Good evening everyone. The last week has been a terrible one as my pc suddenly lags, slows down drastically and won't respond to commands. Even turning it off is a struggle. I've had to force shut down.

Any solution will be live saving at this point. Thank you

Check if you have pending or failed windows updates.

Will do. Thank you

Press window button, then press ctrl R, press ok, press ctrl A, final press Shift+Del.

This will clear off junk and cache file choking the breathe of your system. You will give your system more memory to run smoothly.

After you finish the first method, search for "disk cleanup" from your system, click on the icon to open disk cleanup dialog box, press ok, if you partition your disk, choose C program and press ok, it will take a while or some minute to finish, after that it will bring out a dialogue box, click on every box and press delete.

Your system will run like new.
