This LINK helped someone with the same issue.
Check the first post in this forum,this is a sticky post,a permanent post.
I have a HP with most of the peripherals and Windows xp. It is about two years or older. It came with windowsxp loaded, no disk. I backed up the operating system, about 7 disks.
Now it will not open, an error message pops up, leaving me high and helpless. It says "a problem is preventing windows frrom accurately checking the license for this computer. Error code:0x80090019." When I hit OK, it goes to Welcome buterfly owner.
From there I am helpless. I searched, but everything seems to point to pass word? What is Sticky Post?
