I have just had to get a new PC and opted for Windows 10 because Microsoft will stop supporting Windows 7 in 2020. I was expecting to have to buy PSE 2018, since Adobe say that only PSE 14 or later will run on Windows 10. The Windows 10 updates are all up to date. I hate being forced to update software I am happy with, so before throwing away my 2009 vintage PSE 7 CD and spending money on PSE 2018, I tried installing it on my new Windows 10 PC. And everything appears to work perfectly. I have opened DNG RAW files (I purchased a Pentax DSLR so I get DNG RAW files straight from the camera), made changes, saved them as JPG files. I have also opened JPG files, made changes and saved them to new versions. I have never used PSE's file organising/keyword/tags options, preferring to set up my own folders and always use the 'open with' option on a RAW or JPEG image. Perhaps it is the bits I don't use that don't work with Windows 10. Has anybody else put PSE 7 on a Windows 10 PC and had problems?
