Microsoft fixes system slowing down and freezing problem in Windows 10 v2004/20H2

1 min read

If you have upgraded Windows 10 v2004/20H2, you may find many problems that seriously affect your use after installing the cumulative update recently.

For example, after installing the latest cumulative update in Windows 10 20H1, some applications take a long time to open and are easy to freeze.

What more users have encountered is that the operating speed of the system drops significantly after installing the cumulative update, and opening multiple applications may cause the system to freeze.

Although there are many users who have encountered this problem, Microsoft has not issued a support announcement for these problems. Fortunately, Microsoft mentioned this problem in the beta update.


According to Microsoft’s explanation, this problem is mainly caused by the locking of the TCP/IP protocol driver. This protocol is mainly used for network connections, so it is very important for the system.

The driver may have some abnormal behaviors after installing the update, including the obvious degradation of system performance encountered by some users.

Microsoft fixed this issue in the beta update KB4580364, which is currently not directly pushed to all stable channel users. Of course, if you also encounter this problem, don’t worry, because the stable version update will be released at night this Tuesday.
