Upgrading from Windows 7 to 10

I've been using Windows 7 for quite a while now, and I'm considering upgrading to Windows 10. I have a few questions before making the jump:

Compatibility: Are there any known issues with older software running on Windows 10? I've got a couple of legacy applications that I depend on, and I need them to work smoothly post-upgrade.
System Requirements: My current PC runs Windows 7 without any problems. How can I ensure that my hardware can handle Windows 10? Is there a tool or software that can evaluate my system's compatibility before upgrading?
Upgrade Process: What is the best method for performing the upgrade? Is it better to do an in-place upgrade, or should I go for a clean installation? What are the pros and cons of each?
Data Migration: How should I back up my files to ensure nothing is lost during the process? Is there a built-in feature in Windows 10 for data backup and recovery?
Windows 10 Editions: I'm not sure which edition of Windows 10 I should choose. Can someone provide a breakdown of the differences between, say, Home and Pro, and what might be most suitable for an average user?
Overall Experience: For those who've made a similar transition, what has your experience been like? Are there any tips or tricks you’d recommend for someone moving from Windows 7 to 10?

Any advice or recommendations would be greatly appreciated!

Upgrading to Windows 10 can be a great move! Here's a quick rundown:

Compatibility: Many legacy applications work, but it's best to check with the app developers. Windows 10 has a "Compatibility Mode" that might help.
System Requirements: Use the "Windows 10 Upgrade Assistant" from Microsoft's official site to check hardware compatibility before upgrading.
Upgrade Process: An in-place upgrade is easier and retains your files and settings, but a clean installation might give you better performance. Consider backing up first.
Data Migration: Use tools like Windows Backup or third-party options like Acronis or Macrium Reflect to secure your files.
Windows 10 Editions: Home is great for most users, but Pro offers additional features like BitLocker and Remote Desktop, handy for more advanced needs.
Overall Experience: The transition is generally smooth. Explore the new features to get the most out of Windows 10, like virtual desktops and the new Start menu.

Consider starting with the Upgrade Assistant to assess compatibility. Good luck! Any particular application you're worried about?
