Hi macky1234, If you think that the problem might be in Windows, an easy way to reset everything is by using: MalwareBytes AdwCleaner https://www.malwarebytes.com/adwcleaner/ Besides being a recommended adware removal tool, there are Basic Repairs in the settings which restore networking settings that malware may have wreaked havoc on. (Some Windows Updates are certainly considered to be malware!) The image shows the default settings. I turn on everything, run a scan and select the Run Basic Repairs button. You need to restart your computer to complete the repairs.
