Windows 10: Clean Installation of Four HP Pavilion 15 Notebooks a la Shawn Brink.

Thanks to Shawn Brink for his excellent tutorial on clean installing Windows 10.

I have four HP Pavilion Laptops which had 8, 7, 7 & 6 partitions as installed by HP, believe it or not.

Now all have the necessary four partitions and all are working perfectly.

However...

When I had finished I see that, although all four machines have identical software installed, that the size of the installation on the fourth machine is 2.3GB smaller.

I.E. 16.4GB - 16.3GB - 16.4Gb and only 14.1GB on #4

Programs such as disk explorer do not reveal anything, and Clean Manager makes no difference either.

Nor does removing all shadow copies in Device Manager.

There are no Windows.old folders on the drives.

When using Ashampoo GmbH WinOptimizer15 undelete on the Recycle Bin I find thousands of unrecoverable (bad) or lost files.

E.G. #4 shows 10,803 files amounting to 1.80GB

Intriguing as #4 had been restored from the (now deleted) Recovery partition, first to the original OEM Windows 8 and then upgraded to Windows 10 v1803.

Just a guess but has this Windows 8 to Windows 10 procedure cleaned out old metadata from the C:\ drive, whereas the 'clean' Windows install has, maybe, left something on the drive, despite all the partitions having been deleted before the Windows 10 installation procedure automatically produced the four new partitions?

Guessing again, but might it have been better to delete all the partitions as instructed and then make a single C:\ drive solely for the purpose of full formatting it, and then deleting it again ready for the Windows 10 installation?

The 2.3GB difference has me intrigued.

Why is this?

E.G. C:\Directory , AppData, assembly\temp , SoftwareDistribution and Temp\PendingRenames, etc.

#1. 9,491 items - 1.64GB
#2. 5,884 items - 717.35MB
#3. 9,137 items - 791.77MB
#4. 10,803 items - 1.80GB

Any heads up on this would be very interesting, as I am no expert by any means.

Many thanks,

Ian
