Update: 2019-01-12, after many failed updates and upgrades through the update system in win10, I gave it one last stab today. I stumbled onto a link someone posted for using the Windows Media Creation Tool to update and upgrade. Never used it for anything before. I just spent a couple months using the win10 as it was loaded with my non-sp1 version, with blocking all updates. It works, but many features don't fully function without updates(The store or some apps). So I clicked on the link in a forum post(where I cannot remember), which sent me to the Windows tool that loaded Windows 10pro. I already have win10pro. OK, this is getting scary at this point, since I had no idea what was ahead of me, so I disconnected a few hard drives, and double checked to see if I cared about losing some stuff. Moved forward, and it loads a fresh upgraded copy of Windows(build-17763) on your computer, without all other upgrades/updates in between that broke it before. Everything actually works perfectly(so far), like win10 did before. The onboard update system must have been corrupted, and many people were complaining of the same corruption for their updates.Before the October Windows upgrade, there was two or three different upgrades, and made my win10 flip out. This TOOL put the October UPGRADE on my win10 immediately(Took some time to download). For all of you out there with update troubles , do this, it is like a miracle. This loads the freshest/stable copy of win10. Even my Creative X-Fi sound card is still working, and it was always crushed by any update beyond the initial install disc drivers. I still doubt that MS has added drivers to decrypt Canon digic 7 camera photos in its MS photos app. So, hopefully win10 will now be stable again for at least another year and beyond.I did also stumble onto a section at MS's site that sounded like you could download or install the October 2018 upgrade, but did not investigate it further. Trust me, I looked for that at MS's site before, and it is always hard to find things you need at MS's site. MS has lots of things that say download this here, and when you go there, there is NO DOWNLOAD. Hahaha on me! Had to click on a link in a random internet forum, who knows where, to get the answer I needed for this latest fix. I've called MS about these update/upgrade dilemmas before, and the country of India could not find the answer between 2 billion geniuses. Remember when you could call 'BOB' the computer genius, at the computer company? All the BOB's are on disability now, and downsized out of work. I hope some of this helps someone out there. Especially folks that upgraded from 7,8,8.1, etc., this may be the panacea of updates.UPDATE: 2018-12-20, Well, I really loved this Win10 computer build for almost two years, and then the updates and upgrades started coming hot and heavy from MS. I spent good money buying the best components too. My Creative sound card quit working all together eventually(1809 upgrade). Google Chrome was toasted time and time again, and I have everything on Google Chrome. Windows Edge runs like garbage now too. You do not have a say so in how the computer updates, and does not do any assessment for incompatibility of your components. After tons of so called 'upgrades' MS downloads and installs, you end up with chow suey. My fast win7 computer is still zipping along and passing up my much faster win10 build. I really feel sorry for all the people with slow computers, old windows Vistas/7's/8's computers with FREE upgrades that have just quit working with no wifi, no sound, no video, and peripherals getting wonky. Oh yes, my Logitech mouse is worthless now too.Windows computers, as opposed to Apples, gave you the freedom(like America once) to install components and programs, and have them function for years to come(like my win7 computer), but now, MS upgrades your equipment and leaves you with a choppy Edge browser, and failing peripherals. Win7 let you pick the updates you needed. We aren't running the Pentagon and don't need all the National Security updates to protect the Nation. Win10 is kinda like CA, the government adds people and subtracts your money without your approval. Is this communism computer control?Another feature of win10 that was wonderful, the photo app that gave you a great array of tweaks for your photos. As time went on, even that app got worse. It is never updated. Updates are only features you'd never use. I recently got a new Canon 77d camera, and the non-updated MS photo app will not process 77d RAW files. All new Canon cameras have the newer Digic7 processor, and MS photo app won't fix those RAW photos.The wonderful Media Center from winXP-win8, gone. What do we get, Windows Media Player that looks exactly the same boring way as it did 12 years ago on XP. Really?? Same features and functions too. NO NEW FEATURES AT ALL? We can actually thank lawyers for part of that, why, they sued MS for monopolizing its features on Windows. Try hooking up TV, and that gets more complicated too. Instead of windows getting smarter or including more features, we get a bland communism of nothing. What does a win10 computer do? Not much, inherently, but will play video and music on its ten year old player. I didn't even get a FREE freecell card game.I never thought I'd say it, but the days of the computer nerd are numbered, and we are just going to be using tablets or Apple computers in the future. You can't do anything with an Apple computer either, unless you buy expensive software. When they break, we toss them out instead of replacing some worn out parts. The apps on the MS site seem absolutely worthless to me. Remember the old days of buying a box with software in it, installing it, and marveling at its uses, gone! We useta know our next door neighbors too, but they don't speak English anymore.There are a number of sites on the internet that will show you approx' 4 ways to block win10 from updating or upgrading, and bricking yer