Fix #1: Restart Windows Installer service
This is the best fix of all the below solutions to fix windows update error.

- Type services.msc.
- Click the tab “Standard”.
- Then sort the services based on name.

- Then you can set the Startup Type also as “Automatic”.
This worked for me in Windows 7.
Fix #2: Provide Write permission to Catroot2 folder.
If Windows Update process fails to write files to Catroot2 folder, then also this error can occur.
So you need to remove read permission for that folder. Or give access to Windows Update to write to this folder.
This can be done in this way.
- Press the Win key and type “cmd”.
- Right-click the command prompt app and run as administrator.
In older versions of Windows 10, you can also right-click the Start button and find it.
- Command prompt window opens.
- Type the following commands.
attrib -h -s -r c:\windows\system32\catroot2 attrib -h -s -r c:\windows\system32\catroot2\*.*
- C: is the Windows drive or where Windows 10 is installed.
- Press Enter after each command.
This will give write access to Catroot2 folder to Windows Update program.
Fix #3: Start, Stop, Restart Cryptographic Service
This is another service which causes the error code 80246005.
- Open “Services” as mentioned earlier.
- Find the “Cryptographic Services”.
- Stop and Restart it, if it is running.
- Otherwise, just start it.
Fix #4: Start BITS, Windows Update and other Services
In Windows 10, you can find some other services related to Windows Update. These are the following.
- Background Intelligent Transfer Service
- Windows Update
- Windows Defender Firewall
Also make sure your system time is correct. Check whether your CMOS battery is working on your laptop or pc. Otherwise, update to the latest time using Internet services.
These are the two main services connected to update Windows 10 or 8.1 to the latest version. If they are not working, then also error code 80246005 can occur.
You can start them. Otherwise, restart them.
Fix #5: Windows Update Troubleshooter
This can be done in different ways in Windows 7 or 10. I will mention the new method in Windows 10.

- Click on “Update & Security”.
- Scroll through, to click on “Troubleshoot”.
