|I'm trying to discover what causes the enormous amount of|
disk access on a completely fresh install of Windows even
when I'm not doing anything. Way back on my first Windows
computer running Windows 95, I found that software which
came with the printer was continuously listening for messages
and therefore somehow causing the HDD light to flash every
second. That software did nothing useful, I uninstalled it, and
the flashing stopped. I was never able to stop the flashing on
later versions of Windows, even without any printer software.
The new laptop I just got has actual disk access going on all
the time. I can hear it as well as see the light. Not literally
*all* the time, but an awful lot. I've been watching it a bit in
Resource Monitor, but I haven't learned what all those cryptic
process names are yet, so I can't tell what's happening. I'm
pretty sure a big chunk of it is various programs trying to call
home via the Internet, failing to connect, and recording the
failures in a hundred different log files, not one of which will
ever be put to good use.
The only things I've done in the last few days are disable tasks
and services I think I can do without, and re-enable the setting
in BIOS which turned off Bluetooth (which I don't need) so that
I can use the USB port and memory card reader which are
somehow tied to it. That worked.
I haven't studied the details of how Prefetch and Superfetch
work, but it seemed likely that they could be responsible for a
good deal of the disk thrashing, and I doubt they'd cut more
than a couple of seconds off the loading time.
OK. I got around to Googling the device name that came up
last time ("PCI Encryption/Decryption Controller"), and found
immediately that it means I need the Intel Trusted Execution
Engine driver. Uninstalling the Intel Trusted Execution Engine
was in fact one of the last things I did before I noticed the
problem in Device Manager. It looked to me like its purpose
might be to support the TPM, which I turned off in BIOS, and
then some website that I only glanced at said it could cause
problems, so that was enough to prompt me to uninstall it.
I hope I can figure out how to get it back. I also uninstalled
Intel Security Assist at the same time. It looked like they
I looked through the sheaf of pages where I'm keeping track
of changes to services, and the two pages for disabled tasks,
but didn't think to look at the page of programs I uninstalled.
