How to download and install the April 2024 security updates
Security updates are downloaded and installed automatically on non-managed Windows devices by default. Windows users who do not want to wait for this to happen can speed up the process by searching for updates manually in Windows Update or by downloading the updates manually to install them.
Here is how that is done using Windows Update.
- Select Start, type Windows Update and load the Windows Update item that is displayed.
- Select check for updates to run a manual check for updates.
As always, make sure to back up the system before installing any updates. It is a good safety precaution. While Windows does include recovery options, this may fail and it is always a good idea to have a second option available in that case.
