Our local library recently purchased five Gateway Profile 6 computers, all running Vista Business. Besides all the other glitches that came along with Vista, none of them will run Windows Update. They simply show an error # 0x80073712. In addition, when I go into Windows Features, the dialog box is empty. The troubleshooter on the internet suggested using this command: reg delete HKLM\COMPONENTS /v StoreDirty When I tried that, I am given a message that the registry key does not exist. When I called tech support for assistance, they claim there must be a file corrupted and suggested I reinstall Vista. If that were the case, why would I have the same problem on five different computers? Any suggestions?
