Windows 10 compatible?

Hello Mark7861, Welcome to the Webroot Community Forum. :D
 
Webroot is always up to date 24/7 from the cloud. So as soon as you download and install Webroot it is up to date and all Webroot Products are compatible with Win 10. See Here. 
 
Please follow the steps below closely in terms of installing WSA on the target system/machine!
 

• Make sure you have a copy of your 20 Character Alphanumeric Keycode! Example: SA69-AAAA-A783-DE78-XXXX
• KEEP the computer online during the install to make sure it works correctly
• Download a Copy Here (Best Buy Subscription PC users click HERE). Let us know if it is the Mac version you need.
• Install with the new installer, entering your Keycode when prompted to do so in the install process
• Let it finish it's install scan
• Reboot 

 
HTH,
Dave 😉

Hi and welcome to the Community @
To add to what Protruckdriver has said I have been using Webroot for quite a while before and after W10 was launched and have never had any incompatibility issues at all so I think you should be able to use it without any problems at all.
