Every time Windows gets a significant update, the vast majority of existing tweaking utilities become obsolete. For every option that you fine-tuned with one of these tools on Windows 7 or 8, there's a change in the registry or system settings that cause your tweaks to now point to a dead end. This was definitely the case with Windows 10, since there were so many sweeping changes that very few existing options carried over.
But thanks to developer Paras Sidhu from TheWindowsClub, we now have an awesome new customization tool called Ultimate Windows Tweaker 4 that will let us tweak almost any aspect of Windows 10. The tool is quite comprehensive, so I'll guide you through all of the various menus below.
