Restoring Taskbar Icon size? Dword not working

[OutsideOctaves]

I've tried the dword TaskbarSi setting set to all three 0, 1, and 2... and that's not working. I used This Is Win11 to change the setting, and this doesn't work. (was following a youtube tutorial... didn't untick this particular settings change and now I can not figure how to reverse this). Any ideas? (Yes I restarted Explorer, multiple times now, I am using 1 currently in the TaskbarSi Dword file)

I found the problem, essentially there was another folder in regedit that was very similar to the one I had to be in, and I was in this wrong folder (followed youtube guide, oi... gotta love it when they get something wrong). I found the exact folder, so case in point: always be exacting in what folder(s) you're in when using RegEdit lol. (something I thought I already knew well enough, oi)
