How should I open the properties window?

[ilyfairy]

I disabled taskbar changes in advanced settings, and then I can't open properties.

to run the explorer patcher properties application, run this from the run menu:
C:\Windows\System32\rundll32.exe "C:\Program Files\ExplorerPatcher\ExplorerPatcher.amd64.dll",ZZGUI

Then go to advanced and make sure the option Do not change the taskbar context menu (e.g. do not display the "Properties" is not enabled. Then you can right click on the taskbar and you should see the Properties option.
