My sister gave me her laptop (an Asus VivoBook S200E) to look at as it was running very slowly at times. The main problem was that it only has 2GB of RAM installed. With so little RAM, the memory usage was becoming very high when Windows Update was running due it using so much RAM. Sadly, no more RAM can be added to this laptop as the RAM is soldered to the motherboard. I baffles me as why Asus would produce a laptop which not only comes with way too little RAM installed, but also can not be upgraded. I have disabled Windows Update, and with it disabled, memory usage is fairly low. As a result, performance is better. Since it is not ideal to not update Windows, I am wondering if there is an alternative to Windows Update which can run automatically. I don't want something which has to be run manually. The laptop is currently has Windows 8 installed, but I am going to get her to update to Windows 8.1 from the Windows Store.
