Windows 7 can run on a very old PC

A user by the name of "hackerman1" has installed Windows 7 on a Pentium II

I've always wanted to get a modern operating system to work on my graphing calculator. And we're about there, thanks to the efforts of a fellow (or strangly named lady) on The Windows Club forum. A user by the name of "hackerman1" has installed Windows 7 on his PC, which in itself is nothing to write home about. The catch here is that he's gotten a bootable, working installation on no less than a Pentium II system. No, that's not a typo--Pentium Two. The extreme...ly old machine consists of a 266 MHz CPU, a whopping 96 MB of memory, and a next-generation 4 MB graphics card.

Like a stuntperson who just keeps tempting death by pushing the landing ramp farther and farther back, hackerman1 didn't just stop with that meager system loadout. He continued to alter the memory amount, achieving success with two of three setups: 128 MB and 96 MB. Unfortunately, Windows 7 didn't seem to enjoy only having 64 megabytes of memory to work with, marking hackerman's stopping point with that version of the experiment.

That's not to say that he's planning on stopping for good, however. Next up? A Pentium I machine featuring a 166 MHz CPU paired with a 1 MB graphics card. After that, maybe hackerman1 can break inject some Aero graphics into his trusty abacus. Although he didn't say how long it took him to install or boot the operating system, other forum users have chimed in and timed the installation for a Pentium III-based system at a low 17 continuous hours. And the boot time? 17 minutes.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
