Experiencing performance issues with Windows 10 version 20H2 isn't uncommon, and there are several ways to address this. Start by checking for any pending updates, as Microsoft often releases patches that can improve stability and performance. You can do this by going to Settings > Update & Security > Windows Update.
Another helpful step is to perform a disk cleanup. Use the Disk Cleanup tool to remove temporary files and system cache that can slow down your system over time. You might also want to review your startup programs. Disabling unnecessary programs from starting with Windows can significantly improve boot times and overall performance. This can be managed in the Task Manager under the 'Startup' tab.
If the freezes persist, consider running system diagnostics or using the built-in troubleshooter under Settings > Update & Security > Troubleshoot. Checking the health of your hard drive and ensuring no hardware issues can also be beneficial.
As for optimizations, ensuring that your drivers are up to date, particularly graphics and chipset drivers, can also help. If the system still underperforms, you might contemplate a fresh install after backing up necessary data, or look into increasing RAM if your hardware permits.
For system features, 20H2 included some tweaks and enhancements, but none that should inherently cause significant slowdowns. However, if you've got Live Tiles, try turning them off to see if it helps, since they can sometimes use additional resources.
Keep an eye on forums and Microsoft's official support pages for updates on any known issues with 20H2. If you're ready to explore new features or significant updates, consider upgrading to a newer version, as newer builds often have performance and security improvements.
