I went ahead and downloaded/installed Win10 last week. My most used programs such as ProQ Designer, Quicken, EQ7 work fine. When I went to view one of my videos though I had issues. Also I use YDT Video Downloader and now I'm having issues with it. When I went to print a page in ProQ it said there was an error and couldn't print the page but it did anyway. My internet (Google, Yahoo and AOL) I have no issues with so far. I think I opened up Embird too but can't remember so won't say one way or the other how it works. Haven't downloaded/installed on my laptop yet.
