XP Pro, SP3, IE8 Because I cannot sign in automatically after reboot to WLM, I tried various fixes that I had to do when I had the problem before. One of them was to regenerate the Protected Storage key: HKEY_CURRENT_USER>Software>Microsoft>Protected Storage System Provider I followed the instructions I had printed off, including exporting the key (backing up) and then copying child objects etc before deleting the key. After two or three reboots and a couple of shut down/restarts the key was not regenerated. I still couldn't sign in automatically to WLM after a reboot so I decided to replace the original key in the registry. I duly double-clicked the back up and was told the information had been entered into the registry. However, after a couple more reboots the key is still not showing in the Protected Storage System Provider folder.
