Outdated drivers can cause performance issues. Go to Settings > Windows Update > Advanced options > Optional updates to check for driver updates.

Use the built-in Storage Sense feature: Settings > System > Storage > Turn on Storage Sense.
Delete temporary files or move large files to an external drive.
