I'm currently running Windows 7 and am happy with it. However, it would be a big help for the computer to boot up quicker than it does now (takes about 45 seconds).
A little history: it used to take a couple minutes from the time I pushed the power button until the Windows start-up was complete. I replaced the old rotating hard drive with an SSD and that made a very big improvement...........it now takes about 22 seconds for the POST, and an addtional 23 or 24 seconds for Windows 7 to start up.
I've heard that Windows 10 has a fast start up, but I am concerned about the drivers............I've heard that there might be problems with the drivers, especially on older devices, and I would rather not take the chance unless the new start up time is much faster than the 23 - 24 seconds that I currently have.
Also, I hear that Windows 10 does automatic upgrades and I don't like that, but I thought that I read somewhere that you can change the settings so that the upgrades are not automatic.........not sure about that.
So, take the chance on having driver problems and upgrade problems? Naturally, the POST will always take 22 seconds (this is as fast as it will go even after making BIOS changes to speed it up). So, the best I can expect is to reduce the start up from about 45 seconds to sometthing less than that, but will never be faster than 22 seconds.
All advice appreciated.
