Hi, I want to change this key in registry HKU\...\Software\Microsoft\Internet Explorer\Desktop\Components\0\Position because I need to change the size of windows after maximized. I checked using regshot that this key is modified after change the size of the taskbar. This change causes that windows after maximized don't overlap with taskbar. When i modyfied this key the change isn't visible , even if i refresh the desktop. When i log off and log in but the key got overwritten. I tried restar explorer.exe but i didn't help- the key got overwritten. I need to find a way how to refresh this change and what is also important do it without log off. Do you heve any idea ? Sory for my english
