The same! Windows 10 seemed like it started out stable enough, but it’s been getting flakier by the year for me. I’m now keeping a log of things that go wrong with it, just for fun. Every once in a while I look at the list and ask myself, how on earth did they screw up start menu search?![0]
There are ways for us "end-users" to get a hold of LTSC. First download the demo from microsoft then go to ebay to buy a key from some shady guy for 14$. Seems to work for me :P
