## Windows
For Windows 10, you must first upgrade any anti-virus software before
upgrading Windows. Failure to do so may make your computer stop working.

To upgrade Windows 10:
> Select the Start button, and then go to Settings > Update & security > Windows Update, and select Check for updates.
Now is a good time to enable automatic updates:
> Select the "Start" button, then select "Settings" > "Update & security" > "Windows Update" > "Advanced options" and then under "Choose how updates are installed", select "Automatic (recommended)".
If you are running Windows 7 or 8, an update is also available.
## macOS
If you already have macOS version 10.13.2 then you are [protected against
Meltdown] [3]. Otherwise, to upgrade macOS:
> Open the App Store app on your Mac. Click "Updates" in the App Store toolbar, then use the "Update" buttons to download and install any updates listed.
Now is a good time to check enable automatic updates:
> Select the Apple menu, then select "System Preferences" > "App Store" > "Automatically check for updates".
Apple plans to soon release an update to Safari browser to provide some
mitigation against Spectre.
## iOS
Apple has said that iOS is affected by Spectre, and an update to
mitigate against most of the new attacks has been released. If you have
iOS version 11.2 or later, [then you are good] [3].
To check for new updates, go to Settings > General > Software Update.
## Android
The bad news is that Android is vulnerable to Spectre and unless you
have a Google-branded phone or run a custom firmware you might not get
an update for months, if ever. However, the consensus among security
researchers at the moment is that the Spectre attack is difficult enough
that there are probably easier ways to compromise an Android device.
Yeah?
There is one thing you can do now to make your Android device more safe
