Windows Update Error Code 0x80070005 is a common issue of permissions or access denied and usually occurs when trying to update the system. This error prompts "Access is denied", most of which are related to user permissions, system services, security software or system files corruption. Below are some practical and effective solutions, arranged from simple to traditional according to operation difficulty.

1. Run Windows Update as an administrator

Make sure you are using an administrator account and start the update service with administrator privileges.

• Click "Start" → Search for "cmd"
• Right-click on "Command Prompt" → select "Run as Administrator"
• Enter the following command and execute it one by one:

   net stop wuauserv
  net stop cryptSvc
  net stop bits
  net stop msserver

• Then restart these services:

   net start wuauserv
  net start cryptSvc
  net start bits
  net start msserver

• Close the command prompt and try checking for updates.

This operation will reset Windows Update related services to solve the permissions problems caused by service stuck.

2. Check whether your user account is an administrator

Error 0x80070005 Sometimes it is because the current account does not have sufficient permissions.

• Press Win I to open Settings → Account → Home and Other Users
• Check if your account type is "Administrator"
• If not, switch to administrator account or create a new administrator account and try the update again after logging in

3. Turn off third-party antivirus software or firewall

Certain security software (such as McAfee, Norton, 360, Turf, etc.) prevents Windows Update from writing to system files.

• Temporarily turn off real-time protection of antivirus software
• Disable third-party firewalls
• Try running Windows Update again

It is recommended to turn on the protection again after the update is completed.

4. Use the built-in Windows Update troubleshooting tool

Troubleshooting that comes with Windows can automatically detect and fix some update issues.

• Open Settings → Update & Security → Troubleshooting
• Select "Other Troubleshooting"
• Automatic repair tool running "Windows Update"
• Follow the prompts to apply the recommended fixes

5. Reset Windows Update components (Advanced operations)

If the above method is invalid, it may be that the Windows Update component itself is corrupted.

Open a command prompt as an administrator and execute the following commands:

 net stop wuauserv
net stop cryptSvc
net stop bits
net stop msserver

Then rename the software distribution folder and encrypt cache:

 ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old

Then restart the service:

 net start wuauserv
net start cryptSvc
net start bits
net start msserver

Restart the computer and check for updates again.

This operation clears the update cache and the system will re-download the update file, which may take some time.

6. Check system file integrity

Corruption of system critical files may also lead to permission errors.

• Open a command prompt as administrator
• enter:

   sfc /scannow

• Wait for the scan to complete (may take 10-20 minutes)
• If the prompt "Corrupt file found but cannot be repaired", run again:

   DISM /Online /Cleanup-Image /RestoreHealth

• After completion, restart the computer and try to update

7. Check the time and area settings

An incorrect system time or time zone will cause the update server to fail to verify, which will indirectly raise permission errors.

• Right-click on the taskbar time → Adjust date and time
• Make sure "Auto Set Time" and "Auto Set Time Zone" are turned on
• The time must be consistent with the current actual time (the error cannot exceed several minutes)

summary

Error 0x80070005 In most cases, it is not a serious system failure, but a permission or service blocked. Recommended to try in order:

• Restart Windows Update Service
• Make sure to use the administrator account
• Turn off third-party security software
• Reset update cache (SoftwareDistribution)
• Run SFC and DISM to repair system files

Basically that's it. Not complicated, but it is easy to ignore details.
