Quick Checks Before You Start

Run through this short list before trying the fixes. One of these is often the whole problem.

• Your PC or laptop is plugged into power. Windows may slow or pause downloads on battery.
• You are connected to the internet, ideally not on a metered or very slow connection.
• Your C: drive has plenty of free space (see Fix 5).
• No VPN or proxy is currently active, since these can interfere with Microsoft’s update servers.
• You are signed in with an administrator account, because some update actions need admin rights.

Diagnose the Problem

Symptom	Likely cause	Go to fix
Stuck at 0% for a long time	No working connection, or the download never started	Fix 3
Percentage has not moved for hours	Corrupted or incomplete download files	Fix 8
Stuck at a high percentage (90% or more)	Low disk space or a driver conflict	Fix 5
Download keeps restarting from the beginning	Broken Windows Update components	Fix 10
Update fails with an error code	Damaged system files	Fix 9

1. Give It More Time — The Download May Still Be Working

This sounds too simple, but it is the most skipped step. Windows Update does not always show smooth progress. The percentage can sit still for a long time while large files download in the background, especially with big feature updates. Slow Microsoft servers or a busy home network can also make a healthy download look frozen.

• Wait at least one to two hours before assuming the update is truly stuck.
• During the wait, avoid running heavy downloads, video calls, or large uploads on the same network.
• Check the percentage again after the wait. If it has moved even a little, the download is working — let it finish.
• If the number has not changed at all after two hours, move on to Fix 2.

2. Restart Your PC

A restart clears temporary glitches in the update service and gives the download a clean start. It is safe to restart while an update is still in the downloading phase, before installation begins.

• Save your work and close your open programs.
• Select Start, then Power, then Restart.
• After the restart, go to Settings > Windows Update.
• Select Check for updates and watch whether the download starts moving.
• If it stalls again at the same point, continue with Fix 3.

3. Check Your Internet Connection

Windows Update cannot download anything over a broken or unstable connection. A weak Wi-Fi signal is one of the top reasons a download freezes partway through. If your connection itself is the problem, start by fixing your internet connection first, since no update trick will help until the network is stable.

• Look at the Wi-Fi or network icon in the taskbar. Make sure you are actually connected.
• Open a website in your browser. If pages load slowly or not at all, the network is the issue.
• Restart your router: unplug it for 30 seconds, plug it back in, and wait for it to reconnect.
• If possible, switch from Wi-Fi to a wired Ethernet cable for a faster, steadier download.
• Turn off any VPN temporarily and try the update again.

4. Pause and Resume the Update

Pausing and resuming forces Windows Update to re-establish its connection to the update servers. This often unsticks a download that froze halfway.

• Open Settings and go to Windows Update.
• Select Pause updates and choose Pause for 1 week.
• Wait about one minute.
• Select Resume updates.
• Select Check for updates and see if the download restarts and progresses.

5. Free Up Disk Space

Windows needs free space not just for the final update, but for the temporary files it downloads along the way. If your drive is nearly full, the download can stall with no clear error message. Microsoft notes that devices need a healthy amount of free space for updates to install properly.

• Open Settings > System > Storage to see how much free space you have.
• Turn on Storage Sense to let Windows clean temporary files automatically.
• Empty the Recycle Bin.
• Uninstall apps and games you no longer use.
• Move large personal files, such as videos, to an external drive or cloud storage.
• After freeing space, restart your PC and check for updates again.

6. Run the Windows Update Troubleshooter for a Windows Update Stuck Downloading Error

Windows 11 includes a built-in troubleshooter that automatically finds and repairs common update problems. It is quick, safe, and worth running before trying manual fixes. Microsoft also publishes an official Windows Update troubleshooter guide with the same steps if you want a second reference.

• Open Settings > System > Troubleshoot.
• Select Other troubleshooters.
• Find Windows Update in the list and select Run.
• Follow the on-screen instructions and let it finish.
• Restart your PC when the troubleshooter completes.
• Go back to Settings > Windows Update and select Check for updates.

