I installed a version of PC-Anywhere on my works laptop because I need to administer an old machine. It did warn me that I was installing a version that was incompatible with the version of Windows I was running (XP). I’ve seen this message before with Windows 2k, so I ignored it.
On reboot it blue screened and kept on blue screening.
No panic, started up in Safe mode with the network enabled.
Started up in safe mode without the network enabled.
Selected the System Restore option and asked it to go back to Sunday.
PC anywhere disappeared, I haven’t lost any data files, and it rebooted fine.
For once something works as intended and saved me from myself, well done Microsoft it worked really well.
Of course, on a Linux box, it wouldn’t have screwed around with the network configuration anyway.
