Thanks. Did as you suggested and worked instantly. My question is tho does anyone know why this is happening?

WenchxHunter No clue. The upgrade must use generic Registry values that don't work for all. But this little tool has always fixed my problem. It simply tweaks the registry values for better throughput. Wish I had a better reason as I'm just guessing. But this always seems to happen with upgrades and some updates. Glad the fix worked for you.

  In my case, I simply disabled Citrix Virtual Adapter. It seems this virtual device did not like the upgrade from Windows 10.

The Reason for the Speed Problem is very Easy. On the Device Manager, select the Network Interface, right click and then on preferences. Click on Extended. Seach for Speed & Dublex. On my device the 2,5Gbs entry was selected. Go to 1.0 GBS FullDublex and the Problem is solved!!!

  SidEwigk THIS WORKED, like a charm!! New PC build was fine yesterday, this morning it was very slow. Changing the adapter to 1Gps Full Duplex fixed it. Thank You!
