Some quick advice for those of you about to open up new PCs bought for Christmas (for that matter, the advice is equally applicable whatever the occasion)… avoid the temptation to dive straight in and have a play. Instead, take an image of the hard drive as it arrived from the factory – yes, you can always use the manufacturer’s instructions to return the machine to a restored state but this can take a long time (as I found a few weeks back when I succumbed to temptation and had a play with my Lenovo Idea Pad S10e before imaging it!).
As I write this, I’m setting up a new Dell notebook for someone (an Inspiron 1525) and the first key I pressed (after the power button) was F2 to go into the BIOS. Here I changed a couple of settings (boot order and numlock key state), then booted again with F12 for the boot menu to use my device of choice (floppy disk drive, USB drive, or PXE network boot) to boot to my image capture software of choice (Symantec Ghost, Windows Deployment Service, you name your poison) and take an image of the entire drive (not a partition).
Following this, I can can configure the device as intended (remove the crapware, install some AV software, install an Office suite, etc.) and then take another image when I’m done.
Of course, for corporate deployments it’s normal to blow away the manufacturer’s image and install something more appropriate to the organisation’s requirements but, for home and small business users, it’s perfectly acceptable to use the factory-supplied build and this might just save you some time if you ever need to return to square one.
