What is the least Memory to run win7 32 Bit?
And what is the Least to run Win7 64 Bit?
I gather you are trying to find out how much RAM is required to pro-efficiently run a Windows 7 OS-based machine. In response to this, my terminologies rely on the make and speed of the Central Processing Unit(CPU) plus the upgradability of the main-board of the specific machine or rather PC/Laptop. Based on my electronic profiles I would say:
Windows 7 32-Bit running on an Intel family CPU ------> 12GB Ram of Memory is enough
Upgradability allowance-------> 16GB
Windows 7 64-Bit running on an family CPU ------> 8GB Ram of Memory is enough
Upgradability allowance-------> Dependance on choice
