I was waiting for you to say that. But in my experience, unless there are serious issues with Windows, there is little benefit in doing a clean install, as Windows will (almost always) run just fine after updating. It's much easier to run Windows Update than to manually reinstall the apps you use. Windows still runs quite fast on my 13 year old laptops after upgrading to new builds.
An ex-MS employee shared my point of view (can find the thread somewhere here).
Clean installs have almost zero issues (if you were smart enough to keep your drivers somewhere in case of).
Upgrades? enormous amount of users posting having issues afterwards.
- clean install of Win10 itself around 15-30mn vs Win Update 1-2hours.
- clean install has no leftovers, no corrupted registry entries/drivers/files, no windows.old, etc...
- most of my apps aren't installed, they are portable, so not much hassle and waste of time.
Not saying right after a clean install i can make a clean system image 100% free of malware, cant say the same for an upgrade.
Clean install is my favorite method, so my computer habits are oriented to maximize clean installing.
I can trust my system because i know it is always clean, not saying i restore my 100% clean system image almost every 2-3 days, took 10mn.
This is reason i don't care much anymore of security software, and since i use Enterprise version (with its boatload of security features) , it is even more true.
We do have Reset now in Windows 10.
tried once, it failed miserably...
