Step 1 Update all Windows software

netsh int tcp set global congestionprovider=ctcp
Step 5 Changing Internet Explorer 9's options
Open Internet Explorer 9 and go to Internet Options and under the Generaltab, go to Browsing History, click Settings and check if Temporary Internet Files are at 250 . If not, change it.
Step 6 Get namebench
Go to the namebench website and choose whichever operating system you have installed, then download and install it.
Chose the browser which you use most often and run it. Once finished, it will provide you a DNS server address (e.g. 18.104.22.168 and 22.214.171.124). This is the Open DNS one, which is pretty fast, but depends on where you live—you could have a faster DNS server address.
To add it, go to Network and Sharing Center. Go to Connections and click on your connection. Then Properties and on Internet Protocol Version 4, click Properties and under DNS Server, type yours in.
