The good news is that this problem is often fixable without reinstalling Windows. In this guide, you will learn the real causes of error 0x80070002 and several proven methods to solve it.
What Is Windows Update Error 0x80070002?
Error code 0x80070002 indicates that Windows Update cannot access or verify important update files. In many cases, the system attempts to download or install an update but fails because some files are missing, corrupted, or inaccessible.
Users may see messages such as:

Common Causes of Error 0x80070002

Windows security verification depends on accurate time settings. Incorrect time zones or dates can interrupt updates.
4. Interrupted Updates
Power outages, forced shutdowns, or unstable internet connections may damage update components.
5. Disabled Windows Services
Important services like Windows Update or Background Intelligent Transfer Service (BITS) must remain active.

Some third-party antivirus applications may block Windows Update processes.

Below are the most effective methods to fix Windows Update Error 0x80070002. Follow each solution carefully step by step until the update problem is completely resolved on your Windows PC.

Steps
- Press Windows + R
- Type:
services.msc
- Press Enter
- Locate these services:
- Windows Update
- Background Intelligent Transfer Service
- Cryptographic Services
- Right-click each service and select Restart
After restarting the services, try checking for updates again.
Method 2 — Run the Windows Update Troubleshooter
Microsoft includes a built-in troubleshooter that can automatically detect and fix Windows Update issues. It scans the system and repairs common errors quickly.

- Open Settings
- Go to:
- System → Troubleshoot → Other troubleshooters
- Find Windows Update
- Click Run
On Windows 10
- Open Settings
- Go to:
- Update & Security → Troubleshoot

The tool may automatically repair damaged update components.
Method 3 — Delete the SoftwareDistribution Folder
The SoftwareDistribution folder stores temporary Windows Update files. Deleting its contents often resolves error 0x80070002 and update installation problems quickly.
Step 1 — Stop Update Services
Open Command Prompt as Administrator and run:
net stop wuauserv
net stop bits
Step 2 — Delete Cached Files
Open File Explorer and go to:

Restart the computer and try updating again.
Method 4 — Repair Corrupted System Files
Damaged system files can interfere with Windows Update.
Run System File Checker

Method 5 — Check Date and Time Settings
Incorrect system time may prevent update verification.
Fix Time Settings
- Open Settings

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start bits

net start msiserver
Restart your computer after running the commands.
Method 7 — Install Updates Manually
Sometimes Windows Update itself fails, but manual installation still works.
Steps
