Because Winecfg run by using Wine, it is impossible to work with it without OCR function, because screen reader compatible with Wine do not exist. So please, which registry keys or other values should I change to set Wine emulation to Windows XP from default Windows 7? I need to test some screen readers which work differently in XP mode than in Windows 7 mode. Including Windows light translingual. it is written in C++ with not many depednecies. So I need to try it. NVDA will never work, because it depend on many Microsoft visual C redistributable and on their registry values. And on UI automation when Windows is Vista or newer. Sure, NVDA can also work differently when operating system is Windows XP. But also in those cases, there are issues with missing oleacc.dll MSAA specific functions.
