My laptop is lagging very badly?

Moin, since 2 days my laptop has lagged very badly, especially when I open an app! I've restarted it several times, but it doesn't work!

Maybe this picture will help, that's my laptop.

Reset Windows or install ssd

More information would be helpful, such as technical data, what kind of hard drive. How old. Has Windows ever been reinstalled? Maybe dusty inside and therefore slow? If it gets too hot, it slows down and slows down accordingly. Hard drive too full, too much garbage?

I don't know that well, I just deleted all garbage data that would be unnecessary, it is still very lagging

Have you ever done a disk cleanup?

Deactivating unnecessary program starts in the task manager under Autostart can also help

Moin my father found out why ea is so lagging, he said there are more than 90 other companies working for some reason, but he wants to break off the nivht because he is afraid that he will stop a company by mistake, which is very important do you have any tips?

A screenshot of the task manager and the running processes could help.

I think I'll do it tomorrow, have to go to sleep right away
