​For the first time in years, Microsoft Windows will demand more memory

That Windows 7 PC you got back in 2009 is powerful enough to handle Microsoft’s latest operating system — but that could change, because Microsoft is increasing its minimum system requirements.The upcoming Windows 10 Anniversary Update will need a minimum of 2GB of memory, according to a Microsoft developer page. That was the minimum memory already required for 64-bit versions of the operating system, but Microsoft previously required only 1GB of memory for the 32-bit version.
