Personally if you're using windows ten then go to your start menu and right click, look for the windows powershell admin. From there once it's loaded do a SFC /scannow, type it just like that and press enter. The SFC scan will find and fix most issues on your computer or laptop, normally if it finds a issue it can't fix it will give you a walk through on how to fix it. Hope that helps, if any thing it will fix your computer if it's running slow. :)
