Windows won't update with an HP software update to Inboxstoragedriver istom.sys with this driver 15.

[FishinBob1]

I get a message that windows can't proceed with an update if I don't add HP software driver for inbox storage driver.  They recommend 15.9.6.1044 but there is no such driver on the HP site.

Thank you for posting on the HP Support Community.

This seems to be a new problem when updating to W10 version 1903.

One fix that seems to have worked for some folks is to navigate to:

"C:\Windows\System32\drivers", then find the iaStorA.sys driver and rename it to iaStorA_old.sys

Please refer to the HP expect suggestion from this link: https://h30434.www3.hp.com/t5/Desktop-Operating-Systems-and-Recovery/cannot-install-new-windows-10/m...

Hope this helps! Keep me posted for further assistance.
