Dan Tohatan - Windows 7: A Review

In 1994, Microsoft unveiled a user interface that was truly revolutionary at the time. Code-named "Cairo", it was to become the interface of the new Windows 95 operating system. When Windows 95 came along in July of 1995, the new shell (Windows Explorer) totally surpassed the old Program Manager / File Manager combination, which had been a staple of Windows since Windows 3.0. Windows 95's unparalleled multimedia capabilities became evident very quickly.

I remember how amazed I was when I first saw the Windows 95 boot-up screen, in all its 256-color beauty. Microsoft got it. The world was moving toward true color displays. No longer were UIs going to be boxed into the 16-color (or less) paradigm which had dominated displays since the 1980s. A revolution was beginning, and Windows 95 was going to lead it.

Fast-forward to the present, and a new revolution is beginning. This time, it's a move from bitmapped graphics to vector graphics. It's a move toward 3D-accelerated vector graphics. You can see it in the new Web 2.0 websites out there: smooth gradients, subtle 3D effects, animations, and heavy use of mouse-over events. You could call this the second UI revolution.

Windows Vista was supposed to bring in this new UI revolution. However, Microsoft bit off more than it could chew. Vista over-promised and under-delivered. The result was, as everyone now knows, a total disappointment. Today, almost 3 years after Vista's release, the market share held by Windows Vista is around 25%. The market share held by XP? 60%. What's even worse for Microsoft is that Mac OS X and Linux have been gaining feverishly thanks to Vista's lack of stability and incredibly slow performance.

Windows 7 is what Vista should have been. It is to Windows XP what Windows 95 was to Windows 3.1. I would encourage everyone reading this review to go out and download & install the Windows 7 Release Candidate. I have (so far) only used the OS for a day, and I am extremely impressed.

The most interesting thing about Windows 7 is that it's the first Windows OS to have lower system requirements compared to the previous version. While it has been demonstrated that Windows 7 can be installed on a system with only 512 MB RAM, it's not a realistic requirement if you want to run the latest applications. A system with 1 GB of RAM or more should be able to run Windows 7 at least as fast as it would run Windows XP. Also, while Windows 7 requires 16 GB of free disk space to install, it only ends up using about 9 GB, which is far better than Vista.

I'm going to start this review by looking under the hood - at how the OS performs. One of my biggest problems with Vista is the size of the WinSXS folder. Apparently, in order to solve "DLL hell", Microsoft decided to keep every single version of every DLL forever. Before I installed Windows 7, my Vista SP1 WinSXS folder was 7 GB, with no apps installed. This was after I ran the SP1 clean-up tool. Before that, it was over 10 GB. With Windows 7, it's only 4 GB. Seems MS was able to cut out a whole 3 GB from the WinSXS folder, which is excellent.

Another thing that MS improved with Windows 7 is the speed of shutdown. While boot-up is about the same as Windows Vista, shutdown is noticeably faster. Also, the speed of installation (if you're doing clean install) is much faster than a comparable Vista installation. I remember when I installed Vista that it seemed to take longer than an equivalent XP install. Windows 7 actually installs faster than XP.

I remember with Vista having issues with the TrustedInstaller. It would just start up randomly and my hard drive would start thrashing, and my system would slow to a crawl. Windows 7 seems much more quiet (in terms of hard disk activity) and CPU usage is actually at 0% most of the time! It's incredible how Windows 7 release candidate (not even final release) outperforms Vista so much. The final release will probably be even better.

Moving on to the UI, the first thing you notice about Windows 7 is how much cleaner it is compared to Vista. Gone are the incessant notification popups or the glaring UI inconsistencies that made Windows Vista such a pain to use. UAC is totally gone. In Vista, just about everything you did would pop up a UAC dialog. It was extremely annoying. In Windows 7, the UAC prompts, even where you would obviously expect them (e.g. Task Manager), are totally gone. It's a mystery what MS did here, but it's a really good thing. I really hope that this is permanent and that UAC doesn't come back in the final release.

The other pleasant surprise I had with Windows 7 was that MS added new accessories! This is the first time MS did something like this since (probably) Windows 95! Not only that, but the existing accessories (Wordpad, Paint) have been totally revamped. You will also notice the UI consistency in Windows 7 (versus Vista). Finally, I'm pleased to announce that MS has finally removed the "Install New Font" dialog that still had a Windows 3.0-like UI. This calls for a major celebration! This dialog existed in Windows - unchanged - since 1990! Now it's finally gone!

What I really like about Windows 7 is its new Libraries feature. A library is a special folder that is actually the aggregate of multiple folders. Libraries makes organizing files so much easier. Microsoft also implemented a fairly complete set of filters (or views) for each library. For example, you can view your music by artist or by album. The views are customized to fit each library type. For example, the Music library only has views that are relevant to music.

But it's the small things that make Windows 7 so impressive. For example, when copying files, the progress is shown in the taskbar as the background of the taskbar button, and it updates in real time. So you can just look at the taskbar to see the progress. You no longer have to Alt+Tab. Also, the extensive use of mouse-over effects really adds to the usability of the OS. For example, hovering over a taskbar button shows you a preview of the window that corresponds to that button.

Windows 7 is probably the first Windows OS for which screenshots aren't enough. This is because of the extensive use of mouse-over effects. Screenshots just don't do it justice. When I looked at various screenshots of Windows 7, I thought "what a bad UI design!" But in practice, the UI design is very usable. Not only is it usable - it's fun! This is the first time I'm having fun using Windows since Windows 95!

To conclude, you really have to use it to fully appreciate it. There are many pleasant surprises in this OS. When I switched to Ubuntu back in 2007, I never thought I'd see another version of Windows as great as Windows XP was. Well, it turns out I was wrong. Windows 7 is the new Windows 95. Windows XP was an evolutionary change. Windows 7 is a revolutionary change. Windows 7 leaves its competition in the dust. In the end, Microsoft still gets it.
