4 months ago I bought a new HP laptop with windows home 64bit and 4GB of ram. I was told this would be enough to run Elements 15. It worked ok for about 3 months. Then it started saying.Not enough RAM to perform this task when converting DNG file to Jpeg. I checked the RAM and it showed 2gb being used by a commpresed file. I went through all the files and apps. Uninstalling one at a time. Non of them made a differance to the RAM. My question is . Should windows 10 take up 2gb of ram. I have returned the computer and got a refund. So this is an academic question.
