34 very quick "How To" titles.
All of these can be accessed from the same page from the link below.
None of which should take more than a couple of minutes.
Some of the "How to's" involve entering and adjusting the registry, so be warned, "Backup the registry before altering anything"
(*)Any that involve altering the BIOS should only be performed by a PC competent person, or irrecoverable damage can result if not done correctly.
(x)Some of the "How to's" also involve installing a third part program which a link may not be supplied, so just copy and paste the suggested program title into your search bar and search for the program.

None of the above articles belong to me or have been formatted by me, all thanks and gratitude to the originator/s.
Although I have slightly changed some of the titles for ease of readability.
"Personally I would not bother with any of the adverts/programs that appear on most, or all of the pages referring to cleaning up the PC" but the choice is yours.
edit: minor typo & new text added.
