Additional images of Windows 8′s new taskbar leaked this week.

Microsoft’s Windows 8 taskbar images first leaked earlier this month but additional images surfaced over the weekend. My Digital Life forum user Vlad62 posted new images on Saturday. The new images further detail Microsoft’s Windows Live account integration directly into the Windows 8 Shell. The software giant has also provided several wallpapers with a “ssh…lets’ not leak our hard work” written on them and the latest images feature these. The future Windows Server image also appears to reveal an enhanced Windows Classic UI (see below).

Microsoft may be preparing to demonstrate its Windows 8 Tablet UI as early as June, according to reports earlier this month. Microsoft has a habit of introducing new technologies at the Wall Street Journal’s D: All Things Digital Conference, which will run from May 31 to June 2 this year. Bill Gates introduced Microsoft’s Surface computer in 2007 and the company demonstrated Windows 7 multitouch in 2008. It’s possible that Microsoft might be planning to demonstrate a technology preview of Windows 8 Tablets at the conference this year.

Microsoft may introduce Windows 8 ARM based tablets ahead of a full desktop release according to recent reports. Microsoft’s competitive tablet strategy is believed to be further along than expected. Dell’s recently leaked Tablet Roadmap revealed that the OEM has marked Q1 2012 as its date for a Windows 8 based slate. WinRumors understands that Microsoft has been working on an ARM based version of Windows for nearly a year and that it is laboring hard to bring this to the market as soon as possible. Microsoft has previously promised a “major revamp” of Windows for slate applications, that will come in the next version, Windows 8.

Microsoft has so far been extremely quiet on the Windows 8 front. Windows Chief, Steven Sinofsky, took to the stage at the Consumer Electronics Show in Las Vegas in January to introduce a technology preview of Microsoft’s Windows ARM support and show off an early build of Windows 8. Microsoft is partnering with ARM-based manufactures NVIDIA, Qualcomm and Texas Instruments to produce new Tablet devices. Rumors suggest that Microsoft will create a dual-UI for Windows 8.

Steve Ballmer has described the next release of Windows as the company’s “riskiest product bet”. Ballmer also recently claimed that Windows will change in future versions. It is understood that Microsoft will feature deep cloud integration into the future OS to realise its vision of “three screens and a cloud”. One Microsoft employee recently said he believes Windows 8 will be the “most important Windows ever shipped.”
