I have Win 10 Pro (ver 1607 Build 14393.222) and I find that Windows keeps changing programs that I have SET for things like graphics, pdf, and HTML extensions.
I use PDF-XChange Viewer by Tracker Software as my PDf viewer – it is a great program, solid and reliable and always has been.
I use Irfanview for most of my graphics (jpg, png, tif, bmp, etc.) because for viewing, quick edits, re-sizing, placing text and boxes, circles, arrows, etc. is fast, easy, and simple. I use Paint Shop Pro and other programs for serious work but Irfanview is the best for taking a screenshot, marking it up for directions for folks that I help.
My browser of choice is FireFox and I don’t want Edge except now and then if a video wont play in FF
Here’s the rub, Win 10 loves to change PDF-XChange Viewer to EDGE, it changes Irfanview to PHOTOS, and it changes FireFox to Edge too. I have set these various ways, used Settings, and done the defaults, by extensions, and by Choose a program with the “ALWAYS use this program” option.
Windows changes these at least once a week and it drives me crazy – what is going on? Is there a way to lock in my choices because the tools in Win 10 don’t do it.
