This was my fourth attempt at Windows 10. (One being the technical preview.) The oldest PC (Athlon X2 3600+) ironically being the most stable.
I notice a lot of the major manufacturers ASUS, Toshiba, spring to mind, haven't released driver updates yet. Usually this is done before any new OS. (My P755-116 Toshiba laptop did not like it one bit, and I reverted almost immediately, because of lack of driver support.)
On my personal PC (i7, Sandy Bridge, nVidia GTX470, very generic hardware) this happened:
I haven't seen this many “Blue Screens of Death” since Windows (Bite) ME back in 2000.
I upgraded from Win 7 Pro SP1. The installation was mostly smooth, although I did restart the PC because I thought it had stopped responding, and it carried on OK after that.
After I had de-selected all the privacy options in the custom setup, it booted pretty quickly (it's an SSD after all) and seemed to be quite responsive once I installed the nVidia graphics driver. It broke Kaspersky IS 2015, but I had anticipated this and re-installed KIS 2016. Everything seemed good at this point.
Then Win 10 started installing updates. This is when all hell broke loose, it tried to install a wifi NIC driver for hardware that was not (ever) in this PC. I got a continuous looping “System thread exception not handled” BSOD error.
So I booted into safe mode tried to remove the update, no luck, I still get a looping BSOD. I try a system restore from the boot options, and it fails with an “Unspecified Error during System restore (0x8000ffff).”
So back in safe mode I try a system restore again it works this time. I make the network connection “metered” so it doesn't reinstall the windows update driver again.
Only now I have another problem, I can't install updates without re-enabling the driver update that killed the OS.
I've installed all the latest drivers and Windows 10 still wants to download it own drivers. Eventually after some searching around I find a tool on the MS website to “hide” driver updates, this only sees to work if you edit Group Policy driver management settings. But I'm afraid to enable the updates again, which is problematic because it's either on or off, I can't choose an option that's appropriate for my system.
That was the installation experience, now I'll provide some personal observations:
1. Forced driver updates – BAD IDEA, PERIOD.
2. Forced updates – I understand why MS would feel compelled to do this, but I still think the risks outweigh the rewards.
3. I didn't upgrade to Win 8 because the “in-yer-face” sucked. The return of the start menu is an improvement, but it's still full of clunky, flashing blocks. On top of that, some programs in the menu are “shortened” so they look very similar to other options in the same folder, and the only way to tell is by clicking on them. As far as I can tell there is no way to scale this. Fortunately, this can be fixed by installing the 3rd party “Classic Shell.”
4. Wifi-Sense enabled by default, to give all your contacts immediate access to your network is a security nightmare waiting to happen. If “I” want to give someone access to my network, “I” will give it to them, Period.
5. Windows 10 obtaining updates from other PC's on the network or other PC's on the internet is a zero-day security exploit waiting to happen.
6. Cortana is a non-issue for me because it's not available in my country (and probably won't be for a while.) But the privacy surrounding it (such as harvesting voice, text, IM, and email data) would mean I wouldn't enable it on my PC anyway.
7. Windows 10 isn't free. By this I mean, while it may be a free upgrade for existing Win 7 & 8 licence holders, you will still pay for licenses for new devices, or new installations. As far as I'm concerned that means: IF I PAY FOR A LICENCE, there should be NO ADVERTISING or ANY HARVESTING OF MY PRIVATE INFO FOR ADVERTISING OR ANY OTHER PURPOSES.
8. Win 7 had DVD support built in, not so in Win 10, you have to pay extra for that.
9. Advertising in Solitaire? Pay to remove. (It's been a staple since Win 3.1)
10. Removing Windows features requires the use of Powershell. No easy access.
11. PRIVACY issues. PRIVACY issues. PRIVACY issues. - Therefore SECURITY issues. Need I say more. Microsoft, my trust has been lost.
I appreciate that every new OS has it's teething problems, but if I wasn't a techie I'd be seriously up the creek with this version of Windoze.
I'd really like, to like this version of Windows. I really would, but with the forced updates and the MAJOR PRIVACY issues, I have no alternative but to revert to Windows 7.
