+# Register as a Windows service
+
+## Prerequisites
+
+The following changes are made in C:\gitea\custom\conf\app.ini:
+
+```ini title="app.ini"
+RUN_USER = COMPUTERNAME$
+```
+
+Sets Gitea to run as the local system user.
+
+COMPUTERNAME is whatever the response is from `echo %COMPUTERNAME%` on the command line. If the response is `USER-PC` then `RUN_USER = USER-PC$`
+
+### Use absolute paths
+
+If you use SQLite3, change the `PATH` to include the full path:
+
+```ini title="app.ini"
+[database]
+PATH     = c:/gitea/data/gitea.db
+```
+
+## Register Gitea
+
+To register Gitea as a Windows service, open a command prompt (cmd) as an Administrator,
+then run the following command:
+
+```sh
+sc.exe create gitea start= auto binPath= "\"C:\gitea\gitea.exe\" web --config \"C:\gitea\custom\conf\app.ini\""
+```
+
+Do not forget to replace `C:\gitea` with the correct Gitea directory.
+
+Open "Windows Services", search for the service named "gitea", right-click it and click on
+"Run". If everything is OK, Gitea will be reachable on `http://localhost:3000` (or the port
+that was configured).
+
+### Service startup type
+
+It was observed that on loaded systems during boot Gitea service may fail to start with timeout records in Windows Event Log.
+In that case change startup type to `Automatic-Delayed`. This can be done during service creation, or by running config command
+
+```sh
+sc.exe config gitea start= delayed-auto
+```
+
+### Adding startup dependencies
+
+To add a startup dependency to the Gitea Windows service (eg Mysql, Mariadb), as an Administrator, then run the following command:
+
+```sh
+sc.exe config gitea depend= mariadb
+```
+
+This will ensure that when the Windows machine restarts, the automatic starting of Gitea is postponed until the database is ready and thus mitigate failed startups.
+
+## Unregister Gitea
+
+To unregister Gitea as a Windows service, open a command prompt (cmd) as an Administrator and run:
+
+```sh
+sc.exe delete gitea
+```
