Windows could not search for updates. Error 40008002. Windows Update occurred an unknown error.

Try "Driver Tuner"
It might works

You may receive an error message when you search for available updates...

To resolve this error, examine the Hosts file. (This file may also be named Hosts.sam.) Make sure that the file does not list any static IP entries for the Windows Update Web site or for the Microsoft Update Web site.

The Hosts file is located in the C:\Windows\system32\drivers\etc folder. To view the Hosts file, you may have to associate the file with Notepad. To do this, follow these steps:

1. Right-click the Hosts file.
2. Click Open With, and then select Notepad from the list of programs.

If the Hosts file contains a static IP address that is associated with Windows Update or with Microsoft Update, comment the entry by adding the # sign at the beginning of the entry. You can also delete the whole line and save changes to the Hosts file.

Note Programs, such as Web accelerators, DNS accelerators, DNS caching utilities, and Spyblockers, can add static IP entries for the Windows Update Web site or for the Microsoft Update Web site to your Hosts file. This scenario can cause Windows Update or Microsoft Update to fail.

This windows update error code means you already have the latest drivers installed onto your computer and you don't really need to upgrade it.

What causes Error 0x80070057

# Windows Update simply has an issue with your "SoftwareDistribution" folder.

# This appears to be an issue with the program Netop which enters a driver entry into the enum\root\unknown key in the registry.

# You have old versions of OKI drivers installed.


To resolve this error, use one of the following methods:

Resolution Suggestion One:

# Try renaming the SoftwareDistribution folder:


Click Start, Choose Run.

In the Run box, type: services.msc

Click OK.

Right-click the Automatic Updates service.

Click Stop.

Stopping the service will take a moment.

Now rename the "SoftwareDistribution" folder:

a) Click Start, click Run, type

%systemroot%

...and then click OK.

b) Right-click the SoftwareDistribution folder, and then click Rename.

c) Type SoftwareDistribution.old and then press ENTER to rename this folder.


Now click Start, and choose Run.

In the Run box, type: services.msc

Click OK.

Right-click the Automatic Updates service.

Click Start.

NB - You will lose your update download history but this is not that important compared to not being anle to download the updates!

Now Try WU website again.


Resolution Suggestion Two:

# Customer will see error 0x800A138F when scanning for updates, but the Windows Update.log file will show error 0x80070057:

This appears to be an issue with the program Netop which enters a driver entry into the enum\root\unknown key in the registry.

"DriverDate"="Jan 14 2002"
"DriverVer"="7.00 (2002014)"
"MatchingDeviceId"="danware_netop_driver3"

Both the DriverDate and DriverVer are not formatted properly
