By ErrorNest Published Updated 4 min read
Windows Update stuck on Checking for updates usually means a stalled service or a damaged update cache. These fixes run from safest to most involved, for Windows 10 and Windows 11.

If Windows Update stays on “Checking for updates” far longer than usual, the update service has usually stalled or its download cache is damaged. Low disk space, an unstable connection or a VPN can cause the same symptom. The fixes below run from the safest to the most involved, so stop as soon as updates start downloading.

Quick fix: Restart the PC, confirm you are online and not on a metered connection, then run the built-in Windows Update troubleshooter (step 2). This clears many stuck checks without changing anything else.

What makes Windows Update get stuck checking

  • The Windows Update or Background Intelligent Transfer Service (BITS) service has stopped responding.
  • Damaged files in the update download cache, the SoftwareDistribution folder.
  • Corrupted system files.
  • Not enough free space on the system drive, or a weak connection, proxy or VPN.
  • Updates are paused, or the connection is set as metered.

1. Wait, restart and check the basics

A first check after a long gap between updates can legitimately take a while, so give it about 30 minutes. If nothing changes, restart the PC and open Windows Update again. Then check three things:

  1. You can open a website, so the connection works. Turn off any VPN while testing.
  2. Updates are not paused. In Windows 11 go to Settings > Windows Update and select Resume updates if you see it.
  3. The system drive has free space. Large updates need several gigabytes.

2. Run the Windows Update troubleshooter

In Windows 11 open Settings > System > Troubleshoot > Other troubleshooters, find Windows Update and select Run. In Windows 10 open Settings > Update & Security > Troubleshoot > Additional troubleshooters and run Windows Update. Apply any fix it offers, restart, and check again.

3. Restart the update services

Press Win + R, type services.msc and press Enter. Find Windows Update, Background Intelligent Transfer Service and Cryptographic Services. Right-click each one and choose Restart (or Start if it is stopped). Then open Windows Update and select Check for updates.

4. Reset the update cache

Before you start: this renames Windows Update’s working folders. Your files and installed programs are not touched, but your update history view may reset. Windows recreates the folders automatically.

Open the Start menu, type cmd, right-click Command Prompt and choose Run as administrator. Run these commands one at a time:

net stop wuauserv
net stop bits
net stop cryptsvc
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start cryptsvc
net start bits
net start wuauserv

Restart the PC and check for updates again. Once updates work, you can delete the .old folders to free space.

5. Repair damaged system files

In the same administrator Command Prompt, run the two commands below in order. Each can take several minutes, and the progress bar may pause for a while.

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Restart when both finish, then try Windows Update again.

6. Install the update manually

If one specific update keeps failing, note its KB number from Windows Update, search for it in the Microsoft Update Catalog, and download the version that matches your Windows edition and system type (64-bit or Arm). Run the installer and restart.

7. Last resort: repair Windows in place

Back up important files first. In Windows 11 you can open Settings > System > Recovery and use Fix problems using Windows Update to reinstall the current version while keeping your files and apps. If that is not available, use Reset this PC and choose Keep my files.

Frequently asked questions

How long should “Checking for updates” take?

Usually a few minutes. If it has not moved after an hour and the PC is online, treat it as stuck and start with the troubleshooter.

Is it safe to rename the SoftwareDistribution folder?

Yes. It only holds downloaded update files and Windows rebuilds it. Renaming it is a standard reset, which is why we rename rather than delete.

Will I lose my files or programs?

Steps 1 to 6 do not remove personal files or installed programs. Back up before the repair in step 7.

When to contact support

If every step fails and Windows Update shows an error code, search for that exact code. If the PC is managed by an employer or school, an administrator may be blocking updates, so contact your IT team.
