How to Fix a Windows Update Stuck on Pending Install

If Windows Update is stuck on “Pending install,” restart the PC first, then check Windows Update again. That status usually means the update has downloaded but Windows has not started the installation phase. If a restart does not clear it, work through storage, the built-in troubleshooter, system-file repair, and finally a Windows Update component reset.

The steps below apply to Windows 11 and Windows 10, with path differences noted. Microsoft ended regular Windows 10 support on October 14, 2025, so a Windows 10 PC normally needs Windows 11, an eligible Extended Security Updates (ESU) enrollment, or another supported Windows edition to keep receiving applicable security updates. See Microsoft’s Windows 10 end-of-support guidance.

1. Restart Windows and finish any pending restart

Some updates cannot continue until an earlier update finishes during a reboot. Do a real restart rather than shutting the lid or putting the PC to sleep.

1. Save your work and close open apps.
2. Open Start > Power and select Restart. If Update and restart appears, use that option.
3. After signing back in, open Settings > Windows Update on Windows 11. On Windows 10, open Settings > Update & Security > Windows Update.
4. Select Check for updates, Resume updates, or Retry if Windows shows one of those actions.

2. Check the connection, power, and free storage

Microsoft’s current Windows Update troubleshooting guidance recommends a stable internet connection, power for portable devices, administrator access when required, and disconnecting nonessential external hardware while troubleshooting. Low free space can also prevent Windows from staging or installing an update.

• Plug in a laptop or tablet before retrying the update.
• Confirm Wi-Fi or Ethernet is working normally.
• Disconnect unnecessary USB storage devices, docks, and other nonessential accessories.
• Open Settings > System > Storage and make room on the Windows drive if it is nearly full.

Windows can remove temporary files through Storage settings and Storage Sense. Microsoft documents the supported cleanup methods in Free up drive space in Windows.

3. Run the Windows Update troubleshooter

Use Microsoft’s automated troubleshooter before changing services or deleting update folders manually.

• Windows 11: go to Settings > System > Troubleshoot > Other troubleshooters, find Windows Update, and select Run. Current Windows builds may continue the diagnostic flow in the Get Help app.
• Windows 10: go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update, then run the troubleshooter. Get Help can also guide you through update problems.

Follow any recommended fix, restart, and check for updates again. Microsoft maintains the current procedure in Troubleshoot problems updating Windows.

4. Repair Windows with DISM and System File Checker

If the update repeatedly remains pending or fails after downloading, damaged Windows component files may be involved. Microsoft recommends running DISM before System File Checker.

1. Open Command Prompt (Admin), Windows Terminal (Admin), or an elevated PowerShell window.
2. Run DISM.exe /Online /Cleanup-Image /RestoreHealth and let it finish.
3. Then run sfc /scannow and keep the window open until verification reaches 100%.
4. Restart Windows and check for updates again.

These commands and their expected behavior are documented by Microsoft in Use the System File Checker tool to repair missing or corrupted system files.

5. Reset the Windows Update download cache

If the earlier fixes do not work, reset the update cache from an elevated Command Prompt. Microsoft lists this as a fallback after the troubleshooter. This removes cached update files so Windows can download clean copies; it does not delete your personal documents.

net stop wuauserv
rd /s /q %systemroot%\SoftwareDistribution
net start wuauserv

Restart the PC after the commands finish, return to Windows Update, and select Check for updates. For the longer component-reset procedure, use Microsoft’s current Windows Update component reset instructions rather than copying an old script from another version of Windows.

6. If the update is still pending

Open Update history and note the update’s KB number and any error code. Search that exact KB on Microsoft Support to check for prerequisites or known issues, and use Microsoft’s Windows Update troubleshooting page for the specific error code. If Windows itself is unstable after DISM, SFC, and an update-component reset, back up important files before moving to Windows recovery or repair-install options.

Avoid randomly deleting other folders under C:\Windows or forcing old service-startup tweaks. Windows Update manages several services and components itself, and current Microsoft troubleshooting starts with restart, connectivity and storage checks, the troubleshooter, repair tools, and only then a component reset.
