[Windows Central Question]

Dear Sir,
I am using Lumia 950 XL. I faces problems of screen goes black & restart phone. Once I reset phone,but till problem remain same. Now I roll back my phone to Os Build 10.0.10586.318. Now its work fine. But in update is automatically downloaded newer Os Build directly 10.0.14393.953,but I till not restart my phone bcoz it will install newer version. My question is that if I install this downloaded version then it will update to 10.0.10586.318 (version :1511) or it will change version which I was using (where problems faced) Version :1607? What should I do? Update? how to stop this downloaded version to install ? bcoz I hold my phone not to restart till today.
