A couple weeks ago, I upgraded to Windows 10 OS. When I opened LR and PS CC, everything looked as it should on my monitor. However, today, when I went to print a test image, I am getting streaky areas with various colors and I am about a stop or so too dark. Mind you, everything was copacetic with the same software and Win8.1-64. I checked for driver info on the Canon site and apparently the same drivers for 8.1 work with version 10 (ie, no updates). Anyone experiencing similar phenomena? Do I have to retrace my steps and empirically work out the right settings? Also, in the Print module for LR, I only have a choice for printer managed color although under printer setup I have "No Color Management" set. I have not tried printing directly from PS, but thought I'd throw this out there in case anybody has a bright idea. I searched the forum for Windows 10 and Windows 10 printer drivers, but found nothing, but I might have missed a pertinent previous thread.
