x/sys: howto set a autorun registry in windows

[b1gcat]

I write the code, but does not work. it cannot create xxx and no error found.

func SetAutoRun(run bool) error {
	k, err := registry.OpenKey(registry.CURRENT_USER,
		`HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run`,
		registry.QUERY_VALUE|registry.SET_VALUE)
	if err != nil {
		return err
	}
	defer k.Close()
	if run {
		if err := k.SetStringValue("xxx", SysExecPath("xxx.exe")); err != nil {
			return err
		}
	} else {
		k.DeleteValue("xxx")
	}
	return nil
}

another code:

	key, _, err := registry.CreateKey(registry.CURRENT_USER, "HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", registry.ALL_ACCESS)
	if err != nil {
		return err
	}
	defer key.Close()

	if run {
		nkey, _, err := registry.CreateKey(key, "xxx", registry.ALL_ACCESS)
		if err != nil {
			return err
		}
		defer nkey.Close()
		err = nkey.SetStringValue("String", SysExecPath("xxx.exe"))
		if err != nil {
			return err
		}
	} else {
		key.DeleteValue("xxx")
	}

I didn't try running the code, but since you already are opening registry.CURRENT_USER, you can drop HKEY_CURRENT_USER from the path:

registry.OpenKey(registry.CURRENT_USER, `SOFTWARE\Microsoft\Windows\CurrentVersion\Run`, ...)

Just posting for the sake of posterity:

The reason I came across this was that I was trying to create a user-mode service that would run on user login every time.

Here's how I did it, which is working for me presently:
https://git.rootprojects.org/root/serviceman/src/commit/f95897cf308c3e19d6fe4b088547d8290907e384/manager/install_windows.go#L60-L109 (pinned to a specific commit since the line numbers are likely to change as I clean stuff up).

I also needed to do similar for Mac and Linux, and that project is the cross-platform service manager I came up with, suited to my needs - which are more focused on user-mode services than system-level services.
