No need to (and it probably won't work) to enable dotnetfx35 twice. Just run W10UI with the current updates: https://forums.mydigitallife.net/th...-17763-xxx-pc-rs5.77945/page-216#post-1490183
Every month have 4 window to release patch. B = Second Tuesday of this month. C = Third D = Fourth and emergency window called out of band can release patch any day.
The B Release update on Patch Tuesday are the only one that's are mandatory because they contain new security fixes, the C and D releases are optional as the new software fixes they contain are not urgent. You'll be getting them next Patch Tuesday anyway. IMO it's always best to wait before installing C and D updated unless your are affected by the issues they "fix", they are considered "Beta" or "Early Access" for people installing them and those can bring up new issues.
so i did install the LPs on the clean MDL iso, then I added the updates+.net 3.5 but the LPs are not shown in windows settings. All I see about those LPs is when I launch the iso and it asks me to choose the language. Once windows is isntalled, all I have is the default language and zero added language... I checked the installation of .net 3.5 in the features and it is not checked. So i guess i do not have .net 3.5 However THe installed windows is indeed up to date, that's good.
Time to see if this adds another 5% perf. drop for my 8700K like the previous one. Nothing new for Coffee Lake I see. Hoped Intel released updated mc for its last CacheOut thing.
On a system that doesn't have installed the Intel microcode updates (when it comes to the software part) and using an old BIOS that the microcode is not updated also, will the CPU continue to run in full as before or the CUs also have effect on this, besides the BIOS/MCU combination?
Afaik, there only a slow down when the microcode updates are installed and set to fix on and/or the bios is patched.
Have asked that because at the beginning of all these (01-2018) there where problems with the CUs and with many antivirus programs and there where no MCUs at the moment and everybody (Tech sites e.t.c) where already measuring cpu/system slowdowns. On Win7/8 i guess some patches are in their CUs and that this does not apply on Win10.
Pretty sure the first Meltdown/Spectre patches will have an effect by themselves, how significant, it depends on the CPU. You should go and disable them in the registry if you want to preserve all the initial performance. Mind you, I only took an actual performance hit (about 1-5% depending on test/benchmark) for my 8700K with the C6/CA microcodes from a few months ago. So if you have a Coffee Lake it's likely that you can use all mitigations without losing much performance. The problem is for older CPUs.
If MCUs are not available (or wanted), keeping the Meltdown/Spectre mitigations ON is useless most slowdowns affect 32-bit Windows
