--- Comment #10 from Gijs Vermeulen gijsvrm@gmail.com --- (In reply to Dmitry Timoshkov from comment #7)
Probably I should also note, that this commit breaks for instance 'winetricks vcrun2015' because winetricks removes c:\windows\system32\ucrtbase.dll before running the installer, which also completely obliterates the whole Wine prefix, leading to inability to run anything from it. The only "cure" is to remove ntdll.dll pretending that the prefix is "new", however after that the prefix won't update itself, and ntdll.dll is not gets re-created.
Just as an aside, I worked around this by manually extracting ucrtbase from the installer instead of removing it. [1]
