How to empty the folders containing Microsoft updates in Kaspersky Security Center

The article concerns:

• Kaspersky Security Center 14 (version 14.0.0.10902)
• Kaspersky Security Center 13.2 (version 13.2.0.1511)
• Kaspersky Security Center 13.1 (version 13.1.0.8324)
• Kaspersky Security Center 13 (version 13.0.0.11247)
• Kaspersky Security Center 12 (version 12.2.0.4376)
• Kaspersky Security Center 12 (version 12.0.0.7734)
• Kaspersky Security Center 11 (version 11.0.0.1131)

When using Kaspersky Security Center as a WSUS server, the following folders will gradually increase in size:

• C:\ProgramData\KasperskyLab\adminkit\1093\.working\FTServer;
• C:\ProgramData\KasperskyLab\adminkit\1093\.working\wusfiles. 

If you want to clear the folders and free up disk space:

1. Open Kaspersky Security Center.
2. Go to Advanced → Application management → Software updates. 
3. Clear all filters for the update list. The Not installed on devices filter is set to > 0 by default.

4. Press Ctrl+A on the keyboard to select all updates. 
5. In the update shortcut menu click Delete update files. 

The update files will be queued for deletion. Depending on the Administration Server workload, the operation may take several hours. 

The update information will remain available via the Administration Console. Use filters to exclude certain updates from the list. 

Clearing the FTServer and wusfiles folders will only have a temporary effect. The size of the folders will grow as new updates get downloaded.
