W7 very slow copying to USB

Recently I got a WD Elements 160 Gb external HDD. Right on time because my RUVO MC was almost full so I needed to move few movies out of it. I connected the USB HDD and start moving the first 1.5 Gb movie. Something was wrong, a process that should not have taking more than few minutes now was taking more than 20 minutes. I did some research online and for my surprise found many users reporting the same issue since the release of Windows 7. There is not any fix from Microsoft so far but the good news is that I found following the above link in the wonderful Technet forum the solution.

How to fix this issue:

Disable Superfetch and Remote Differential Compression.

Superfetch can be disabled by;
Going to start > right clicking Computer > Click Manage > Choose Services and Applications > Services
Find "Superfetch" in the list, and right click > Properties > Change "Startup Type" to "Disabled"
Then Hit "Stop" then "Apply"

Remote Differential Compression can be disabled by:
Going to Start: Control Panel > All Control Panel Items > Programs and Features > "Turn Windows Features on or Off"
Uncheck Remote Differential Compression and Click OK.

Restart the computer after these changes.