computer. Go there! One meters or blocks the amount of data your wifi can download, which blocks upgrades. The simple one is turning off updates or delaying updates, but MS updater knocks those walls down easily now. Two other more effectual fixes involve going in to the registry and turning off or disabling updates on a more permanent basis. I've done all 4 these after reloading my computer three times in a month!! Hopefully this fixes the fixers of MS. My Creative Titanium X-Fi sound card works perfectly now, but has no quick launch console. The features are split in two windows, but everything is there, from bass to EAX functions. I have virtually no updates on the win10 now. MS says it will block updates some time in the future, if you don't stay up to date, GREAT!! I just tried to download and play the recent demo version of the Tomb Raider Shadows game on STEAM and it is telling me I don't have enough updates to play it, oh well. You can't win, for trying to win.I can't go back to win7 on this computer, because I've installed an M.9 Samsung SSD HD for win10, and the options for installing win7 on it seemed like too much work. Should have kept my Samsung SSD on there and then put win7 on this win10 mess, and may still. Would pick up all features on my Creative card, video card, and the best thing, Media Center(TV, DVD, radio, videos, music, pictures, and more). Win10 provides heartache galore though. My Google Chrome runs awesome with not one update on win10. See, I can say something nice. I feel like the guy that owns the fastest car in town, but it is always at the mechanics shop and needing tuneups.My bottomline advice, get a decently fast computer, Intel i5 or i7 processor based, and put windows 7 on it, and it will run win7 like you've never seen a computer run, fast. When MS shuts off all downloads for win7, we will be forced to buy win12 communism. I recently rebuilt a friend's computer on win7. I got him a 32" Dell HD monitor, and a decent video card for his stock HP computer, and he now has a classically fast Cadillac version of windows 7. He can't believe the difference. Forget win10, if you can. Good luck folks.Original review before upgrades: First, DO NOT UPGRADE!! BUY THE DISC FOR $100!! All the reviews on Amazon that slam Windows 10 are from non-verified purchases from FREE upgrades through Windows Update. They all ran here to complain about their poor decision to try and get something for FREE. If you want the best operating system, BUY IT, and have it run perfectly, NOT UPGRADE. UPGRADE ONLY, if your time isn't worth anything and you have hours to spend on line getting it to work properly. Spin the wheel and get lucky? Most all the positive reviews for Windows 10 are from verified Amazon purchases of the disc. My friend got her laptop to upgrade because she knows computers and spent a lot of time with Microsoft on the telephone.Here's my Amazon'd system I built:01. i7-4790k LGA115002. Gigabyte Z97X-UD3H motherboard03. Gigabyte Nvidia GTX960 Windforce 3fan 4gb vidcard04. Kingston 4x8gb HyperX Fury 1866mhz PnP(non xmp)05. Samsung EVO 500gb SSD(upgraded to Samsung M.9 500gb)06.

Pioneer BD-rw BluRay/DVD/CD writer12. (next) Hauppauge 2255 HDTV pcie tuner(never did install)I put all these parts in the case and loaded Windows 10, and went to pour some coffee. It always takes a while to run a new build. I returned with my coffee, and the computer was asking what I wanted to do next, done, WHAT? Made me want to build these 4 profit it was so easy. Maybe I should have loaded win7 and spent a couple days upgrading, hahahahaha!!I decided to test how efficient win10 was on a tough customer. My i7-860 was starting to slow down on the higher settings for the new Tomb Raider game. I loaded win10 with 16gb of memory and onboard Intel Graphics. TR would surely win this matchup. Nope, the system ran TR on normal just like my other i7 computer with win7. I have never seen a video game run on motherboard graphics, crazy!! Once I loaded the GTX 960 vidcard, TR had no chance, and rolled over to play dead at the ultimate high settings.The newly replaced start menu is a nice compromise for all us familiar with Windows. I loaded up Cortana the verbal assisstant for the new win10. I need to get a new microphone, but the interface seemed to work quite well, and responded to my commands even with my crummy microphone. I know I have others stashed somewhere, but can't find 'em. I does take a little time to get it going, and the there are prompts that seem to go nowhere at times.I put Adobe Lightroom and Nero 2015 on the win10 and all seem to run perfectly. The app for movies, TV, and music took quite a while to load and haven't been back to it yet but it did work. I have quite a bit of media, but Nero loaded much faster. I want to remind everyone that the crown jewel in the Windows world is not around anymore, MCE. Media Center ran TV, music, movies, Netflix, photos, etc. from one slick interface. That is history. You are now left to fend for yourself on how to get TV and other media to play. Between lawsuits and tired of answering questions, Microsoft wants to only be an operating system with you using apps like a Mac computer. Is the day of the tweaker a thing of the past?All the hardware old and new I threw at it has run wonderfully. Most of the hardware and software from recent years has been updated to win10 drivers. Even some of the old drivers work too. I've been running win10 for only a month and am looking forward to using my new usb3.0 ports with 3.0 equipment I've owned for a couple years now, but ran on 2.0 this whole time. This computer is very fast, and restarts so fast it is nutty. I noticed in the Gigabyte motherboard bios it had two settings for faster booting, really, how is that possible? The minute you hit the restart button Win10 is back? It is already lightning fast to restart on slow mode?I will try to update this once I've had some experience, hopefully still good.
