  * To merge a single computer, open its Summary page, and click on "Merge this computer".  You will see a list of computers eligible to be merged with this one, and you can select any or all of them.
  * The "Your computers" page has a link '''Merge computers by name'''.  This feature lets you automatically merge all eligible computers having the same domain name.  This is handy if you run a "computer farm" and periodically reformat all the drives.

+
+In absence of a merge feature at this project, WCG introduced an alternate method called ''host matching'' to recognise previously existing devices to prevent new / duplicate registrations. For that the server compares standard information exchanged during server-client communications being:
+
+ * user name
+ * domain_name
+ * ip_addr (the ip of the client on the local network)
+ * operating system name
+ * processor vendor
+ * memory
+
+The most recent record that matches this critiera (if found) will be re-used. It will cancel any results currently assigned to the client, and then issue new work. This is because a user might be trying to clear out some work that was causing some form of trouble. If any of this information is hidden through for instance setting the <suppress_net_info> flag in the cc_config.xml file suppressing the IP address or domain_name, the method fails and will create a new device registration.
