EarDemon, please provide a few examples of where W10 beats W7.
As always your mileage may vary, some of this is more geared toward a work environment, but here's what I like about Windows 10 versus 7 after using it almost exclusively at home since day 1, and on one computer at work.
1) Quicker, snappier more responsive on boot up and shut down. (With Fast Boot DISabled on Windows 10)
2) File Manager is more robust
- More reliable when copying or moving hundreds or thousands of files that add up to 100’s of GB
- Long file paths are less of an issue
3) Better native multiple display customization, some of which was first introduced on Windows 8.
- The ability to have unique wallpapers
- Customization of taskbar on multiple displays
- Scrolling on inactive display (and Inactive Windows on same display)
4) Advancements to the CMD Prompt
- Full screen
- Ctrl+V keyboard shortcut now supported
- Word wrap
5) Improved DLNA support (started in Windows 8)
6) No need for third party tools to mount ISO images
7) I find the View Ribbon in My Computer on Windows 10 a much faster solution to Show/Hide Hidden Files and Show/Hide File Exts then going in the Folder Options Control Panel and going to the View Tab.
8) Notifications on lock screen
9) Native PDF Virtual Printer
10) No error 0x81000037 when performing a Windows backup on a clean install of Windows 10 like on Windows 7 that I've experienced oh some many times because there not enough room to create a VS copy of the boot partition
And then there's the Windows Store. Not many useful apps, again YMMV, but I do like a few of the apps like the ESPN app, don't really use Pandora much, but when I do it with the WIN10 app, and I like the unofficial TWiT TV apps that allow me to stream to my PC and then using the magic of DLNA, send it to my AV Receiver so I can watch on my big screen. I find the Task Manager to be much improved as well. I don't use them personally, but Virtual Desktops may be of use to some people, as well as the One Drive integration which I don't use either. There is also Windows Hello and Continuum if you have supported devices and Direct X 12 if you are a gamer. And while I can't say for sure, since everything I own and use is only 1080p, I would imagine better scaling for extremely high rez displays. Battery life on laptops is not a big deal for me since I'm plugged in 99% of the time, but I have seen battery life improvements with Windows 10 over 7, but most of it is probably attributed to upgrading from HDDs to SSDs.
There are countless oddball issues that my users at work come across on Windows 7 (like how having the Preview Pane in Windows Explorer enabled can mess things up that aren't related to anything) that are nonexistent in Windows 10. And I usually try my best to recreate different scenarios using Windows 7 in a VM at home to rule out the possibility that it's an issue unique to how things are configured at work. I'm sure there are a few strange issues in Windows 10 as well, but Windows 7 can just be downright annoying at times with documented issues that have never been fixed but are not present in 8, 8.1 or 10.
Yes, I realize that there are many third party solutions to some of the things I mentioned. Display Fusion for multiple display customization, RoboCopy for copying files, CutePDF for Print To PDF. I'm not averse to using third party software to personalize Personal Computers. These are not locked down fruit computers, these are PCs that should be customizable, either natively or with third party tools. I’ve used Classic Shell within in months of it’s release because I cannot stand the Windows 7 Style Start Menu, and MS removed the ability to go back to the old one. But from a management stand point, it’s easier for me and my users if things like ISO mounting, printing to PDF and being able to robustly copy extremely large amounts of data didn’t require additional software.
All of four of my own Windows 10 installs and all of the Windows 10 installs that I've done for others have been clean installs, and have resulted in very little to no problems. Never ever would I do an upgrade install of an operating system. Clean install is the only way to go.
