The Accounting department of the company has Windows XP installed in all of the computers. The accounting director of the department wants to upgrade the operating system Windows 7. The department would get certain benefits through an upgrade of the operating system that are discussed as follows.
First, the Windows 7 provides a great user-friendly interface for all the users to perform their desired tasks. The design of taskbar and system trays are much user-friendly compared to the Windows XP. However, anyone who was more comfortable with the Windows XP outlook can choose an option to change design of Windows 7 back to XP. Other interesting features that are most beneficial for the businesses are the desktop slideshow and screen savers. The accounting department users may activate the desktop slideshow to most recent financial statements and thus, keep a regular check. The bookkeeping and other accounting functions flourish with this feature of the Windows 7. Another big advantage of Windows 7 for not only the accounting department, but also all other departments is that, it runs smoothly with even 1GB memory. However, Windows 7 is available in two formats that is one for the 32-bit processor and the other with 64-bit processor. The 64-bit version of the Windows 7 requires 4GB RAM; however, the speed is quite higher; therefore, the accounting department can install various heavy accounting software programs and still work at a high speed processing with Windows 7 64-bit version. Windows 7 also provides better security features as compared to the Windows XP. Users can make different accounts with each one having high-level security permissions. The upgraded Windows Office and Open Office programs provide great features for the accounts users. Like, there are large number of financial formulas and functions, now available in the MS Excel. These programs assist the accounts users in bookkeeping, payroll processing, Balance Sheets, printing paychecks, and income statement.
At the Dart’s company, the accounting department may come across the problem of hardware, if it has small sized RAM, as Windows 7 requires at least 1 GB RAM. Moreover, it is bit difficult to upgrade the system installed with XP to Windows 7. Usually the professionals do not find any problem when they switch from Windows XP to Windows 7; however, it may difficult for the new users to get accustomed with Windows 7 easily. The accounting department may face compatibility issues with certain software programs as well.
Yes, the 16-bit billing program that was designed for the Windows XP can run on the Windows 7 OS 32-bit version. For this purpose, the user would have to choose the program and right click for the choice of compatibility under Windows XP or earlier versions. The program may not be able to run direct using the Windows 7 platform, but Windows 7 provides an interface to run the program. However, the users face major problems, when try to run the 16-bit billing software program on the Windows 7 OS 64-bit version.
Currently, the Darts Company’s marketing department is using MAC OS X version 10.4 Tiger Computers for its daily operations. The company is planning to upgrade the systems of the department; however, advance version of only MAC system can be deployed. It is because; the programs would only be compatible with Apple products. Several benefits can be achieved with an upgrade of MAC OS X 10.4 system to an advanced system like MAC OS X 10.6. For example, an upgraded version of the system provides better security, reliability, ease of use, and compatibility of MAC OS X version with Windows as well. With better reliability and security, Darts Company’s marketing department would ensure protection of the users’ data and other confidential information. As like, accounting department, the latest version of the system offers user-friendly medium and is compatible with most of the Windows programs. Thus, marketing department users of the Darts Company would easily be able to share information with the Windows 7 users and run windows 7 programs on the MAC OS X 10.6 .
The reason of processor overloading might be due to certain viruses like svchost.exe that consumes all of the power and can take the CPU usage up to 100% even if no heavier or simple is running on the system. Such behavior of the system shows that the processor is being affected by the viruses. The overloading or any other problem with the processor can be determined through task manager in Windows Vista. To resolve such kind of issues, the user must install an antivirus program that can identify and kill the viruses, malware, and spyware .
Although Windows 7 is too new as compared to Windows Vista, but still Windows 7 is much easier to manage and use than Windows Vista. Therefore, not to make choice of Windows 7 due to being latest in the operating systems can be exempted. Several new features have been added to the Windows 7 in comparison to the Windows Vista. Moreover, Windows 7 provides better interface for the users than Vista. Windows 7 is highly efficient, when requires running heavy-duty applications. It offers great speed and performance as compared to Vista. Furthermore, in view of financial terms, Windows 7 is still a better choice than Vista. It is because; the prices of Windows 7 is less than all other Windows operating systems. Only one issue with the Windows 7 is that, it requires time to upgrade from Windows XP. Still, upgrading from Windows XP to Windows 7 cost lesser than Windows Vista; therefore, it would be a better choice to upgrade all of the Windows XP systems in the organization to Windows 7 instead of Vista .

The desktop computers running on the AMD Duron CPU would only require upgrading the processor of higher speed. To upgrade the desktop computer running on the Pentium 4 CPU, it would only need to upgrade the motherboard; however, if the processor seems powerful then there is no need to replace it in the Pentium 4 CPU. Finally, to upgrade the desktop computers running on Intel Core Duo CPU, it would require upgrading RAM, motherboard, and graphics card; however, the processors can be kept as it is, but this strategy would increase the cost. It is recommended to install the entire new systems in place of Intel Core Duo CPU.
It may happen either due to hardware problems, cabling, corrupted software program, or due to overheating of the system hardware. It is suggested to keep on checking the CPU temperature, and if high temperature were the issue, then the systems would require keeping them in the lower temperature area. Furthermore, it is recommended to replace certain hardware equipment in the system like cards, RAM, and motherboard. This would raise the price of the upgrade; therefore, it is recommended to replace the entire Intel Core Duo CPU. Intel has launched various new versions of the CPU with the same core duo series.
