Really(???) I don´t understand! Today, after running SFCFix i received good news, corrupted files were fully corrected by the reinstallation of an APP (HP Print and Scan Doctor V5.6.1), from my printer device.
"sfc /scannow found no violation integrity" - i´ll live SFCFix and CBS logs for further analysis (case study(???) - Window´s a mistery).
I also used a program, from my own risk, that "forced" the uninstallation of previously installed programs and kept "a clean registry" by "cleaning old entry keys" (Wise Program Uninstaller).
Kind regards, hope this case will improve Knowledgment...Thks
