Re: pgAdmin4 v9.2 causes unexpected Windows Server reboot during silent installation

Hi, Aditya Toshniwal

Thank you for your reply.

We understand that the pgAdmin installer itself does not explicitly request a system restart.
However, we experienced automatic reboots on several Windows Server 2022 systems immediately after installing pgAdmin 4
v9.2(pgadmin4-9.2-x64.exe) in silent mode. 

Event Viewer shows Event ID 1074 (process: winlogon.exe, user: NT AUTHORITY\SYSTEM).

We are wondering if, during the installation,
the installer might trigger the installation or update of dependent modules (such as Visual C++ Redistributables or
Pythonruntime),  
which in turn cause Windows to request a system restart.

Could you please confirm whether this behavior is expected
or if there are any known dependencies that may require a restart on first installation?

Thank you,

Shumpei

Dear pgAdmin Support Team,

We are using Windows Server 2022 and encountered unexpected system reboots right after installing pgAdmin4 v9.2
(pgadmin4-9.2-x64.exe)in silent mode. 

Event Viewer shows Event ID 1074 (winlogon.exe, user: NT AUTHORITY\SYSTEM). 
Could you please confirm if the installer intentionally triggers system reboot or if there is a known issue related to
thisversion? 

Thank you for your support.
