If I use the word "you" or "your" in the following it is meant for all of humanitry for the record and not any individual poster who may take offence to it. I am simply sharing information. It's not hard to stop the update if you don't want it. I understand some folks reluctance to change. I even suggest to some people daily that they do not upgrade. Every case is different and every computer is different. Hey, I hung onto Vista forever on one machine. Vista, another version noone liked. It worked perfect for me and I do an aweful lot of things on a computer. My apologies if I gave any of you the wrong impression. We'll just have to agree to disagree about it's merits. I had to buy a new sound card and actually while I was testing the preview, I decided to build a new machine to suit which is perhaps the best way for most people. I DID toss a lot of programs in the pre-upgrade preparation period and I believe probably a lot of those programs probably wouldn't run on win10. Microsoft has stated that win10 will be the last version of Windows. Time will tell. They will support win7 for many years. A huge amount of businesses just switched to it recently. It often takes IT sections years to figure out things like that and then they adopt the old version. A lot of people got a shock when they stopped supporting xp since it would come up with an error if it tried to connect to the update server since it was gone. I kept a lot of people going a bit longer by simply turning off auto update but of course without keeping up to virus' malware, spamware. Yeah. xp. There will come a day when Win7 will go the same route. It will be many years. If you don't see yourself connecting multiple devices, never think you'll need direct x 12, don't care about enhanced security and improvement in the underlying operating system code, can't see yourself getting into virtual reality things, don't want the ability to walk into a room and have your windows 10 phone connect to your TV wirelessly, don't care about things like the oculous rift, the holo lens, don't expect to live a long time, Win 7 will do you just fine. If any of you think you may want to get a new wiindows 10 machine, I can't recommend highly enough to get one with a 64 bit version of Win 10 on it. This part is important The last two programs I installed on my machine were 64 bit operating system only. Hello. So good programs are being produced as 64 bit only. Of course they are. They are incredible and need the speed. The free Win 10 update only updates from what you have to what you have such as 32 bit home version to 32 bit home version. 64 pro to 64 bit pro and such. What does this mean? It means good software companies are making good software designed around good fast operating systems. If you (not you overlock. this is info for all) want to run the latest software that requires speed and power look out, it'll have to be win 10 64 bit and not just win10. Food for thought? Free update? Yes. version to version. Most will be updating in short order. Great things are coming very fast. Programs are starting to require more data paths and better processors and memory. A win7 machine? If it is a 32 bit version and machine, it is a great candidate to practice win10 on before you get your new 64 bit beast of a machine running direct x 12 (only win10 supports that ,I hear.) that will itself be obsolete in 5 years. Dual core, quad core, 6, 8 core processors. My brother is writing code for 128 cores right now. He runs nothing but Linux at home and at work since it is java based programming which is not platform dependent. Copy all your data somewhere else first. My recommendation? Most should not update but simply buy a new machine designed for the future running 64 bit Win 10. Unfortunately, it is neare impossible to BUY a decent machine. One has to build their own to get in the real ball park. If you do anything that requires power such as movie creation and gaming. Win10 does not like older hardware. You would be better to sell me your old laptop for $50 before the rush so I can install Linux on it and be happy happy happy. At least it will still recognise the mic and cam. The free update or even previous versions if 32 bit is just a very short stop gap. Microsoft knows you will have to buy either a 64 bit operating system machine or a copy of win 10 64 bit within the next few years anyway. Now don't go rushing out to buy Microsoft stock right away. The line forms behind me. They are about to rock the computing world.
