Like everyone I don't want to lose anything.
Just a new operating system on top of the old operating system.

The problem is that the first couple of times I create a file, it takes
long (like twenty or thirty seconds), then the rest of the creations are
fine.

Same with moving files. Uploading files. Copying files.

The first two or three or four take ten or twenty or thirty seconds.
The rest move instantly.

This is after the disks have spun up.
Its related only to the "movement" of files as far as I can observe.

Perhaps I got a virus or a malware scanner or a keylogger or whatever.
Simplest most obvious thing to do is wipe out the old operating system.

But how to do that gracefully?

A "Repair" install is inexpensive.

Mount the Win10 installer DVD ISO file, or insert the Win10
installer DVD in the drive while Win10 is running. Execute
Setup.exe on the resulting DVD device in Explorer, to
kick off a Repair Install.

The installer will tell you that your Programs and User Data
will be preserved.

The old OS will be in C:\Windows.old for ten days before it
is auto-deleted. Or, you can use Cleanmgr.exe after the
system comes back up, to delete the old OS. Don't delete
C:\Windows.old by hand, as there are a couple very
nasty file system features hiding in there that Cleanmgr
knows how to deal with.

You can "revert" if the installation attempt fails, and
the contents of Windows.old (contains both the old OS
and any removed Program Files).

If the installer finds Program Files which are "not compatible"
it will remove them. This normally happens on a Win7 to Win10
upgrade, rather than a Win10 to Win10 Repair Install, so for
this case, *nothing* should be removed.

If this fixes something, great. If not, you've only
wasted an hour or two of your time.

You must have sufficient disk space for this. On a 32GB tablet
device, that can be a problem, and doing this to a tablet,
I don't know what to tell you.

If you're going to do a clean install, that's much more involved.
And if you actually wanted your setup precisely preserved,
could cost you money (~$50 per time). Alternately you
can fiddle with stuff by hand, but it could take months to
get all the old programs reinstalled after a clean install.

A clean install removes user files and program files, and
requires Windows Update to patch the OS from 17763.1 to
17753.451 or similar. Clean installs are reserved for cases
where malware has thoroughly riddled the system.

You can use Process Monitor, Process Explorer or the like,
to trace what happens on the slow cases. You can use the
limited forensic materials to take a stab at it.

The older OSes had the Superfetch service which I used
to disable, but I think that's been removed. Windows Defender
generally isn't as bad as the problem you describe so it's
probably not that. Windows Defender is annoying, and definitely
does harm (reduces file I/O by a factor of seven in some
cases), but there should not be a huge latency issue
for every little thing you try to do.

When Windows 10 introduces Containers, I expect the
OS to turn into Molasses, so we have something to
look forward to :-/ Containers and virtualization
have already been attempted by some AV products,
and I tell people to turn that off if they complain
about it.

Does this type of repair install remove all the vendor bloatware? Sony
Vaio?

Also, if done, how many of the extra partitions can be deleted and used
for C: expansion.? My wife's laptop has a lot more than the 1
reserved or UEFI. I'm almost sure it's the previous win 8 image and
maybe a partition for the vendor repair program, you were able to hit
some key at bootup and get the OS to launch a boot diagnostic.
