Help! My Dell Inspiron Is Slowing Down

Hey everyone, looking for some advice. Over the last week, my Dell Inspiron has been lagging and slowing down, especially during boot-ups. Here are my specs:
  • Device: Dell Inspiron 7000
  • Processor: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.21 GHz
  • Installed RAM: 16.0 GB (15.8 GB usable)
  • System Type: 64-bit operating system, x64-based processor
  • OS: Windows 11 Pro, Version 22H2, OS build 22621.3007
Any tips on how to speed it back up?

Thanks!
