Windows 10: Internet download speed suddenly reduced after switching SSD's.

My old SSD had corrupted so I had to switch it out and reinstall everything. I installed all of my drivers and updated my network adapters and it still hasn't fixed anything. It's very aggravating as my D/L speed only goes up to 25mbps. I've purchased a separate USB WI-FI dongle, that didn't work. I purchased a WI-FI extender, that also didn't work. Is there any reason that, after switching SSD's, my network download speed significantly dropped? And is there anyway I can fix this?

Mouse cursor speed suddenly reduced

After this week's Windows 10 update, my mouse cursor speed was suddenly reduced. I went into Settings, and increased the speed from 10 to 20, and now it appears to be working normally. But why the change? And at some point in the future, will my mouse begin working super-fast, requiring me to reduce the speed setting back to 10?

 

Slow download speed after creating Hyper-V External Virtual Switch

Hello.
After buying a new PC (its specs are on my profile), enabling Hyper-V and creating a new External Virtual Switch, I notice that the download speed drops dramatically. My internet conneciton is 1Gbps down and 200Mbps up.

Without External Virtual Switch:

• Speedtest (I get 944 Mbps download, and 214 Mbps upload) --> Speedtest.net by Ookla - My Results
• CPU usage while on Speedtest (no core is maxed out):

• Iperf with a host on the same LAN (upload 911Mbps, download 777Mbps):

• Lan Speed test (746 Mbps upload and 716 Mbps download):

With External Virtual Switch:

• Speedtest result (I get 378 Mbps download and 212 Mbps upload) --> Speedtest.net by Ookla - My Results

• CPU usage while on Speedtest (notice the first core is fully maxed out):

• Lan Speed Test (742 Mbps upload and 596Mbps download):

• Iperf with a host on the same LAN (upload 861 Mbps, download 583 Mbps):

• CPU usage while on Iperf (download) - Notice, once again, Core 1 fully maxed out​:

Conclusion

When the External Virtual Switch is enabled, I assume the download speed is lower due to the fact one CPU core is being maxed out, my question is why? Why isn't the load spread throughout the cores?
Is anyone experiencing a similar issue?

Regards.

 

Slow download speed after creating Hyper-V External Virtual Switch

Have you set the number of cores to 8 in hyer-v settings (virtual processor). No idea otherwise.
