If your PC won’t finish a reset, the short answer is: the Windows recovery environment, system files, disk/partition layout, encryption, drivers, or a bad Windows image are usually to blame. This article explains why System Reset doesn’t work in Windows 10 and shows practical fixes you can follow step by step.
You’ll learn the most common causes, quick solutions, detailed commands and menus, and when to use alternative recovery options so you can get Windows back to a clean state.
Key Takeaway
The single most effective approach is to repair Windows’ recovery environment and system image first using SFC, DISM, and reagentc, check and repair the disk, disable encryption and third-party blockers, and—if needed—use a Windows 10 installation media to reset or reinstall Windows cleanly.

Detailed Fixes for “System Reset doesn’t work in Windows 10”
Below are the 12 reasons listed above, each with why it happens and detailed, step-by-step solutions.
1. Corrupt system files
Why it causes the problem:
- Reset relies on a healthy Windows image and system files; corruption prevents reset from copying or restoring required files.
How to fix:
- Open Command Prompt as administrator (Press Start, type cmd, right‑click Command Prompt → Run as administrator).
- Run: sfc /scannow
- Wait for completion. SFC will repair many file issues.
- If SFC reports corruption that it can’t fix, run:
- DISM /Online /Cleanup-Image /ScanHealth
- DISM /Online /Cleanup-Image /RestoreHealth
- Reboot and try Settings → Update & Security → Recovery → Reset this PC → Get started again.
Notes:
- DISM needs internet access to retrieve replacement files if local source is bad; use installation media if offline.
2. Broken Windows Recovery Environment (WinRE)
Why it causes the problem:
- The Reset process often invokes WinRE; if WinRE is disabled or its files are missing, reset may fail.
How to fix:
- Open Command Prompt (Admin).
- Check status: reagentc /info
- If Windows RE status: Disabled, run:
- Re-enable WinRE:
- reagentc /enable
- If WinRE path is missing or copies are corrupt, you can point to WinRE.wim:
- If you have install.wim or install.esd on installation media, extract or use media to repair WinRE, or use:
- Copy Winre.wim from installation media to C:\Windows\System32\Recovery (create folder if needed), then:
- reagentc /setreimage /path C:\Windows\System32\Recovery
- reagentc /enable
- Reboot and retry reset.
Tips:
- If reagentc errors, use Media Creation Tool to create a recovery USB and boot from it.
3. Insufficient disk space
Why it causes the problem:
- Reset (especially with “Keep my files” or system image rebuild) needs free space for temporary files and image extraction.
How to fix:
- Free space quickly: remove large files, uninstall programs (Settings → Apps), or move data to external storage.
- Use Disk Cleanup: Press Start, type Disk Cleanup, select C:, and choose Clean up system files.
- Ensure at least 20–30 GB free (more if you have many apps/files).
- Try reset again.
Notes:
- If disk is nearly full and you can’t free space, connect an external drive and move personal data temporarily.
4. Third‑party apps or antivirus blocking reset
Why it causes the problem:
- Security software, system utilities, or shell extensions can interfere with file replacement or WinRE.
How to fix:
- Uninstall third-party antivirus/security software via Settings → Apps (or vendor uninstallers).
- Boot to Safe Mode and attempt reset:
- Settings → Update & Security → Recovery → Advanced startup → Restart now → Troubleshoot → Advanced options → Startup Settings → Restart → press 4 for Safe Mode.
- If reset still fails, create Windows installation media on another PC and perform reset or clean install from USB.
Tip:
- Some AVs require special removal tools; check vendor support pages.
5. Pending or corrupted Windows Updates
Why it causes the problem:
- An interrupted or pending update can lock files and prevent reset from proceeding.
How to fix:
- Run Windows Update Troubleshooter:
- Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update.
- Reboot and install all updates: Settings → Update & Security → Windows Update → Check for updates.
- If updates are stuck, from admin Command Prompt:
- net stop wuauserv
- net stop bits
- Delete contents of C:\Windows\SoftwareDistribution\Download
- net start bits
- net start wuauserv
- Reboot and try reset.
Notes:
- For severely broken update components, use DISM commands listed earlier.
6. Corrupt user profile
Why it causes the problem:
- Reset from within a problem user account may fail if essential profile files are invalid.
How to fix:
- Create a new admin account:
- Settings → Accounts → Family & other users → Add someone else to this PC; create a local admin.
- Sign in to the new admin account and run the reset from Settings → Update & Security → Recovery.
- Alternatively, back up data and perform a clean install.
Tip:
- Backup Desktop, Documents, and AppData (if needed) before making changes.
7. BitLocker encryption enabled
Why it causes the problem:
- Reset may need to access or rewrite the system volume; encryption prevents that if not suspended or decrypted.
How to fix:
- Open Control Panel → System and Security → BitLocker Drive Encryption.
- For your system drive, choose Suspend protection or Turn off BitLocker (decryption may take time).
