Check Windows Update settings
Windows 7 provides regular updates to fix bugs and patch security vulnerabilities, ensuring a safe and enjoyable computing experience. While Microsoft ended support for Windows 7 in January 2020, you can still check for and install any outstanding updates released before this date. Here's how to check and manage your Windows Update settings:
Checking for Updates
- Click the multicolored Windows 7 Start orb at the bottom-left of your screen.
- Open the Control Panel.

- Click the "Check for updates" button on the main screen. If you don't see the button, click the "Check for updates" link in the left pane.
Managing Update Settings
Windows Update settings control how Windows looks for, receives, and installs updates from Microsoft. You can customize these settings to determine when updates are installed and whether to receive updates for other Microsoft products. Here's how:
- Open the Control Panel.
- Choose "Windows Update" from the System and Security window.
- Select "Change settings" on the left.
- Choose how you want Windows 7 to check for and install important updates. You can set it to install updates automatically, download updates but let you choose which ones to install, or check for updates but let you choose to download and install them.
- If you select automatic updates, specify how often and when you want Windows to install available updates.
- Check the box for "Give me updates for other Microsoft products" if you want Windows Update to handle updates for other Microsoft software you own.
- Check or uncheck the box for "Show me detailed notifications when new Microsoft software is available" depending on your preference for notifications.
- Click "OK" to apply your changes.
It's recommended to keep automatic updates enabled to ensure your system remains secure and up to date. However, you can also choose to disable automatic updates and manually check for updates, although this requires remembering to do so regularly.

Name the task 'Wake Up' and tick the following boxes: ''Run whether user is logged on or not', 'Do not store password', and 'Run with highest privileges'.
Next, go to the ''Conditions' tab and tick 'Wake the computer to run this task'. Then, go to the 'Settings' tab and tick 'Allow task to be run on demand', 'Stop the task if it runs longer than', and set it to 1 hour. Click 'OK'.
To ensure this operation works, you may also need to enable wake timers in Windows. Go to the Control Panel, click on 'Power Options', then 'Change plan settings', and 'Change advanced power settings'.
