Windows Activation guide
• First, we need to get rid of that ugly watermark. Just edit PaintDesktopVersion's value located at "HKEY_CURRENT_USER\Control Panel\Desktop" using regedit. Set it to 0
• We still can't change our theme and wallpaper which sucks. Fortunately, we can do change these the same way we did when we got rid of that pesky watermark
• To enable dark mode, just browse to "Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize " and change these two entries' value to 0. As soon as you change them, dark mode will be activated! (how amazing)
• Changing your wallpaper is even easier. Just download the wallpaper of your choice and....
• Sadly, we still have that ugly blue accent color next to our amazing new wallpaper. That's also fixable using a quick registry hack. Just browse to "Computer\HKEY_CURRENT_USER\Control Panel\Desktop", create a new DWORD, call it AutoColorization, and set it to 1.
• You'd have to restart explorer for the previous tweak. Next, we might want to color.
• Now, you might want to color your taskbar. That's yet another registry hack. Browse back to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize " and modify ColorPrevalence
• This can take a few values. They are the following: 1 = color start, taskbar and action center 2 = color taskbar only
• Do you want a colored title bar? Change the ColorPrevalence value in "Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\DWM" to 1 and here you go.
• Literally the only locked down options in Windows can be easily modified using regedit, a built in Windows tool
