These are windows processes, the operating system that you use takes up resources in the background before you even start using any other program. If you have an older computer or just generally one without much power windows will take up a lot of its resources on its own.
However you say it has only been lagging 'recently' so I will help you do a little bit of investigation before we come to a conclusion.
1. What are your system specs?
2. Have you tried running antivirus software? I recommend malwarebytes, you may have malware on your system that is causing this spike in usage.
its a fault on my part, i had meant to start the scan when this all started but i put it off because my computer kept restarting for scans and other possible fixes, pretty sure itll be solved after the scan is done
