Hello, I updated my windows 10 to 2004. I cannot login to my computer after updating. Windows 10 keeps signing me out immediately after logging in. How can I take action against this problem? ps: I tried to login in safe mode. I can login there successfully.

I'm having a similar issue. My Start Button (and everything that works off it, which includes the action centre) stops working after this is installed. I've tested and it's definitely KB4571756 because uninstalling it fixes the problem. It also caused ASUS Armory Crate to fall over (error in cdp.dll - says the file is incompatible with windows); I hoped uninstalling that would solve the issue, but it didn't.

WinnDoz, Service Stack updates are automatically applied before the cumulative updates. There is nothing you have to do to install them. It is unfortunate that these updates are causing so many issues. It seems now we are spending more time trying to protect our systems from updates than using our systems. Backing up to an external hard drive is the best thing you can do. Having a cloud backup is good as well. Having at least two copies of your files is wise. A good backup program that you run at least prior to the updates being released (normally on the 2nd Tuesday of the month) is now almost essential. Macrium Reflect is a highly recommended backup program which will allow you to backup your entire system. They have a "free" version. Good luck and hang in there. JohnD
