MAMEWorld Forums - EmuChat - Re: Any Ryzen 3000 series of benchmarks for MAME?

First i thank you, for these infos. At least i was partially right (or wrong, depending on your view). I dont trust any Microsoft infos anymore, simply because i was a person who was affected from a (automatically) update in January 2018. My machine was in a infinite boot-trap after the update and i could not use it for nearly six weeks. No matter if you did a fresh install or trying to repair the old system. The only solution was keeping the machine offline, as you would avoid any Microsoft update. The support was awfully bad, treating many customers with the same problem like shit and even told them that it is the customers fault, which clearly was not the case. They did this, simply by the fact, that they didnt have a machine with the same problem.

I found my solution on a german IT website, which was using 1607 and using ultimate or enterprise editions of Windows 10 , because you can avoid updates (for a month or two). I use this solution till today without any problems.

I did not know this, but if this is true, i can only say that till today there is no ASUS Bios update for my X99 board, that would do a CPU microcode update.

see above. you can trust this... i will not. 1703 and 1709 is just a question of time, when Microsoft will do that in a silent update. AFAIK 1709 is already patched. 1607 is the only version, where Microsoft said, it will not happen.
