Your Windows Virtual Server needs to run Windows Update in order to stay current with the latest security patches and software updates.
Microsoft configures Windows Update, by default, to download the updates only. An administrator would then need to log in and accept the updates, which usually requires a restart of the server to apply the updates. As a best practice for security, eApps configures Windows Update as Automatic by default. The update process will run every Saturday between 1 AM and 4 AM server time, US Eastern time (EDT/EST). However, if you change the server timezone, the updates will run based on the new timezone setting.
In order to minimize bandwidth usage, the exact time the update runs is randomly determined by a script. In most cases, your Virtual Server will be rebooted as part of the update process.
Having Windows Update set to Automatic is a best practice so that your Virtual Server is regularly updated with the latest security patches and software fixes. This helps keeps your Virtual Server secure and reduces the chances of it being compromised or taken hostage by ransomware pirates. The downside is that your server will be rebooted periodically for most updates.
You can change the Windows Update behavior back to the Microsoft default of Download Only, or to be totally Manual. If needed, you can also change the schedule for the Windows Update, including changing how often the update runs. This is done by making a change to Windows Update.
