I agree with pcpunk & Gary, though both runs Windows for different reasons & so do I, both 7 & 8.1, as well as one XP Pro install that never goes online, that I'll keep there as long as one friend who depends on me for support continues to run the XP Media Center Edition, a modified version of XP Pro. Yet I've told him not to refer me to others running the OS under any conditions, otherwise would be requested to assist others with their vulnerable OS.
The reason why I dual boot isn't so much for myself, rather to assist others as noted above. As much as I'll dread it, will have to create one Windows 10 physical install, in addition to the one running in a virtual machine on a PC that I can't carry around, to assist users on this Forum & close family members & friends running the OS. Some, but not all has made the leap to W10, others are still considering as the clock is ticking down for the free upgrade. Which because of lower than expected adoption rated, may be extended.
Like Gary pointed out, the only person who can make this decision is you.
You can run both, and if your computer supports running two drives, here's what I recommend. Disconnect the Windows drive's power & data cables, install your choice of Linux on another drive, run the update on it, shut down & plug the Widows drive cables back in. Go into the BIOS or UEFI & make the Linux drive the first one to boot, press F10 or whatever key to save & reset, then you'll boot into Linux.
Now open the Terminal & run the following command, and provide password at the prompt.
While there, may as well activate the Firewall, if you perform both actions at once, won't need to retype password.
sudo ufw enable
Finally to make sure all is OK, reboot, select the Windows install from the drop down Grub menu, Windows should fire right up.
This gives you the best of both worlds, you can run Windows as needed while running Linux. If like the rest of us long time Linux users, you'll find yourself booting into Windows less & Linux more. Another benefit is that one doesn't have to wait until Patch Tuesday for updates, any exploits once found, will be fixed usually in under 72 hours, including the time to distribute to different distros.
Being that Linux OS's are free of cost, plus one gets a full featured Office suite included, all of the tools to get started are there. Most software is in the Software Manager, though browsers such as Google Chrome & Vivaldi will have to be downloaded, be sure to choose the version (32 or 64 bit) that matches the install.
Finally, if coming from a Windows 7 environment, then Linux Mint MATE 17.3 is an excellent alternative. Just make sure to download the correct bit version for your computer, 64 bit version below.
Here's the 32 bit version for older computers.
That's my two cents worth, Good Luck with your decision!
