Confluence Upgrade in Windows should not override logon account for the existing installed service

Confluence is running as a service with a domain account. While using self-signed certs for active directory server, which java needs to import after the "upgrade".

Currently after an upgrade reconfiguration of the service to use the appropriate account for the service is required.

Considering the frequency that updates are released, its would be useful that Confluence service need not be overridden with default system/network account rather allow the existing service to run with the same domain account.
