How to Fix Windows Update Stuck Checking for Updates
Quick answer
Wait a bit on a slow connection, checking really can take a while. If nothing changes for more than an hour, restart the PC, confirm you have disk space and internet, then run Windows's own Windows Update troubleshooter. Avoid third-party "update repair" downloads.
Quick diagnosis
If several of these match what you see, you are in the right guide.
- Settings → Windows Update never finishes "Checking for updates"
- The spinner runs for hours
- You cannot install a needed security update
Possible causes
- A large update is downloading slowly in the background
- The update service is stuck
- Disk space is too low
- A corrupted update cache
- Network filtering (some workplace networks) blocking Microsoft update servers
What you need
- An internet connection that otherwise works
- Administrator permission for some later steps
What this problem usually means
Windows Update has to reach Microsoft, compare what you already have, and sometimes download a large package. "Stuck" might be a frozen service, or it might be a download with no useful progress text. A working internet connection for websites does not always mean update servers are reachable (common on locked-down work networks).
The useful question is whether the state is changing. A named update, disk activity, or network activity means Windows may still be working. A spinner with no update name after a restart and an hour of waiting is a better sign that the update service or cache is stuck.
Before you start
- Plug in a laptop. Large updates should not run down the battery unnoticed.
- Confirm File Explorer shows several gigabytes free on C:.
- If this is a work PC, ask IT before running reset steps, they may manage updates for you.
Download Windows only from Microsoft if you ever need installation media. Random ISOs are a malware risk.
Quick fixes
1. Wait, then refresh
- Leave the Windows Update page open for 15 to 20 minutes on a slow link.
- Open Task Manager and glance at Network and Disk. Some activity means Windows may still be checking or downloading.
- Close Settings and reopen it. If a percentage or a specific update name appears, let it finish.
If nothing changes for more than an hour after a restart, move from waiting to repair steps. Do not run reset commands repeatedly while a named update is actively installing.
2. Restart
A restart is the right first repair. After sign-in, wait a few minutes, then check Windows Update again. The PC may feel slow while it checks, that overlaps with a slow Windows 11 PC.
3. Confirm internet works
Open a couple of websites. If you have no internet, fix that first, Wi-Fi connected but no internet.
Step-by-step troubleshooting
Separate a slow check from a failed check
- If a specific update name appears, let it download or install unless the PC is unusable.
- If an error code appears, use the Windows error code lookup or the failed update guide.
- If the page says only "Checking for updates" after restart and an hour, continue with the troubleshooter and service restart.
Run the Windows Update troubleshooter
- Open Settings → System → Troubleshoot → Other troubleshooters.
- Run Windows Update and apply what it offers.
- Restart if it asks, then check for updates again.
Pause and resume updates
On Windows 11, Windows Update includes Pause. Pause for a week, restart, then turn pause off. This sometimes unsticks a hung check. Do not leave updates paused permanently, you will miss security fixes.
When an error code appears
If checking fails with a code such as 0x80070057 or 0x80070422, look it up in our error code lookup instead of repeating the same click. The code is a clue, not a single magic fix.
Advanced: restart update services (administrator)
Only if the troubleshooter did not help. You will stop the Windows Update service, then start it again. This is a reset of the service, not a disk wipe.
Administrator Command Prompt
net stop wuauserv- What this does
- Stops the Windows Update service.
- Why run it
- A stuck service will not finish "checking." Stopping it lets Windows start a clean instance.
- What you should see
- A message that the service was stopped, or that it was not running.
- If it fails
- You must use an Administrator Command Prompt. If the service refuses to stop, restart the PC and try once more. Do not disable the service permanently.
Administrator Command Prompt
net start wuauserv- What this does
- Starts the Windows Update service again.
- Why run it
- Updates cannot check while the service is left off.
- What you should see
- A message that the service was started successfully.
- If it fails
- Restart the PC. If it still fails, the troubleshooter or a repair install (from Microsoft's own media) is the next conversation, not a random registry script.
Is Windows Update really stuck?
Choose an answer. The next question appears below, no account or download required.
Let it continue unless it has made no progress for hours. A named update is more useful than the generic checking spinner.
Use the error code lookup or failed-update guide. The code changes the next step, so do not keep clicking Check for updates.
Run the Windows Update troubleshooter, confirm free space and internet, then restart the update service once as an administrator.
Restart once, plug in the laptop, and give Windows a fair check window. Then continue only if the state does not change.
How to know the problem is fixed
- Windows Update shows either "You're up to date" or a named update with progress, not an endless check.
- After install, the PC restarts if asked and still boots to the desktop.
If the problem continues
On a home PC, Microsoft's official "Download Windows 11" installation assistant or a repair from official media is the heavy option. Back up files first. On a work PC, stop and ticket IT, they may block consumer update paths on purpose.
When this may be hardware failure
Updates that fail because the drive reports errors, or the PC crashes mid-install, can be a failing SSD or HDD. Back up files. A stuck checker with a healthy disk and working internet is usually software, not a dead motherboard.
Common mistakes to avoid
- Downloading a third-party Windows Update "repair kit."
- Deleting the Windows folder to "clear the cache."
- Leaving the update service disabled so checking never runs again.
- Ignoring a full C: drive.
Frequently asked questions
How long should "Checking for updates" take?
A few minutes is common. More than an hour with no change after a restart is stuck. Overnight on a very slow connection can still be a download in disguise, look for disk or network activity in Task Manager.
Can I turn off Windows Update to speed up the PC?
You can pause briefly. Turning it off for good is a security problem. If updates make the PC slow, let them finish, then use the performance guide.
What if Windows Update shows an error code instead?
Stop treating it as a generic stuck-checking problem. Write down the code and use the error-code lookup or failed-update guide because disk space, services, and update-cache fixes apply differently by code.
