I quote from an item on the BT Internet's news service:
"According to NetMarketShare, Windows 7 remains the most popular operating system on PC, with 44.81% of the market share in February 2018. WIndows 10 is slowly increasing but still comes in second with 28.19%. "
I do not question the statistics, but does anyone else see the flaw?
You will if you are not so taken in by advertising blurb that you fail to realise what is carefully concealed.
