Slow internet speeds after installing Hamachi

I've been having this issue for so long now! For some reason, my internet is blazing fast until I install Hamachi. Certain website downloads are affected but others aren't. for instance, downloading ...

    Try this to check the status of Receive Window Auto-Tuning Level

    netsh interface tcp show global

    and if it is disabled, turn it on with

    netsh interface tcp set global autotuninglevel=normal

    This helped me and two mates. The settings need to be run with admin rights cmd  (and shift+ctrl when you run it).

    As far as we understand it you would most likely want Receive-Side Scaling State enabled as well.

    netsh interface tcp set global rss=enabled

    We have not tested Hamachi after changing these settings. Nevertheless, just wanted to share because this problem was making us crazy.

That's weird. In my case, the steam origin had a normal down speed.
I've only experienced a slowdown in megacloud.
At this time, the only way to fix it is to restore the OS on Windows 10 itself.  Sad news
If you only need to delete games and settings apps  Try using a recovery method that only reinstalls os
It will not delete video files and portable file And it will tell you which apps you kindly deleted on your create htlml remove app desktop So just watch and reinstall the apps you deleted I think this is the only way I can tell you.

    Co-worker and I have the exact same story.  Installing Hamachi caps our speed at about 100mpbs.  Uninstalling it does not fix anything.  If we do a complete OS reset, it goes back to normal.  Install Hamachi again and it gets capped.

    LogMeIn support provided no assistance and said it wasn't their software when clearly it is.
