What should I do if the Internet speed is very slow after installing the official version of win10 on the desktop?

After upgrading win10, many people find that the Internet is slowing down. This may be a network card driver problem, or it may be a problem with QOS settings. 1. First check with software (drive XX) whether your network card is up to date or the most stable version, in general, no problem, but just in case
2, WIN + R, enter gpedit.msc, enter the group policy management


3, found on the left & nbsp; windows settings & rdquo;, left click, and then found on the right "based on the strategy of Qos", right-click "based on the strategy of Qos", select "advanced Qos settings", set the picture, basically no problem
