I do not know how many of you had the opportunity to install the latest Windows 10, that was (supposedly) launched on July 29 but since not all users gets it immediately, I don't know if I count on that. Searching on the forum did not revealed if it is crashing for others. After I did an upgrade to Win10 from Win7 (not a clean install) and no matter how it is launched, but TCC.exe always crashing. (TCMD stays alive, and could do things like upgrade, but TCC in it will crash.) I can't find any error report, or crash dump to check for the cause of the crash. TCC before crash, prints the Windows version, and it reports version 6.3.10240. CMD reports 10.0.10240. WinVer reports it like 10.0 Build: 10240. I read in another thread, that version differences was a change in the API, as a backward compatibility feature perhaps?
