How to Delete History updates with Vista

I want to delete the failed and cancelled list, I would like to
delete them and leave the list of successful updates. Is this possible?
Thanks.

It may happen that the list of historical updates increase with several important updates and optional, and you want to cancel same. Simply delete the file edb.log in the folder Windows \ SoftwareDistribution \ DataStore \ Logs.

This file is regularly used by automatic updates of Windows, delete it will be impossible, even with software like Unlocker, as this service is loaded into memory. Please note that once the file is deleted cannot be recovered.

Below is a tips of how to uninstall temporarily:


Go to menu Start> All Programs> Accessories.
Right-click on the "command prompt" and select “Run as Administrator”.

Copy/paste the below command:
net stop wuauserv
And select OK.


Wait until confirmation that the service is stopped.


To delete the file, copy the following command in the command prompt:
del %systemroot%\SoftwareDistribution\DataStore\Logs\edb.log

You can use a notepad for this .

Go to the menu Start> All Programs> Accessories> Notepad

Copy/Paste the following in the notepad:

CD \
net stop wuauserv
del% systemroot% \ SoftwareDistribution \ DataStore \ Logs \ edb.log
net start wuauserv

Go to the File menu > Save.
Change the file type "All Files."
Give the file a name that ends with .Bat
Confirm and Close.

To run this batch file, you must right-click on the file and select “Run as administrator” which will remove the history update.

Thank you for reply i will try and post the result here .

Try it by deleting manually.

The service will relaunch in automatic mode at the next reboot, or you can restart with this command:

net start wuauserv

This will not uninstall the updates installed. To uninstall an update, go to “Programs and Features" and click on “Show updates installed”.

I am confused... will deleting the edb.log file delete all update history or only the duplicate update history?

There is no way you can delete update history (Selected) entries.

If you want to clear the windows update history, Navigate to "C:\WINDOWS\SoftwareDistribution\DataStore" Delete "DataStore.edb".

Before you delete "DataStore.edb" you should stop Windows update service and BITS service.
