Steps to reproduce:

1. We use a custom Name for multiple Agents
2. HostnameItem=system.run[echo InternalCompany_%computername%]

Result:
Starting of Agent ends in Error:

ERROR: Failed to handle Windows service: cannot process configuration: cannot get system hostname using "system.run[echo InternalCompany_%computername%]" item specified by "HostnameItem" configuration parameter: Timeout occurred while gathering data.
Expected:
zabbix_agent2 [10724]: 'Zabbix Agent 2 [InternalCompany_Servername]' started successfully

After downgrade to Version 7.2.5 everything works normal
