Errror in WUAHandler.log:

Scan failed with error = 0x80072efe.

Step 1: Check background programs.

=======================

Disable firewalls or other Internet browser programs that can affect the Internet connection. The following programs can affect the connection to the Windows Update site and I suggest you remove or disable them:

McAfee firewall

Norton Internet Security

Zone Alarm Firewall

Panda firewall

Step 2: Delete the CatRoot2 folder

=======================

A: Stop Cryptographic Services:

1. Click Start, click Run, type in "SERVICES.MSC" and press Enter.

2. Double click Cryptographic Services, and then click Stop (if it has been started).

B: After stopping Cryptographic Service, please delete the "Catroot2" folder:

1. Locate the "C:\Windows\System32\" folder.

2. Delete the Catroot2 subfolder in System32.

Note: I am assuming your Windows Vista is installed in C:\Windows.

C: Re-start Cryptographic Services:

1. Click Start, click Run, type in "SERVICES.MSC" and press Enter.

2. Double click Cryptographic Services, and then click Start.
