Checking for the latest version of windows updating software
You could also change the same registry key or set Windows 8 to only install updates when you choose to work around this, just on Windows 7.If you’re updating manually, you can click the “updates are available” text in the Windows Update window and see what updates will be applied.On Windows 7 and previous versions of Windows, Windows will start to nag you after installing most updates.It will pop up and inform you that it’s restarting your computer in fifteen minutes unless you postpone the shutdown.
If you don’t reboot in three days after installing updates, the nagging and automatic reboots will start.
The “automatically download updates” option gives you a good combination of automation and manual control, automatically downloading updates and letting you choose when to go through the reboot process.
Whatever you do, don’t disable Windows Update completely — it’s important to have the latest updates to stay secure online.
If you step away from your computer or leave it running overnight, Windows may automatically restart your computer, halting whatever it was doing.
To fix this, you can change the value of the No Auto Reboot With Logged On Users registry key, forcing Windows to not reboot if a user is logged in.
