If you receive Windows Update error 80246005 while checking for updates, it usually means either you cannot save files to the Catroot2 folder, or that the Cryptographic Service was not started or is not
working properly. Follow the steps below to correct these problems.
To allow files to be saved in the Catroot2 folder
Windows Update might fail if
Windows cannot copy files to the Catroot2 folder or replace files that are in that folder (for example, if the folder or its files are set to read-only). To change the folder so you can write files to it, follow these steps:
Click the Start button .
In the Search box, type command prompt.
In the list of results, right-click Command Prompt, and then click
Run as administrator. If
you are prompted for an administrator password or confirmation, type the password or provide confirmation.
At the Command Prompt window, type attrib -h -s -r c:\windows\system32\catroot2 (where c:\ is the drive where
Windows is installed), and then press ENTER.
Next, type attrib -h -s -r c:\windows\system32\catroot2\*.* (where c:\ is the drive where
Windows is installed), and then press ENTER.
Type Exit, and then press ENTER to close the Command Prompt window.
To check and restart the Cryptographic Service
Open Administrative Tools by clicking the
Start button ,
clicking Control Panel, clicking System and Maintenance, and then clicking
Administrative Tools.
Double-click Services. If
you are prompted for an administrator password or confirmation, type the password or provide confirmation.
In the Services dialog box, click Windows Update (you might need to scroll down to find it; the entries are in alphabetical order).
Note the status of the selection (the status appears in the third column). Right-click
Windows Update and do one of the following:
If Start is available, click
Start.
If Restart is available, click
Restart.
Now click Cryptographic Services (you might need to scroll up to find it).
Note the status of the selection (the status appears in the third column). Right-click
Cryptographic Services and do one of the following:
If Start is available, click
Start.
If Restart is available, click
Restart.
Close the Services dialog box.
After trying either of these procedures, go to the
Windows Update website and try checking for updates again.
That should fix the issue.
Thank you.
