I've noticed similar issues after the same update. One thing that helped me was checking for updates specifically for drivers and other software components, which might not automatically update with the OS. Also, consider running a system file check by entering sfc /scannow in the command prompt to repair potential corrupted files. This improved my system's performance noticeably. It's always superior to ensure that your hardware specs are also up to date with Windows 10 requirements for optimal performance. Hope this helps!
