    Thanks!
    [Edit - removed the rest of my response - I mis-read MS Toolkit as MSMG Toolkit!]

    Nowhere it informs me about the amount of loss of performance (which i don't experience), it's just based on overall assumptions.

    You're right! GHACKS said that the tool didn't do an actual performance test.
    For some, even the idea of the possibility of a drop in performance can make them loose sleep at night. If you're one of those people, than this tool might help you get a good nights sleep!

    I am not so sure that it is even worth patching for Spectre, and Meltdown. This appears to be way way overblown. I am not concerned about it at all. I mean, how long have we been running unpatched sysytems without the least bit of trouble?

    Yes, we have been running unpatched systems, and now it's public and proven meltdown is easily exploited, spectre not so. But the "tool" only informs me about stuff i already knew, when the kernel patches of jan. 3. 2018 are applied, meltdown is excluded (combined with the browser updates), it can cause a slightly decrease in performance, which i didn't experience.

    I haven't looked into this whole thing enough yet, but from looking at the GHACKS article, it seems like the one solution is as easy as applying or removing a simple REG patch. It seems all sort-of 'half-measures'. The other half of the 'solution' seems to involve a BIOS change. Most ...well ... none(!) of my machines are likely to ever see a new BIOS. They're too old!

    The regkey probably will be the QualityCompat key, it's needed to get windows to install the jan. 3. 2018 patches, the used AV should set it.

    Nope. He refers to this one:
    Code:
    reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
    
    reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
    
    This revokes the fixes against Meltdown.

    Shall I copy/paste those lines in a .BAT file?

    As you like. They can also be used directly in CMD prompt.

    3 = disable both
    2 = disable meltdown (VA Shadow)
    1 = disable spectre (BTI)
    0 = enable both

    FeatureSettingsOverrideMask is always 3

    Hmm, I ran the batch file as admin but it didn't add the values in the registry. When I manually copy/pasted them in command prompt though it did

    This is the code I put in the .BAT file and I ran it as admin (my UAC is disabled though if that matters)

    Code:
    reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
    
    reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

    Lemme try enabling UAC then see if the batch file works.

    Edit: Nope, enabling UAC and running the BAT file doesn't work

    That is because quotation marks were left out. Try this:
    Code:
    Reg.exe add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v "FeatureSettingsOverride" /t REG_DWORD /d "3" /f
    Reg.exe add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v "FeatureSettingsOverrideMask" /t REG_DWORD /d "3" /f
