then there is no restore option. To revert to Windows Vista you would have to reinstall Vista from the Vista setup disks.
Which computer networks are you talking about? Do you mean the internet connection supplied by your ISP and via a wireless router? If so, you may have to setup the wireless network again.
I have a Compaq Persiario F500. My computer is loaded with windows Vista. I looked up Windows 7 avaiability update and my computer no longer logs into the wireless networks. I can not even get it to restore itself to previous dates. Any ideas or help will be greatly appreciated.
