Experienced an issue with one machine with continuous corruption problems After the 3rd attempt I discovered that even with a Clean Install of Win 10 I get unrepairable errors - Sorry...
Final version of Malwarebytes 3.0, the next generation antivirus replacement has been officially released and available for download.
After many restarts I ended up getting the updates on the system without any more errors. For now Windows 7 remains on it, but I am very close now to going to a 32-bit version of The LXLE Desktop Linux distro.
Disclaimer: NOT yet running Win10 & NOT Malwarebytes staff - just a long-time MBAM home user and forum volunteer (@daledoc1).
Without a bit more information, it's hard to say for sure.