- Alternatively use admin command prompt:
- manage-bde -status
- manage-bde -protectors -disable C:
- Run reset again.
Notes:
- If you don’t have recovery keys, decrypting may be impossible—locate keys from your Microsoft account or backup.
8. UEFI/BIOS and boot mode conflicts
Why it causes the problem:
- If the disk was installed in Legacy (MBR) but BIOS set to UEFI, or if Secure Boot/CSM changes occurred, Reset may fail during boot or BCD repair.
How to fix:
- Enter BIOS/UEFI settings (restart, press F2/Del/F12 depending on vendor).
- Check boot mode: UEFI vs Legacy/CSM—set to the mode that matches your Windows installation.
- If bootloader is corrupt, use WinRE Command Prompt and run:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /scanos
- bootrec /rebuildbcd
- If bootrec /fixboot returns Access Denied, run:
- diskpart
- list disk
- select disk 0 (choose correct disk)
- list partition
- select partition X (EFI partition, typically ~100MB)
- assign letter=Z
- exit
- Then in elevated cmd: cd /d Z:\EFI\Microsoft\Boot\ and bootrec /fixboot. If needed rebuild BCD with bcdboot C:\Windows /l en-us /s Z: /f ALL
- Reboot and retry reset.
Warnings:
- Be careful with diskpart; selecting the wrong disk/partition can cause data loss.
9. Failing hard drive or SSD
Why it causes the problem:
- Physical drive errors prevent files from being read/written correctly, causing reset to stall or fail.
How to fix:
- Check disk health:
- In admin Command Prompt: chkdsk C: /f /r
- For SMART: wmic diskdrive get model,status,serialnumber (basic), or use vendor SSD tools (Samsung Magician, Western Digital Dashboard).
- If chkdsk reports extensive bad sectors or SMART indicates failure, back up data immediately and replace the drive.
- After drive replacement, perform reset or clean install from installation media.
Notes:
- chkdsk can take hours; run overnight if necessary.
10. Corrupt Windows image used for reset
Why it causes the problem:
- Reset may use the local image in C:\Windows\System32\Recovery\Customizations or installation media; if that image is corrupt, reset will fail.
How to fix:
- Repair the image with DISM using local source or online:
- DISM /Online /Cleanup-Image /RestoreHealth /Source:WIM:X:\sources\install.wim:1 /LimitAccess
- Replace X: with your USB drive letter.
- If repair fails, create a fresh Windows 10 USB using the Media Creation Tool on another PC and either use it to run an in-place repair or clean install.
- From the USB: boot, choose Repair your computer → Troubleshoot → Reset this PC or perform a clean install.
Tip:
- Using the matching Windows build (version) for source files avoids compatibility errors.
11. Network/cloud reset issues
Why it causes the problem:
- Cloud Reset needs a working internet connection and a viable Microsoft recovery image; network errors or blocked downloads stop the process.
How to fix:
- Try local reset first: Settings → Update & Security → Recovery → Reset this PC and choose Local reinstall.
- If cloud reset fails, switch to using a USB installation media:
- Create media with Media Creation Tool and perform reset or clean install offline.
- Ensure firewall/proxy settings don’t block downloads and that DNS resolves Microsoft servers.
Notes:
- Cloud reset downloads about 3–4 GB; use a reliable wired connection.
12. Missing or altered recovery partition
Why it causes the problem:
- OEMs often put a recovery partition with WinRE; deleting or modifying it prevents reset.
How to fix:
- Check existing partitions: open admin Command Prompt and run diskpart, then list disk, select disk 0, list partition.
- If recovery partition absent, either:
- Recreate WinRE from installation media (copy Winre.wim to C:\Windows\System32\Recovery and run reagentc /setreimage /path C:\Windows\System32\Recovery then reagentc /enable),
- Or create a recovery USB using Create a recovery drive (search in Start) on another PC and use it.
- Boot from recovery USB or install media to reset/reinstall.
Tip:
- Keep a recovery USB handy to avoid dependency on recovery partition.
Additional section — Backup & When to Use a Clean Install
Why add this:
- Sometimes reset repeatedly fails; knowing when to give up and do a clean install, and how to back up correctly, prevents data loss.
Backup before doing heavy fixes:
- Use File History or copy files manually to external storage (Desktop, Documents, Pictures, emails).
- Use disk imaging tools (Macrium Reflect Free, Acronis) to create a full disk image if possible.
When to choose a clean install:
- If repeated attempts to reset fail after repairing WinRE, SFC/DISM, and disk checks, or the system image is irreparably corrupted, a clean install from USB is the most reliable option.
How to perform a clean install:
- Create USB with Media Creation Tool.
- Boot from USB, choose Install now, opt to Custom: Install Windows only, delete system partitions (careful—this removes data), then install.
- Restore your files from backup.
Note:
- Keep license/product key info (linked to Microsoft account or embedded in firmware).
