COS Updates
The COS is enabled for automatic critical updates only.
If necessary, you can change the COS update settings. We recommend that you
update the COS according to your organizational IT policies.
Install Software Application from External Network
If you must install software on the COS from an external network, you can
experience an issue during the installation process. That is, a dialog box can
unexpectedly disappear.
This is an example of how the issue can occur.
1. Access the remote network via the X1 port.
2. Browse to an executable file and double-click it.
The Open File - Security Warning dialog box appears.
3. Click Run.
The User Account Control dialog box appears.
4. Click Yes.
The Windows Security dialog box appears that requires you to enter
your network credentials. When you click the dialog box, it disappears.
5. Click ALT + tab and the Windows Security dialog box reappears.
6. Enter your credentials and the installation process proceeds as expected.
TIP This step is one method to get the dialog box to reappear. It is a potential
workaround.
