A while back I uninstalled HP client security and HP device access manager, ever since I done that I can no longer access USB device such as thumb drives or external hard drives. I tried reinstalling both, client security installs but now won't uninstall... HP device Access Manger errors out during install. I tried the CMD commands to takeown/icals and it says it can't do that... The drive was able to be seen before removing those HP products. Anyone know of another way to fix this issue?
