Role: This is the heart of the system. If is hasn’t be protected well, unimaginable consequences will caused. When the virus is trying to write something to the system, it will be failed if there is no sufficient authority. Of course, this will also cause some programs cannot be installed successfully. It requires you to manually set back the total control permission in administrators and system. After the installation is finished, change back that setting.

Tips for Troubleshooting DLL Errors

Follow the steps below:-

Step #1: Run a malware scan

Did you know malware infection is a common cause of recurring DLL errors, such as the msvcr80.dll error?

Malware programs are known to alter the codes embedded in DLL files. As a result, a DLL error occurs when another program or process calls upon the infected DLL file.

If you are experiencing recurring DLL errors, run a malware scan to check if this is not the case on your computer.

Step #2: Uninstall and Reinstall the application with you are getting the DLL error

Are you getting a DLL error only with a particular application?

If you just said YES, then chances are either the DLL file listed in the error message is missing or corrupt, or there is some problem with one or more application files.

To fix the matter, uninstall and reinstall the application.

Similarly, if you have started receiving the DLL error after you have uninstalled a program then reinstall it and check if the error is fixed. The reason why we are saying this is because at times shared DLLs are also removed while uninstalling a program. This leads to the situation when another programs calls upon the deleted shared DLL file but the system is unable to locate it and thus returns a DLL error.

Step #3: Update your Windows, software, and driver files

When was the last time you installed Windows updates or for that matter updated your software and device drivers?

If your answer is, “Can’t remember,” then chances are your files are outdated. Outdated files can various problems, including DLL errors.

To automatically install new Windows updates keep the built-in Automatic Update feature enabled (this useful feature was first introduced with Windows ME and since then has been an integral part of Windows).

Many third-party software have a built-in update feature. Use it to keep your software files up-to-date. If the feature is not present in some software, then install the new updates manually from the software manufacturer’s website.

You can update your driver files either manually by visiting the driver manufacturer’s website (this approach can be time-consuming) or use a reliable driver update tool to have your drivers automatically updated.

Step #4: Perform System Restore

If the DLL error persists, restore your system to a prior date when you were not receiving the error.

Step #5: Clean your registry

Issues in the registry can lead to various errors, including DLL errors. If you have not cleaned your registry before, its time you scanned your registry using advanced registry maintenance software to get rid of all the redundant and incorrect registry entries.

Perform the steps illustrated above to fix and prevent DLL errors and improve performance of your Windows computer.

Documents Folder Opens At Windows Startup

The answer is a corrupted registry entry.

Run regedit and navigate to:

HKLM/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon


In there there should be a value (on right hand side of screen) called Userinit.

The data for this value is probably something similar to:

C:\windows\system32\userinit.exe,C:\windows\system32\userinit.exe,

If you do see a duplicated string in there similar to the above - simply double click on the Userinit value and edit the data so as to delete everything to the right of the first comma (,). In the case above you would leave only:

C:\windows\system32\userinit.exe,

Exit registry edit and reboot. No more My Documents!

A look at Windows 7 Graphical user interface

The most distinguishing feature about the Windows 7 is its Graphical user interface which is very fantastic. It carries all the positive aspects of Vista, along with the core infrastructure of the operating system. But the interface has been made more user friendly. The international features of Windows 7 are pervasive throughout the system, from low-level aspects as the supported characters in NTFS file names (now upgraded to match Unicode 5.1) to such high-level aspects as the selection of backgrounds and themes.

Windows Aero is the graphical user interface and the default theme in most editions of Windows Vista and Windows 7. It is also available in Windows Server 2008. The diction Aero in itself means Authentic, Energetic, Reflective and Open. Intended to be a cleaner, more powerful, more efficient and more aesthetically pleasing user interface than the previously used theme (Luna). Windows 7 includes new translucency, live thumbnails, live icons, animations and eye candy. Aero also encompasses a set of user interface design guidelines for Microsoft Windows.

The mind of a man is always reflected whether he speaks or not. Windows 7 gives opportunity to personalize the computer the way a person wants. Windows 7 has increased opportunities for personalization. New themes, backgrounds, and sounds make it easy to customize Windows 7 to match your personality. To the extent that our preferences are influenced by our language and location, Windows 7 reflects this with the introduction of Local Packs. Local Packs provide customized Windows 7 visual themes for a specific region. These visual themes contain locally relevant wallpaper images, custom aero glass colors, and regional sound schemes. The best easy way is changing the wallpaper. All OS vendors provide an easy way to customize it. Windows 7use personal photos, stock photography or even rotate set of images. As a result the OS GUI designers have no way to predicting the wallpaper color or image palette.

Fancy background colors can be very distracting. A logical move for designer would be to isolate a user form potentially distracting desktop environment so that they can focus on task on hand. MS decides not to do that and introduce transparent windows instead. On top of that they blur content underneath the window (making it very clear how hard it is to use a computer if you can’t find your glasses). Similar experiment were carried by Apple a year ago. They tried to introduce a transparent tiny bar on top of the screen and had to leave making this feature optional due to user complains.

Evidently, the need for patches is a symbol of weak design structure and of logic flaws in the original design. Not only the GUI design. Any design in general (not to be confused with ”art”). Good design tends to achieve the maximum with the minimum. Each design is a structure or set of rules based on a certain logic - physical or abstract. For example we can look at a chair as a set of physical rules. If your design requires you to introduce a 5th leg and then in turn 2 small legs to support that 5th then you may want to start from the beginning and rethink the original concept. GUI design is no exception.

The Aero feature has been revised in a much better way in Windows 7. Several touch-friendly UI and many new visual effects and features has been introduced.

Let's have a review of it:-

* Aero Peek - hovering over a taskbar icon shows thumbnail of that program. Hovering over the thumbnail shows a preview of that program in full view. Aero Peek also refers to the "Show desktop" button to the far right of the new taskbar.

* Aero Shake -You may have opened several Windows but at a time you need single to work. You can use this feature to minimize all other windows by just dragging the single window back and forth. Shaking it again brings other windows back.

* Aero Snap - Clicking and dragging a window to the right or left side of the desktop causes the window to fill the respective half of the screen. Snapping a window to the top of the desktop maximizes it. Resizing a window to touch the top or bottom edge of the screen maximizes the window to full height, whilst retaining its width; these windows will then slide horizontally if moved by the title bar, or can be pulled off, which returns the window to its original height.

* Touch UI - Windows 7 is more touch-friendly. For example, the title bar buttons are now slightly bigger.

* Maximized windows remain glass instead of becoming opaque.

* When hovering over the taskbar button for a running program, the button glows the dominant RGB color of its icon. Also, a shiny effect follows the mouse as it is moved across the icon of active programs.

* When moving windows, the CPU and GPU load is minimized by limiting the frame rate that the Aero part is rendered so as to provide better performance to applications.

* Windows 7 shows more blending blur effect in Aero than on Windows Vista.
