[#ZBX-22865] zabbix_agent2 on windows UserParameter: cannot run executable found relative to current directory

Steps to reproduce:

add to configuration file

UserParameter=zaza[*],powershell write-host "PREVED $1"

Result:

# zabbix_get -s 10.205.255.213 -k 'zaza[MEDVED]'
ZBX_NOTSUPPORTED: Cannot execute command: exec: "cmd": cannot run executable found relative to current directory

Expected:

# zabbix_get -s 10.205.255.213 -k 'zaza[MEDVED]'
PREVED MEDVED

If I start agent2 in foreground(at console) - problem not exists(I get valid responce). Problem exists only when agent2 installed and started as a windows service.

Testing on different agent2 versions with the same configfile on this host. Problem was found at agent2 6.0.13 version and newer:

# zabbix_get -s 10.205.255.213 -k 'zaza[MEDVED]' ; zabbix_get -s 10.205.255.213 -k 'agent.version'
PREVED MEDVED
6.0.0
# zabbix_get -s 10.205.255.213 -k 'zaza[MEDVED]' ; zabbix_get -s 10.205.255.213 -k 'agent.version'
PREVED MEDVED
6.0.9
# zabbix_get -s 10.205.255.213 -k 'zaza[MEDVED]' ; zabbix_get -s 10.205.255.213 -k 'agent.version'
