There are two versions of Internet Explorer 10 in Windows 8—a Metro app and a desktop app. Both share the same rendering engine and, unsurprisingly, perform identically on the same hardware. The only difference is UI, and the fact that Metro’s IE will not run plug-ins like Adobe Flash or Microsoft’s own Silverlight.

To reflect the distinction between the Metro version of IE and the desktop version, both Metro and the desktop retain separate default browser settings—you can run Firefox or Chrome as your default browser on the desktop and stick with IE in Metro, but you can also specify desktop browsers as the default Metro browser, meaning that links clicked in Metro apps like Mail will dump you to the desktop to open rather than stay in the Metro interface. Oddly, if you decide not to use IE as your default Metro browser, the IE completely disappears from Metro, and it takes a trip into the desktop Internet Settings control panel to re-enable it.

The Metro version of IE is a minimalist, touch-centric affair—the address bar is located at the bottom of the screen, and will disappear from view when it’s not being used. While typing in the address bar, IE will display a tiled list of your most frequently visited sites, as well as sites that you have “pinned” using the address bar’s pin button—these pinned sites will also show up on the Start screen. The address bar also has the requisite Back, Forward, and Refresh buttons, as well as a Tools button that will let you search the current page or open the page in the desktop version of IE (the desktop version contains no such button to open pages in Metro mode, at least for now).

The most consistent way to bring up the address bar on a PC is by using the Windows + Z keyboard shortcut that we discussed earlier, which will also bring up Metro IE’s tab interface, which displays big, clickable thumbnails of all your open tabs. You can also open new tabs, clean up your tabs (which closes all but the active tab), or open a new InPrivate browsing tab, which is clearly marked with a blue “InPrivate” icon.

The desktop version of IE looks more or less like IE9, though of course the UI hasn’t necessarily been finalized at this point. One of the only noticeable differences is the presence of a Metro-style scrollbar on pages that require one. Also new is an “Install new versions automatically” checkbox in the About Internet Explorer page, reinforcing Microsoft’s desire to get and keep Windows users on the most current IE version their operating system supports. There’s no evidence that Microsoft plans to move to the rapid-release cycle that Google and Mozilla have both adopted (such a decision would give enterprise IT managers apoplexy), but this sort of functionality would theoretically make it possible.

Benchmarks

Now, let’s peek under the hood and get a few performance numbers. According to these basic tests, IE10 is faster than IE9 by a noticeable margin, but it can’t quite catch up to the current versions of Firefox or Chrome. These benchmarks were all run on the Dell Latitude E6410 that served as my main Windows 8 machine for this review.

Kraken JavaScript Benchmark 1.1

v8 JavaScript Benchmark v6

Interestingly, all browsers performed the v8 benchmark slightly faster in Windows 8. The difference isn’t huge—just a few hundred points in both cases—but it is both consistent and measureable, and I thought it interesting that the OS update slightly improved the performance of these third-party programs. Kraken scores were consistent across Windows 7 and Windows 8.

    Seriously? I do not want either of those things.

    Please tell me that these are artifacts of running Windows 8 on a system with an underpowered graphics card, or at least that the rounded corners and "glass" effects simply have not been built in to the preview version.

    Square windows here to stay, not a big deal. Windows borders can get more or less opaque depending on your settings, just like in 7.

    Maybe not a big deal, objectively speaking, but it feels like a step backwards to me. Between that and Metro I'm seriously considering just sticking with Windows 7. It does everything I need in a way that I like, with no trade-offs being made to support touch-based devices (which my desktop isn't).

    I'm starting to get the feeling that Microsoft could have another "XP vs. Vista" debacle on its hands, no? Back then I switched to Vista but never really felt that it was a significant improvement until Windows 7 came around. I didn't hate Vista or think that it was worse than XP the way a lot of people seemed to, but I wasn't really thrilled with it either. Windows 7 was an unquestionable improvement over both Vista and XP, however.

    Perhaps this time I'll stick with "legacy" Windows 7 until Windows 9 comes out.

    Totally possible! Especially so in businesses, which move more slowly and are only now rolling 7 out over XP.

    The rounded vs. square corners thing is a matter of taste, I guess. It does seem to be showing up everywhere - Lion killed rounded buttons in favor of squared ones too. It's not important to me, but I suppose it is a little "old-school." :-)

    Every new OS simply needs an option to use the old UI. That would take away the fundamental reason why users don't want newer OS's.

    I refuse to use anything beyond XP. Vista's and 7's Explorer is less functional, and other various UI functionality is different for the worse. Likewise, IE7/8/9 have a topbar that lacks real functionality and can't be customized, unlike IE6.

    Here are a couple of oddities I've noticed:
    * Start screen... If you try scrolling horizontally with a touchpad, absolutely nothing happens. In the developer preview, I had to read online to find out why the danged thing wouldn't scroll.

    * Split-up search sucks.
    Try this in Windows 7: Windows key -> "featu". So long as you don't have, say, "bluetooth feature pack" installed, you can just press enter to get to "Programs and Features".
    Try it in Windows 8: Windows key -> Featu. Down, down, enter, enter. 4 key presses required to replace the original 'enter'.

    * Start screen, another thing to try: Windows 7: search for something, then press the "context menu" key on the keyboard. You should get the right-click menu of the highlighted item. Windows 8: you get the right-click menu for the textbox you're typing in!

    * The boot process seems weird on my Intel 320 SSD. After the initial disk activity, it sits there doing apparently nothing (no disk activity) for over 30 seconds. Effective boot time is around 60 seconds, not including POST. For comparison, resuming from hibernate to the login screen takes only about 4 seconds.

    * You ever try it on a pen-only (Wacom) Tablet PC? It's worse than a mouse, because it seems to actively disable the screen corner gestures -- they don't work with the pen OR the touchpad on that system.

    Now, for a nifty thing to try: right-click in the lower-left corner of the screen.

    Fixed that error on page 3 for you:

    "..Microsoft insists that the PC is just another kind of tablet..."
  • vivekgarg79 - Monday, March 12, 2012 - link

    I have x86 (32 bit) m/c. I want to develop metro UI app, using VS2011 for windows 8. Will VS 2011 (x86) work on top of Windows 8 consumer preview (x86)??
  • haplo602 - Monday, March 12, 2012 - link

    I read the first 3 pages, then skipped to the conclusion. I realised I don't give a damn about any new Windows/Tiles version. Happy Linux camper since Windows XP.

    The UI change will be a big jump. It will be interesting to see the outcome.
  • iwod - Monday, March 12, 2012 - link

    I couldn't believe how positive this review was, from a technical user prospective.

    And it surely prove M$ has little to no understanding of how UI should be designed. There is now Metro, and a half baked Desktop environment. I can see more user jumping on to Mac platform when Windows 8 comes out.

    I think the root of all wrong doings; Tablet is just another PC. Which is where it all goes wrong.

    P.S - I have been forcing Metro on myself for week now. I can definitely say it "could" be a great Tablet OS. Desktop? I will pass.
