Why did my download speed go down after making these adjustments and what can I do to restore the settings to get speeds back to normal?

I followed the steps from a guide below:

Use Cortana to search for “CMD.”
run cmd

Right-click on “Command Prompt” and click “Run as administrator.”
run command

netsh interface tcp show global 

Look for “Receive Window Auto-Tuning Level” under the results in the Command Prompt window.

auto-tune If it’s set to enabled, it’s turned on, and may be causing your internet issues.

To disable it, run the following command:

netsh int tcp set global autotuninglevel=disabled 

the results should be immediate, although it is recommended to restart your PC and power cycle your network gear just to be safe.

Successful command entered: success 

If that doesn't work for you, you can try to: Press Windows key on your keyboard, then type CMD on search, right-click on the result and choose Run as Admin. Type these following commands to reset your internet/network settings:

netsh int ip reset resetlog.txt ipconfig /flushdns netsh winsock reset Restart your PC and see if the issue is resolved. 

Note, both of these solutions are shots in the dark. You have left us with very little information to try and help you with this issue.

I did this to get better download speed on uPlay as before I was getting 4.8/4.9mb. After doing these things it went down to 2.7/2.8mb.

Can I change stuff back or is there like a setting that I can change to get my 4.8/4.9mb download speed?

The only thing that should have an effect is the auto-tuning. You can set it back to what it was set to before by running

netsh int tcp set global autotuninglevel=normal 

The other command you ran should simply reset your network stack. Rebooting your PC should clear anything that is left.
