Windows Update errors usually come down to one of a handful of causes: a stuck download, low disk space, a corrupted update file, or a driver conflict.
This guide covers how to fix Windows Update error problems, starting with the fastest option and working through to the deeper fixes if the quick ones don't resolve it.
Try This First
Before anything else, restart your PC. It sounds too simple to matter, but a large share of update failures clear up after a reboot Windows often just needs a clean session to finish what it started.
If that doesn't help, check your internet connection, then run the built-in Windows Update Troubleshooter (Settings > System > Troubleshoot > Other troubleshooters > Windows Update).
It catches a surprising number of common issues automatically. If the error is still there after that, keep reading the next sections go step by step.
Why Windows Update Fails
Windows Update is the background service that automates downloading and installing software updates for the operating system, according to Wikipedia. There isn't one single cause when that process breaks.
In practice, most failures trace back to a small set of recurring issues:
Corrupt update files left over from a previous failed attempt
Insufficient disk space — Windows needs breathing room to download and stage files before installing
Driver or hardware conflicts, especially with recently added peripherals
Interrupted downloads, often from an unstable connection or a background app blocking the process
Incorrect date and time settings, which can break the secure connection Windows Update relies on
Third-party antivirus or firewall software occasionally flags or blocks update components
Knowing the likely cause doesn't always tell you the fix outright, but it narrows where to look first.
Before You Start: A Quick Checklist
A few basics are worth confirming before you touch any settings:
Back up personal files, just in case
Free up at least 15–20 GB of disk space
Confirm you're signed in with an administrator account
Disconnect USB drives, docks, printers, and anything not essential
Plug in laptops to AC power rather than running on battery
Skipping this step is usually fine for a one-off glitch. It matters more when an update has already failed once or twice.
How to Fix Windows Update Error: General Troubleshooting Steps
Work through these in order. Most people resolve their issue somewhere in the first five.
Step 1: Run the Windows Update Troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters, then run Windows Update. It diagnoses common problems automatically and, in many cases, fixes them without further input.
Step 2: Check Your Internet Connection
Go to Settings > Network & Internet and confirm you're connected. An unstable connection is a common, easy-to-miss cause of interrupted downloads.
Step 3: Confirm Administrator Access
Some updates require an administrator account. If you're on a standard account, either switch to an admin account or ask whoever manages the device to run the update.
Step 4: Disconnect External Hardware
Unplug USB drives, external monitors, docks, and printers that aren't essential. Reconnect them after the update completes.
Step 5: Check Date and Time Settings
Go to Settings > Time & Language > Date & Time, and turn on "Set time automatically." An incorrect clock can quietly break the update's security handshake.
Step 6: Free Up Disk Space
Use Storage settings (Settings > System > Storage > Cleanup recommendations) to clear temporary files. Windows generally needs 16–20 GB of free space depending on the update type.
Step 7: Temporarily Disable Antivirus or Firewall
Some third-party security tools interfere with update components. Pause protection briefly, run the update, then turn it back on.

Step 8: Update Device Drivers
Outdated or mismatched drivers — particularly graphics and network drivers — sometimes block installation. Check the manufacturer's site or Device Manager for updates.

Step 9: Restart and Check Again
After working through the above, restart your PC and check for updates once more. Sometimes an update simply needed the groundwork cleared before it could proceed.
Finding Your Windows Update Error Code
If the general steps don't fix it, the error code itself is the fastest route to a targeted fix. It appears in Settings > Windows Update, usually right below the failed update entry, formatted like 0x8007000d.
That code is worth writing down it points to a specific cause rather than a general one.
Windows Update Error Codes: Causes and Fixes
Error Code | Likely Cause | Recommended Fix |
0x8007000d | Corrupted update cache | Clear the SoftwareDistribution folder, then retry |
0x800705b4 | Update timed out or was interrupted | Check connection, temporarily disable antivirus, restart |
0x80240034 | Update process stuck | Confirm Windows Update service is running, run troubleshooter |
0x800f0922 | Low disk space or component conflict | Free up space, disable VPN if active |
0x80070057 / 0x80080005 | Corrupted system files or permission issue | Run System File Checker (sfc /scannow) |
0xC1900101 | Driver incompatibility | Update or temporarily uninstall the conflicting driver |
0x80248014 | Update service or database issue | Restart the Windows Update service |
0x80070005 | Access denied / permissions error | Confirm administrator access, disable antivirus temporarily |
0x80070002 / 0x80070003 | File or path not found | Reset Windows Update components (see below) |
0x8024402F / 0x80244022 | Connectivity or update service not running | Check connection, restart Windows Update service |
Most of these fixes point back to the general steps above. The main exception is resetting the Windows Update components directly, which is worth covering on its own.
