Most have had a COA on the back that told me which OS was installed......but as we get into the machines that could have had 32 or 64 bit OS installed I dont know how to find out when I get them back up and ready to reload.......
One machine was a Dell and they had a nice site I could enter the serial # and get system specs........guess what....32 or 64 bit was not mentioned
Today I am working with an Acer That is Vista Home Premium OEM per the COA.......but is is 32 or 64 bit ????
I enter the SN at acer and I get the Name of the person I bought it from and when the warranty ended.......for more information thay want me to pay for a support ticket......
Any advice appreciated.....I have researched this online......but all the answers seem to be for when you have a windows bootable pc
