Windows Seven:Features Compared
Hetty Maddock
Windows 7 is the successor of Windows Vista and its version name is Windows NT 6.1, compared to Vista's NT 6.0. Its naming caused some confusion when it was announced in 2008.[17] Windows president Steven Sinofsky commented that Windows 95 was the fourth version of Windows, but Windows 7 counts up from Windows NT 4.0 as it is a descendant of NT.[18]
The taskbar has seen the biggest visual changes, where the old Quick Launch toolbar has been replaced with the ability to pin applications to the taskbar. Buttons for pinned applications are integrated with the task buttons. These buttons also enable Jump Lists to allow easy access to common tasks, and files frequently used with specific applications.[67] The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the Show desktop icon. By default, hovering over this button makes all visible windows transparent for a quick look at the desktop.[68] In touch-enabled displays such as touch screens, tablet PCs, etc., this button is slightly (8 pixels) wider in order to accommodate being pressed by a finger.[69] Clicking this button minimizes all windows, and clicking it a second time restores them.
Window management in Windows 7 has several new features: Aero Snap maximizes a window when it is dragged to the top, left, or right of the screen.[70] Dragging windows to the left or right edges of the screen allows users to snap software windows to either side of the screen, such that the windows take up half the screen. When a user moves windows that were snapped or maximized using Snap, the system restores their previous state. Snap functions can also be triggered with keyboard shortcuts. Aero Shake hides all inactive windows when the active window's title bar is dragged back and forth rapidly.
Given the way Windows operating systems evolve over their lifecycles, it is impossible right now to overly praise or damn Windows 10 but we can start drawing conclusions compared to the differences between it and its predecessors.
In addition to this, the performance is usually better on Windows 10 thanks to all sorts of software optimizations, although Windows 7 is actually not that far behind. Still, sudden FPS drops and micro-stutters can be a problem in online gaming. Windows 7 also uses more RAM compared to Windows 10, which makes the latter better in this respect. In general, new games run faster on Windows 10, even though the difference seems rather minimal.
With this Blog I would like to provide some general information on the lifecycle of this release as well as information on the new features coming with 7.70. Since the new features contained in 7.70 are quite complex compared to previous releases, I also mention additional prerequisites and potential consequences of each feature.
Synopsis: Windows that enable the PERPIXEL_TRANSLUCENT kind of transparency by means of setting a non-opaque background color may not display heavyweight (e.g. AWT) child components correctly. AWT supports lightweight (e.g. Swing) components in per-pixel translucent windows only. More information on the difference between the two kinds of components can be found in the Component class specification and in the Mixing Heavyweight and Lightweight Components article.
Synopsis: Translucent windows support has been added to AWT. Before enabling visual effects by invoking the Windows.setOpacity(), Windows.setShape(), or Windows.setBackground() methods, a developer should verify whether the desired effects are supported. This is done by invoking the GraphicsDevice.isWindowTranslucencySupported() method and specifying the desired effect as an argument. If the method reports an effect as supported, enabling it won't throw an exception. However, there are several issues when using the effects on X11 systems (Linux, Solaris).
- Per-pixel translucency (Windows.setBackground()): while the effect may be reported as supported, windows with this effect enabled may not look transparent visually because the system isn't running any compositing manager. The system should either be running a compositing window manager (such as compiz), or a separate compositing manager (such as the xcompmgr). Unfortunately, there is no way to detect whether a compositing manager is currently running, so Java is unable to report whether the transparent window will actually appear transparent. It can only check and report that enabling the effect for a window is supported by the native platform.
- Simple translucency (Window.setOpacity()): the effect may be reported as unavailable in Java, while the window manager actually supports it for active applications and is able to display semi-transparent windows. This happens because a window manager (e.g. some versions of Metacity) doesn't report the effect as supported. Please note that this is not a defect in Java, but rather a bug in the window manager. More details are available in CR 6762511.
One of the main differences between Windows 7 and Windows 11 is how the operating system prioritizes application windows. While both systems are optimized for performance, Windows 11 utilizes foreground processes to load apps faster.

- Get fully functional taskbar with Start menu and system tray on each monitor
- Quickly move windows between monitors
- Set its own wallpaper and screensaver on each monitor
- Play a game on one monitor and chat, surf web, etc. on others
- Connect as many monitors as you need (up to 64 monitors supported)
Actual Multiple Monitors improves Windows user interface when working with several monitors at once. Install Actual Multiple Monitors to get such essential controls as Taskbar, Start menu, system tray and Task Switcher on each connected display, quickly allocate windows between monitors (either manually or automatically), improve the look-and-feel of your desktop with the multi-monitor desktop wallpaper and screen saver, switch your laptop between internal display and external displays in a click with desktop profiles. Play your favorite games on one monitor and chat, serf web, stream online video, etc. on the others at the same time without fear that the game will minimize.
With these subtle but indispensable enhancements your productivity may be increased several times!
If you find ExecuteCommandLists substantially more expensive compared to Windows 10, it has to do with how many resources you have resident at the time of the call: On WDDM1.x (as found on Windows 7), the driver is responsible for submitting allocation lists with ever command buffer submission, which the kernel will iterate over and make sure they are resident before allowing that work to execute. In D3D12 on Windows 7, the driver generates this allocation list based on the set of resources that are currently resident at the time of submission. The cost you are seeing is a per-allocation cost, which can be quite high; the size of the allocation is irrelevant here.
We compared root proliferation in fertilized microsites among seven cultivars of five commonly planted cool-desert perennial grass species that differ in productivity and competitive ability. In a greenhouse experiment on nutrient-limited plants, one soil microsite in each pot received distilled water (control) and a second microsite received a rich, complete nutrient solution (fertilized). Roots in and adjacent to the microsites were mapped on Mylar windows for 22 days after the injections to determine the magnitude and timing of response in root length relative growth rates (RGRs). Because we provided adequate water, used a high level of fertilization in the treatment microsites, and conducted the experiments during rapid vegetative growth, the results provide a measure of the relative capacities and maximal rates of the grasses responses to enriched microsites. Root samples were harvested from control and fertilized microsites at the end of the experiment to determine the morphological basis of the proliferation response. In all seven grasses fine roots proliferated in the fertilized microsites faster than in the control microsites. The grasses did not differ in the timing of their response which showed a peak 7-8 days after injection. Although one species, Pseudoroegneria spicata cv. Goldar, had higher maximum root length RGR and higher RGR ratio (RGR in fertilized to RGR in control microsites) 7-8 days after injection, the seven grasses did not differ significantly in the magnitude of root length RGR response to fertilizer integrated over the 22 day experiment. The grasses also did not differ significantly in root morphological changes in fertilized mocrosites. Compared to roots in control microsites, roots in fertilized microsites had greater specific root length, length of secondary roots per length of main axis, number of lateral and sublateral roots per length of main axis, and mean lateral root length. Root proliferation was mainly the result of increased lateral branching and lateral root growth in all seven grasses. The consistency of root proliferation responses among these seven cultivars suggests that differences in the capacity for, maximum rate, or morphological basis of root proliferation are not directly related to ecological characteristics such as productivity and competitive ability. Other aspects of root response to nutrient enrichment, such as differential responses as a function of microsite nutrient concentration, plant phenology, plant nutrient status, or specific nutrient element(s), may still be important, but further experiments are required to determine whether different responses to enriched soil microsites among species correspond with know species differences in ecological characteristics.
