger Windows version upgrade when its rollback window remains available.
Windows may require an administrator account or BitLocker recovery key. Removing an update may not reverse every related driver or configuration change.
System Restore
Choose Troubleshoot > Advanced options > System Restore when Windows worked before a driver, application, or system-setting change and a restore point exists. System Restore rolls back system files, installed programs, drivers, and settings associated with the selected point. It is designed not to delete ordinary personal documents, but it is not a backup of photos or other files.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsIf no usable restore point was created or system protection was disabled, this option cannot help. Microsoft explains using System Restore from WinRE in its recovery-options guide.
Point-in-time restore
Some current Windows builds list Point-in-time restore separately. Where available, it can roll back a broader system state, including apps, settings, and personal files, to a recent automatic restore point. Availability and behavior depend on build and configuration; use ordinary System Restore when this item is absent.
Startup Settings and Safe Mode
Go to Troubleshoot > Advanced options > Startup Settings > Restart. After reboot, choose the number shown on your screen. Useful entries include:

- Enable Safe Mode: Minimal drivers and services.
- Enable Safe Mode with Networking: Adds networking components; it is not always necessary and exposes more services.
- Enable Safe Mode with Command Prompt: Starts a command-line-oriented minimal session.
- Enable low-resolution video: Useful for display-driver diagnosis.
- Disable automatic restart on system failure: Keeps a blue-screen error visible.
- Disable Driver Signature Enforcement and Disable early launch anti-malware protection: Temporary diagnostic choices that reduce protection and should not be left as a normal configuration.
Safe Mode helps determine whether a third-party driver, startup program, or security product is involved; it does not prove that hardware is healthy. Microsoft’s current option list is at Windows Startup Settings.

If Safe Mode keeps loading, press Win + R, enter msconfig, open the Boot tab, clear Safe boot, select Apply, and restart.
Use Command Prompt safely
WinRE assigns drive letters independently of normal Windows. Your Windows folder may be on D: or another letter, not C:. In Command Prompt, run:
BCDEditIn the Windows Boot Loader section, note the value beside osdevice. The examples below use D:; substitute the letter you found.
Check and repair the file system
CHKDSK /f D:CHKDSK can take a long time on a large or damaged disk. Do not interrupt it unless the machine is clearly frozen for an unusually long period.

SFC /scannow /offbootdir=D: /offwindir=D:windowsRepair the offline Windows image
DISM /image:D: /cleanup-image /restorehealthMicrosoft documents this sequence in a Windows Server troubleshooting procedure; on consumer Windows it is an advanced technique, not a guaranteed fix. If DISM reports that it repaired the image, run the offline SFC command again. See the exact sequence at Microsoft Learn.
Do not treat bootrec, bcdboot, diskpart clean, registry edits, offline malware-removal commands, or commands that delete pending updates as universal fixes. UEFI/GPT, legacy BIOS/MBR, encrypted volumes, and damaged EFI partitions require different procedures; selecting the wrong disk or partition can make the PC less bootable or destroy data.
Reset Windows from WinRE
Use Troubleshoot > Reset this PC only after repair tools fail and important files are backed up.
| Choice | What it does | Key trade-off |
|---|---|---|
| Keep my files | Reinstalls Windows while intending to retain personal files | Removes desktop apps and resets settings; it is not a backup |
| Remove everything | Removes personal files, apps, and settings | Use only after confirming you have the data you need |
| Cloud download | Downloads a fresh Windows image | Needs a suitable connection and can take longer; WinRE networking varies by build |
| Local reinstall | Uses recovery files already on the PC | Faster and offline, but may fail if those files are corrupted |
| Clean data | Makes deleted data harder to recover for a sale, donation, or recycling | Microsoft says it is not government- or industry-certified erasure |
The screen can remain black for an extended period, occasionally more than 15 minutes. Do not force a shutdown merely because the display is blank. Reset cannot cure a failing SSD, defective RAM, overheating, bad power supply, or another hardware fault. Microsoft’s full reset behavior is documented at Reset your PC.

UEFI Firmware Settings
Choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart to enter the motherboard or device firmware. You can inspect boot order, Secure Boot, and storage configuration, but change settings only when you know what they control; an incorrect change can stop a healthy Windows installation from booting.
System Image Recovery
This option restores an entire compatible system-image backup. It is not selective file recovery and may overwrite newer files, applications, and system changes. It is useful only when a usable image and any required storage or recovery hardware are available.
When BitLocker asks for a recovery key
BitLocker may require a recovery credential before WinRE can unlock the Windows volume or run certain tools. The recovery password is usually a 48-digit number, not your normal sign-in password. Depending on how the device is managed, it may be stored in a Microsoft account, Microsoft Entra ID, Active Directory, a file, or a printed record.
A manually started WinRE session and some Reset operations can trigger this prompt. Do not attempt to bypass BitLocker: without the recovery credential, encrypted data may remain inaccessible. Microsoft’s BitLocker recovery overview also documents Win + Ctrl + Enter to activate Narrator on the recovery screen.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
When WinRE does not fix the PC
- Try Settings or Shift + Restart if Windows can still reach them.
- Try Automatic Repair, then a recovery USB.
- Boot Windows installation media and choose Repair my PC.
- Check UEFI to see whether the internal drive is detected. If it is missing, suspect the drive, cabling, controller, power, or motherboard rather than Windows.
- If tools repeatedly fail, back up data before reinstalling or replacing the drive.
- If the drive is failing and the data is important, stop repair attempts and consult a professional data-recovery service.
Installation media may be necessary when Startup Repair or System Restore cannot help. Networking inside WinRE is not guaranteed: Microsoft currently identifies networking features as available only within the Windows Insider Program, while some recovery features may require an internet connection. Do not assume Wi-Fi, browsing, or downloads will work in every session.
When to stop and choose a reinstall or repair service
- The drive is absent from UEFI, repeatedly disconnects, or produces mechanical noises.
- CHKDSK reports escalating unreadable sectors or the PC becomes less stable during every attempt.
- BitLocker data is important but the recovery key cannot be found.
- There is suspected malware and you cannot safely preserve a trusted backup.
- Repeated resets and reinstalls fail, indicating a likely hardware or firmware problem.
In these cases, preserving data and diagnosing hardware is safer than running more destructive commands. Microsoft’s recovery-options guidance describes installation media as the fallback when built-in recovery does not work.
