Samsung N102SP netbook also slowed to glacial operation ...
Windows 10 Home was marginally faster than Windows 7 Starter.
Real speed arrived after installed memory (RAM) increased from 1GB to 2GB (about £17).
Windows 10 was not really usable due to screen driver default to 800x600px instead of the native 1024x600px:-
The problem falls in the business gap between Intel (Graphics Media Accelerator 3600 Series), Samsung and Microsoft.
The solution I chose is linux [Lubuntu 16.04 Xenial Xerus] ... <fastest>!
