To save the configuration as draft, click Save as Draft.

 

Note: Patch Uninstallation is currently not supported for Mac Computers

 

Creating a configuration from All Patches View

If you are trying to create a configuration from Detailed View under All Patches, then the below mentioned scenarios will come into effect. Detailed view will list every missing patch against every single computer in a separate row, which means if a single patch is missing in 5 computers, 5 rows will be listed.  
when y
ou have chosen to deploy more than one patch for more than one computer as mentioned below, then you might end up in deploying the patches to the computers which you never intended to deploy.

Creating a configuration based on the above selection will work as follows:

Selected Patches:  Patch 1, Patch 2  and Patch 3.

Defined Target : Computer 1, Computer 2,  and Computer 3.

Result of this Deployment:

Patch ID Included Target

Intended target

Missing Patch

Will be deployed
Patch 1 Computer 3

No

No

Yes

Will not be deployed
Patch 2 Computer 1

No

Yes

Yes

Will be deployed
Patch 2 Computer 2

Yes

Will not be deployed
patch 3 Computer 1

No

No

Yes

Will not be deployed
Patch 3 Computer 2

No

No

Yes

Will not be deployed
Patch 3 Computer 3

Yes

Yes

Yes

Will be deployed

As per the above mentioned table, the configuration will be deployed across to all the computers to which the patch is applicable. Patch 2 is applicable for computer 1,  but you never intended to deploy it, however the deployment will happen on it, since it is a missing patch.

In order to overcome this, it is recommended to deploy multiple patches to single computer or single patch to multiple computers from "Detailed View". If you want to deploy multiple patches for multiple computers, then it is recommended to create multiple configurations or initiate deployment from Missing Patches View.

Note: When a Patch Management task is initiated, Desktop Central agent residing on the client computer scans the computer for the missing patches and downloads only the applicable patches from the Desktop Central server.
If you are managing computers in a remote office using a Distribution Server, then WAN agents will download the applicable patches from the Distribution Server. However the deployed patches will be replicated to the Distribution Server irrespective of whether the patch is applicable for the remote office computers or not.
