Win 10 Clean Install

I took my Asus UX32VD-DS72 i7-3517U 13" FullHD Ultrabook in because I could not Update win 8, which was required; apparently, before installing Win10.  

I instructed them to troubleshoot that issue then asked them do a "clean install" Win 10; minus all the Asus bloatware and the partitions Asus comes with: C:, D:, Recovery, etc.  I also gave them a 4GB flash drive for the Recovery files.  

When I got the computer back it was loaded with Asus software, and the Asus screen saver logo.  When I asked why that was they said; "Oh, we'll just remove all that", and proceeded to the Control Panel and, one by one, started removing the Asus programs. That made me very uncomfortable, to say the least. I couldn't help but wonder, if this was a "clean install", why all that Asus software  was there in the first place.

When I got home I checked the SSD for partitions.  As instructed they removed the D: partition but there is a 20GB  and  900 MB "Recovery partition", a 14 GB FAT and 447 GB NTFS "Primary Partition", plus a couple smaller partitions.

I checked the flash drive and it contains an 11GB Recovery file.SSD data
So I am wondering, if this was a "clean Install" why was all the Asus software still on the machine, and; if the recovery files are on the flash drive, why does there have to be a 20GB recovery partition.  I'm also wondering why is there a 15GB FAT32 partition.  

The whole point of a "clean install" was to  rid myself of Asus Bloatware and free up memory on my SSD.

I'm no expert; that's why I here (-:, so maybe the Recovery partition is required, so too maybe I need a FAT partition for "backward compatibility?", I just don't know!

Oh and btw; can I change the Drive letter on the flash drive without compromising a recovery process; or does it need to remain E:/.  I would like to change it to Z:

If they had to reinstall Windows 8.1 to correct a problem and if they did that from ASUS Recovery Media, then you got that stuff along for the ride when they upgraded to Windows 10.

Now you have Windows 10 and the license is at Microsoft, you can if you wish install Windows 10 from the Media Creation link and KEEP NOTHING when that question arises. That will be very close to a clean install but it will not remove the Recovery Partition so far as I know.

Also don't forget, one of the small partitions is the UEFI BIOS partition. Mine is marked Healthy EFI System Partition.

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

The 20 Gb  partiton is the Factory restore partition from Asus
if they offer to make recovery DVD - or usb bootable devices, you can delete it.
otherwise, i would leave it - or back it up on an external drive
in fact - that's your best option imo : backup the ENTIRE drive on an external one
then you can always restore it

They either restored from onboard recovery partition to Window 8 and then made onplace upgrade to Windows 10.
Or they got somewhere a bootable Asus Recovery DVD with Windows 10 and rolled it out on your drive.
After they removed all unnecessary programs from Asus you can consider it to be a clean install.

To change the drive letter on a non-system partition navigate to Windows Disk Management by right click on Computer - Manage - Disk Management.
Right click on a partition - select - Remove/Change Drive Letter.

Files on Recover thumb drive
I tried to look at the Recovery partition on my laptop but I guess that's not possible.

Are these the files I'd expect to see on that Recovery  partition?  Should I be able to use the recover files, on this thumb drive, instead of the ones taking up 20GB on my SDD? I'm just trying to get the most free volume on my SDD!

Or should I just start over, from scratch, and check the KEEP NOTHING option, which would create a new recovery folder on my thumb drive?

I'm just wondering if the Recover files, that are currently on the thumb drive, would recreate what is currently on my SSD, along with the Asus stuff and the Recovery partition.  

Does win10
Keep nothing
option also create a 20GB Recovery partition on the hard drive?
