Does Resetting Windows 10 Make It Faster?

The short term answer to that question is yes. A factory reset will temporarily make your laptop run faster. Though after some time once you start loading up files and applications it could return to the same sluggish speed as before.

Does factory reset improve performance?

Performing a factory data reset helps in completely erasing everything on the device and restoring all the settings and data back to its default. Doing this does help the device perform a tad better than when it was loaded with apps and software which you might have installed over a period of time.

Is it worth resetting Windows 10?

Yes, it is a good idea to reset Windows 10 if you can, preferably every six months, when possible. Most users only resort to a Windows reset if they are having problems with their PC. However, tons of data get stored over time, some with your intervention but most without it.