7. Restart the Windows Update Service

The Windows Update service itself can get into a bad state. Restarting it is like turning the engine off and on again — it often clears whatever was blocking the download.

• Press Win + R, type services.msc, and press Enter.
• In the Services window, scroll down to Windows Update.
• Right-click it and select Restart.
• If it is stuck on “Stopping” for more than a few minutes, restart your PC instead.
• After the service restarts, check for updates again in Settings > Windows Update.

8. Clear the SoftwareDistribution Folder

Windows stores downloaded update files in a folder called SoftwareDistribution. If those files are corrupted, every new download attempt can stall at the same point. Clearing the folder forces Windows to download fresh copies. This only removes temporary update files — your personal files, apps, and settings are not touched.

• Press Win + R, type services.msc, and press Enter.
• Right-click Windows Update and select Stop.
• Open File Explorer and go to C:\Windows\SoftwareDistribution\Download.
• Select everything inside the Download folder and delete it.
• Go back to the Services window, right-click Windows Update, and select Start.
• Open Settings > Windows Update and select Check for updates.

9. Repair System Files With SFC and DISM

Damaged Windows system files can prevent updates from downloading or installing correctly. Two built-in tools — SFC (System File Checker) and DISM — scan your system and repair corrupted files. Both are made by Microsoft and completely safe to run.

• Right-click Start and select Terminal (Admin) or Command Prompt (Admin).
• Type the following command and press Enter:
• DISM.exe /Online /Cleanup-image /Restorehealth
• Wait for it to finish. This can take 10 to 20 minutes.
• Next, type the following command and press Enter:
• sfc /scannow
• Wait for the scan to complete, then restart your PC.
• Check for updates again.

10. Reset the Windows Update Components

If nothing above worked, the update components themselves may be damaged. Resetting them stops the related services, renames the update cache folders so Windows rebuilds them fresh, and starts everything again. Run each command one at a time and wait for each to finish.

• Right-click Start and select Terminal (Admin).
• Run these commands one at a time, pressing Enter after each command.
• net stop wuauserv
• net stop cryptSvc
• net stop bits
• net stop msiserver
• ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
• ren C:\Windows\System32\catroot2 Catroot2.old
• net start wuauserv
• net start cryptSvc
• net start bits
• net start msiserver
• Restart your PC.
• Open Settings > Windows Update and select Check for updates.

What to Avoid

• Do not download “Windows Update fixer” or “driver updater” tools from random websites. Many bundle unwanted software, and some are outright malware. Stick to Microsoft’s built-in tools.
• Do not delete the entire SoftwareDistribution folder — only clear the contents of its Download subfolder, as described in Fix 8.
• Do not force-shutdown your PC repeatedly while updates are downloading. One clean restart is fine; hard shutdowns can corrupt files.
• Do not disable Windows Update permanently as a workaround. That leaves your PC without security fixes.
• Do not edit the Windows registry to fix update downloads unless you know exactly what you are doing. A wrong change can stop Windows from booting.

FAQ

How long should I wait before deciding the update is stuck?

If the percentage has not moved at all for two hours on a normal home connection, it is reasonable to call it stuck and start with Fix 2. Very large feature updates on slow connections can legitimately take longer, so consider your internet speed before acting.

Is it safe to restart my PC while an update is downloading?

Yes, during the downloading phase a restart is safe. The risk comes later, during the installation phase when Windows says “Do not turn off your computer.” A frozen download screen is still in the safe zone.

Why does Windows Update get stuck at 0%?

A 0% stall usually means the download never properly started. The most common causes are a broken internet connection, the Windows Update service not running, or corrupted files in the download cache. Fixes 3, 7, and 8 address these directly.

Will clearing the SoftwareDistribution folder delete my files?

No. That folder only holds temporary Windows Update files. Your documents, photos, apps, and settings are stored elsewhere and are completely unaffected.