Windows Update Stuck at a Percentage
It's common for an update to sit at a specific number 0%, 51%, or 100% — for what feels like too long. Large updates can genuinely take 20–30 minutes at certain stages, so some patience is warranted before assuming something's wrong.
As a rough guideline, if the percentage hasn't moved in over 45 minutes and the disk activity light isn't flickering, it's reasonable to treat it as stuck.
Restart the PC, reconnect to the internet if needed, and run the update again. Interrupting an update mid-installation is not ideal, but it's rarely damaging on modern versions of Windows it will typically resume or restart the process on the next boot.
Advanced Troubleshooting for Persistent Errors
These steps require a bit more comfort with Command Prompt. They're not risky when followed correctly, but they go deeper than the settings menu.
How to Fix Windows Update Error by Resetting Update Components
Open Command Prompt as administrator and run:
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
This clears out corrupted update files and forces Windows to rebuild them from scratch. In practice, this resolves a large share of the errors that general troubleshooting alone doesn't touch.
Run System File Checker (SFC)
Open Command Prompt as administrator and run sfc /scannow. It checks core system files against a known-good copy and repairs anything corrupted. The scan typically takes 15–30 minutes.
Run DISM to Repair the System Image
If SFC alone doesn't help, run DISM /Online /Cleanup-image /Restorehealth first, then follow with sfc /scannow. DISM repairs the underlying Windows image that SFC relies on, so running them in that order tends to work better than either alone.
Check the Disk for Errors
Run chkdsk /f C: from an administrator Command Prompt. This checks for and repairs disk errors that can silently interfere with installation.
Try a Clean Boot
A clean boot starts Windows with a minimal set of drivers and startup programs, which helps rule out software conflicts.
It's a diagnostic step more than a permanent fix, but it's useful for isolating the cause.
What to Do If Nothing Works
If you've worked through everything above and the update still fails, a few options remain:
Restore from a System Restore point, if one exists from before the issue started. Note this restores system files and settings only — not personal documents or photos.
Download the update manually from the Microsoft Update Catalog using the KB number shown in the error message, then install it directly.
Reset the PC while keeping personal files (Settings > System > Recovery > Reset this PC).
Perform a clean installation of Windows, which is the most disruptive option and generally treated as a last resort rather than a first attempt.
Teams that manage multiple devices commonly report that persistent update failures on a handful of machines, after all the standard steps fail, often trace back to disk hardware issues rather than the update itself which is part of why a disk check earlier in the process is worth doing rather than skipping.
How to Prevent Future Update Errors
A few habits reduce how often this comes up again:
Keep automatic updates turned on rather than manually delaying them
Maintain more free disk space than the bare minimum
Keep drivers reasonably current, particularly graphics and network drivers
Restart the PC periodically instead of leaving it in sleep mode for weeks at a time
None of this guarantees a flawless update every time. It does noticeably cut down how often you'll need to troubleshoot one.
Conclusion
Most Windows Update errors resolve with a restart, a troubleshooter run, or a bit of freed-up disk space.
Persistent errors usually need the specific error code and a targeted fix. Advanced tools like SFC and DISM cover what's left.
FAQ
What does it mean when Windows Update fails repeatedly?
It usually points to a recurring cause low disk space, a corrupted file, or a driver conflict rather than a one-off glitch. Checking the specific error code helps identify which.
Is it safe to turn off my PC while an update is stuck?
It's not ideal, but modern Windows versions generally recover on the next restart. If it's genuinely stuck rather than just slow, restarting is usually the right call.
Do I need administrator access to fix update errors?
For most fixes, yes. Standard accounts can run the troubleshooter, but deeper fixes like resetting update components need admin rights.
How much free space does Windows need to update?
Roughly 16–20 GB, depending on the update type and whether it's a feature update or a smaller cumulative one.
How long should an SFC or DISM scan take?
Usually 15–30 minutes each. Longer isn't necessarily a problem, but if it sits at 0% with no progress for well over an hour, it's worth restarting and trying again.
