Why Is Windows Update Taking So Long?
If your Windows update is:
- Downloading very slowly

How Long Should a Windows Update Take?
Normal update times:
- Small security update → 10–20 minutes
- Monthly cumulative update → 20–60 minutes
- Major feature update → 1–2 hours
If it takes more than 3 hours with no disk activity, something is wrong.
First: Check If It’s Actually Working
Open Task Manager and check:
✔ Disk usage
✔ CPU usage
✔ Network activity
If there is activity, wait at least 30–60 minutes.
If everything shows 0% activity for a long time, continue below.
Fix 1: Restart Your Computer
If update appears frozen:
- Hold Power button for 10 seconds
- Turn PC back on
Windows will either:
- Continue installation
OR - Roll back automatically
Most of the time, no data is lost.
Fix 2: Free Up Disk Space
Low disk space is a very common cause.
Recommended:
- At least 20–30 GB free for feature updates
Delete:
- Temporary files
- Old downloads
- Unused programs

Old HDD drives especially slow down updates significantly.
Fix 3: Clear Windows Update Cache
Corrupted cache can make update appear endless.
Open Command Prompt (Admin):
net stop wuauserv
net stop bits
net stop cryptsvc
net stop msiserver
Go to:
C:\Windows\SoftwareDistribution
Delete all contents.
Restart services:
net start wuauserv
net start bits
net start cryptsvc
net start msiserver
Restart PC.
This also helps if you’re facing 0x80070002 or 0x800f0922 errors.
Fix 4: Check Internet Speed
Slow download = slow update.
Test your internet speed.
If speed is unstable:
- Restart router
- Switch from WiFi to Ethernet
- Disable VPN
Network problems are also common in 0x8024402C cases.
Fix 5: Run Windows Update Troubleshooter
Windows 11:
Settings → System → Troubleshoot → Other troubleshooters → Windows Update
Apply fixes automatically.
Fix 6: Run SFC and DISM
Corrupted system files can slow installation dramatically.
Open Command Prompt (Admin):
sfc /scannow
Then:
DISM /Online /Cleanup-Image /RestoreHealth
Restart PC.
Fix 7: Perform a Clean Boot
Background apps may conflict with updates.
- Press Windows + R
- Type:
msconfig
- Disable non-Microsoft services
- Restart
Try updating again.
Fix 8: Upgrade to SSD (Long-Term Fix)
If you’re still using HDD:
Windows updates will always feel slow.
Switching to SSD can:
- Cut update time by 50–70%
- Improve boot speed
- Improve overall system performance
This is the biggest long-term performance upgrade.
