Announcing Windows 10 Insider Preview Build 14901 for PC

Correct me if necessary.....an in place upgrade is not using an ISO?

An in-place upgrade is an upgrade install where installed software and user data are left in-place and are still available after the upgrade, only upgrading the core OS in existing Windows installation.

As such it is the opposite of clean install which does not keep installed software and user data.

I've been running the insider as my primary for about the same time with similar results. But in my case I just took the dive and I didn't dual boot with 8.1. I'm a risk taking rabbit.

I had bad experience with Alpha and beta versions of W8 so I didn't trust W10 at the beginning.

I was lucky and I never have had an issue with the beta of 7 or 8 so those results motivated me to take the dive right into the insider for 10.

To confuse matters, you can also upgrade selecting not to keep data and software. I call this a "fairly clean install" but this is not as clean as a proper clean install e.g. registry contains detritus from old install. I think it keeps old drivers as well.

And than there's also "Bare metal" setup.

Is not creating an ESD to ISO and installing clean.....not an upgrade install....ie:- including detritus left behind from previous iteration.
An upgrade to the average person means an upgrade, users outside of these forums would not have a clue on creating an ISO from an ESD.

Clean install is clean install.

• Any installation started with booting the PC with Windows install media is clean install, regardless what kind of install media is used (self made ISO burned to DVD / USB, Windows install DVD / USB bought from MS Store or any retailer and so on). A clean install can be done by wiping the hard disks empty removing all partitions, or on top of an existing Windows installation in which case old installation is moved to Windows.old folder.
• Any installation started with launching Windows setup from desktop of an existing installation and selecting to keep installed software and user data is an in-place upgrade install, regardless what kind of install media is used. If user then selects to keep nothing or only user data it is an upgrade install, not an in-place upgrade.

Having never used the ESD to ISO method to upgrade during the Insider programme, always did the conventional method, thinking M$ would be more concerned that the user would find any bugs encountered in the course of the update.

Thank you for your concise explanation.
