when I downloaded windows 10 everything was fine, 1 month before the anniversary update to windows 10 system Z showed up. After the anniversary update it went away. Today is Friday I noticed that system z is back, I have not had any updates or have I downloaded anything. Could this be a drive that is storing information on how I use the computer, and is it only on HP computers? It doesnt show up as a virus or a trojan, and it is 356mb with 301 mb free, using 55mb..

From time to time, Microsoft may create a drive called Z: to keep information for the update/upgrade process. Drive Z: may appear then disappear. Microsoft should tell people about this or hide it as default.

I had this Z Drive appear on my PC a few weeks ago and performed a system restore to get rid of it. It stayed away for a while until the next time "HP Support Assistant" ran a system check for updates, etc, and as soon as it was finished, the Z drive reappeared. I got rid of it again but after every HP scan, it returns, so it is definately coming from that, though what it's for is anyone's guess.

I guess that the HP Support Assistant downloads one large file from HP's web-site,
and "borrows" some of the computer's RAM (356 MB), and creates a "RAM-disk", and assigns 'Z:' to it.
The S.A. then "unpacks" that one file onto the 'Z:' drive, building files & folders on the RAM-disk.
Voila! You now have a "system tools" (virtual) disk-drive, with the most-current version of the HP Tools.
After the diagnostic tools have completed, it _should_ "destroy" the RAM-disk, and give the 356MB back to Windows for "general" usage.
Run a 'CHKDSK Z:' from a command-line prompt -- it will probably run *VERY* *FAST*, because a RAM-disk is much faster than an ordinary "spinning" disk-drive. Or, run a "custom" virus-scan, targeting the 'Z:' drive. Again, it will run very quickly, if it is a RAM-disk.

What I did do, was follow someone else's advice and it has worked every time System Z has appeared, which is whenever the HP Support Assistant has updated. Just type the following text into the search box, run the command, restart your computer and System Z will be gone.......... mountvol Z:\ /D (System Z delete)

I have had the same problem for a LONG time. My HP 7310xi printer is connected to my Windows 10 computer, through that modem, with an ethernet cable. When I connect to the internet , the printer lights up like a Christmas tree and stops responding. I was blaming it on the printer card reader but have had NO success in solving the problem.
I have the same printer connected through the same modem to my Windows 7 machiine with no problems.
