4GB will be enough to run both operating systems and have room for applications.
yeah it can use vista or these other Apple MacOS, Microsoft Windows Vista / 2000 / XP
For WindowsXP, 1GB or more. For Windows Vista and Windows 7, 2GB or more, with 4GB+ being optimal.
The amount of RAM is actually dependent upon the instruction set architecture. For instance: Windows 7 Ultimate, Enterprise, and Professional 32bit can only support 4GB of RAM, while the 64bit version can handle 192GB. Operating System | 32bit | 64bit 7 Ultimate | 4GB | 192GB 7 Enterprise | 4GB | 192GB 7 Professional | 4GB | 192GB 7 Home Premium | 4GB | 16GB 7 Home Basic | 4GB | 8GB 7 Starter | 2GB | N/A Vista Ultimate | 4GB | 128GB Vista Enterprise | 4GB | 128GB Vista Professional | 4GB | 128GB Vista Home Premium | 4GB | 16GB Vista Home Basic | 4GB | 8GB Vista Starter | 1GB | N/A XP | 4GB | 128GB XP Starter Edition | 512GB | N/A Hope this helps :D(my formatting messed up, so that explains why it might be an eyesore)
It depends on the version. 32-bit Windows supports up to 4GB of RAM, whereas 64-bit versions support 4GB + of RAM. It is the same with Windows Vista and 7.
No, your laptop does not need 4GB of RAM to run Windows 8. The basic specifications for Windows 8 is 2GB for 64-bit or 1 GB for 32-bit. 4GB would help with the processor but would not be necessary.
win xp only reconises 4gb in the entire motherboard. i recoment going to windows 2003 as it reconises 4gb in ram and 2 gb in GFX hardware. also win vista is a good OS to run off.
it should but you better have a decent video card and about 4GB RAM
You can only install 64 bit Windows Vista on a machine with 4GB ram. If you have enough ram then you need to do a clean install. To do this boot up your machine with the 64 bit Vista CD. Then follow the on screen instructions.
Vista x86 supports 3.8GB. It means that 4 GB it's maximum you can install. If you compare 2GB installed with 4GB, 4GB configuration will provide a better working experience.
The maximum RAM that Windows Vista Ultimate can recognise is 4GB, as long as you have the 32-bit edition. If a 64-bit edition is being run then up to 12 GB RAM can be supported.
Since the only difference in your detail - is the amount of memory (4GB against 2GB) - go for the 4GB machine. The extra memory will help Windows 7 run faster.
The laptop in question comes with 4GB of RAM.
