1. Login to the SEPM console
2. Go to the Admin > Client install packages
3. Define your Client Install Settings to "Maintain all previous logs, policies, and client-server communication settings".
4. Export a client package with your client install settings created in point 3 (to keep previous settings and policies), select "Export a managed client" without selecting a client group
This will export a client install package with default settings and will retain the previous configurations during the installation.
Note: If any corruption of data/client installation occurs in the machine, when the installation attempts to fix itself, it may require data that is in the installation package and this may cause the client to receive the default policies.
