seems easy enough , The pitfall of installing an update that could wreck the OS however has me thinking twice about it.
I've been reading up on running XP in VM on Linux. No updates required , but there are issues ...
I have a couple of machines running XP offline.. using them for utilitarian purposes , Editing video, transferring files across drives and for the "record what you hear" feature, recording music from Beta VHS Vinyl eTc.
Alas, upgrading to Win 7 has it's pitfalls as well... like driver issues and the Fn hotkey software on laptops.
I upgraded a Toshiba Netbook by shrinking the C: drive and creating a Partition for Win 7... Good thing too.
Before I started the win 7 install I'd turn off the WiFi before shutting down XP with the Fn hotkey. .. When I booted into win 7 for the first time I couldn't Turn the Wifi back on because the hotkey software Toshiba
said would work ~wouldn't. I think it's called "Extra value package" ...

....
.. anyway I booted back into XP - turned on the wifi via hotkeys, then booted back into win 7 and was able to connect to my network.
Cheers
