so cool, can i restore the defualt theme if i need?

just run y_reset_accent_color_variables.reg
you can also save your current theme in settings and then re-apply it (or one of the default ones)

Thanks for the Black Theme. Works like a charm on my OLED Laptop screen, and helps to save battery. Default windows "dark", are not real dark.

loving this theme so far! you mentioned "removed borders" in one of the updates, but the borders look the same to me :\ is there a way to remove the annoying 1px border that is around all windows on 11? ss for reference:

Love the theme, great work. I was wondering if the folders could be black like the start menu? Thanks in advance !

I installed the black theme on my windows 10. Now i had no idea it would make it impossible to add a lockscreen image. So i tried using the undo reg and it did not revert lockscreen changes and the restriction in settings. I love how it looks but not being able to revert changes makes me feel uneasy. Any way you can create a reg file that will allow me to set a custom lockscreen image again please?

can u also post default reg file ... if i get things wrong i will be able to revert it

@techgamers2
y_reset_accent_color_variables.reg will reset the changes
I checked it again and it works, but added those solid / no-lockscreen too (preset themes do not enforce them)
all you need after a logoff / restart is to change your theme in settings

another issue is github being dumb and using LF unix line endings for windows files - but now when you use download zip button the correct CRLF line endings will be inforced

I tried both pitch black and pitch black solid, neither gives me a black taskbar on Win11 22H2 (22621.525). Anything I am doing wrong?

@bindi, it's translucent.
Never came up, but you need a background that is black behind it.
You would lose the ability to differentiate the active taskbar button otherwise
But that's more impactful in Windows 10.
For 11, just go ahead and turn Transparency effects off in Personalize - Color.

Solid version should give you a black taskbar. You probably haven't restarted your PC after applying the reg - it toggles DWM values, so killing explorer / logging off is not enough, must restart.

Yup, OLED enjoyer here. Pitch black.

This is already done.

must restart.

Restarted as well.

I'm a local user (with access to the administrator account), does this matter? No UAC prompts when running the .reg file.
My lock screen is also not changed to black.

Edit: looking at "Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Accent" I can see that the values do not correspond to what the .reg file has, so they are not being applied at all..

Final edit: I had to make myself an admin again, run regedit.exe as my admin account, import the reg file, and voilà. Double clicking the reg file directly just gave an error about access to the registry, even when I was a local admin. (a relog could have fixed this probably)
Running regedit.exe as "the other" administrator would make HKCU their, and not mine.

I also unblocked the file (downloaded from internet checkbox thingy in properties) for good measure.

Taskbar / start menu are now pitch black. I also had to run the no lockscreen .reg to get rid of the picture showing.

Now things are as they were in my Win 10 build before. Thanks, and sorry for the noise.

Yeah, the perks of running a limited user account - when you import a reg it does not prompt you but silently redirects other hives, so you can't tell at a glance why stuff does not work.

But that's how all people should run; it's 100% microsoft's fault for "cultivating" all software elevating forcing users to login as admin to reduce annoyances. And something as basic as the desktop colors are no longer configurable just via a text file theme / hkcu alone in 10 & 11.

A script would be more suitable than a simple reg file, since the changes required are across the current user, local machine and the system account hives!
