There can be various occasions when there arises the need to perform a Windows 7 clean install. Clean install simply means to install the Windows 7 on an unused partition on the computer’s hard drive. But sometimes you might find difficulty in performing the Windows 7 clean install because of the 0×80070057 error. This article will provide you technical support tips to resolve the error so that you can install Windows 7 in a hassle free manner.

A clean install of Windows 7 removes the existing Windows operating system, and then replaces it with a fresh copy of Windows 7. The best technique of performing the install is to wipe out your computer’s primary hard drive partition and then reinstall Windows 7 from the very scratch. People might require performing the install when they need to get rid of viruses, or when they are updating the computer’s operating system or when the OS gets corrupt. Thus, there can be various other reasons behind the need for clean installation.

In such a scenario, if the installation process gets stuck because of the error, then it is certainly irritating and anguishing.

The following technical support tips can help you in fixing the error.

Resolution for the error 0×80070057

To facilitate clean installation, it is important to resolve the error 0×80070057. The best computer support tip for troubleshooting this error is to delete the existing unused partition on your computer’s hard drive. If you don’t know how to perform the partition deleting, partition creation and formatting, then you continue reading the following online computer repair tips:

• First, insert the Windows 7 installation DVD
• Then start the installation
• Then, select your language preferences before setting the installation process
• Next, select the ‘Time’ and ‘Currency’ format
• Finally, select the Keyboard or input method options
• Then click ‘Next.’
• Next, click on ‘Install now.’
• On the next screen, you will view the Microsoft license agreement
• Here, click on ‘I accept the terms of license.’
• Then click ‘Next.’
• Click ‘Custom.’
• Now, select the ‘Disk 0 Partition 1.’
• Then click ‘Delete.’
• On the next prompt, click ‘OK.’
• Now, select ‘Disk 0 Partition 2.’
• Then click ‘Delete.’
• On the next prompt, click ‘OK.’
• Now, click ‘New.’
• On the next screen, select a size for the new partition disk.
• Then click ‘Apply.’
• If you leave the disk size to the default, then it will automatically pick up the maximum size of the disk.
• On the next prompt, click ‘OK.’
• Then, select ‘Disk 0 Partition 2.’
• And then click ‘Formatting.’
• On the next prompt, click ‘OK.’
• Wait for the formatting to get completed correctly.
• Now to continue further, click ‘Next.’

Conclusion

If you want to replace the older operating system with a fresh Windows 7 installation, then a clean install is certainly the best method. But error 0×80070057 may be an obstacle.

Once you perform the troubleshooting steps mentioned above, you must try performing the Windows install once again. This time the installation must get accomplished without creating an error.

If the error still prevails, then it is advisable that you call an online tech support firm and seek professional computer support services. It is quite understandable that people go for clean install only when it is extremely requisite. In such a situation, no one likes to get banged by a silly error. The troubleshooting method mentioned above must help you in getting rid of the error, otherwise avail online computer support.

Micro-Optics: Manufacturing, Testing and Characterization Processes

Micro-optics has opened up a new world of optics for people today. They are not just the basis of modern high-tech microelectronics, but are can successfully produce creative solutions by rightfully combining the traditional optical technologies with its modern counterpart. The manufacturing process of micro-optics includes advanced light use and cutting-edge optical features and functionality. This technology helps to create customized solutions to meet your customer requirements, easily and quickly.

There are companies that produce micro-optic products offering excellent performance and leveraging the state of the art fabrication technologies. These products help to meet specific needs of customers and covers fast and flexible prototyping to large-scale production of diffraction, refractive and hybrid micro-optics. Use of deep UV and long wave infrared is also noted.

One of the most popular manufacturing processes is wafer-based. It is a standard technology used in the semiconductor industry. Experts believe for manufacturing high-quality products, wafer-based microlens technology is most hopeful. It uses processes like resist coating, lithography, reactive ion etching, and more. You can use this technology to produce 10 microns to 2mm diameter as well as aspherical lens with outstanding uniformity and right lateral positions.

One of the main areas of concern for micro-optics part is the correct choice of manufacturing process. In addition, for testing, people must take special care. Due to small size of microlens openings, there is limitation of measurement accuracy by fringes number and sampling accuracy. However, the current scenario doesn’t offer proper testing and characterization. Testing equipment in the semiconductor industry or test equipment from traditional optical manufacturing is not suitable for these kind of products and services.

Wafer-based technology uses standard semiconductor rules and apparatus. Actually, the semiconductor industry is the leader with high amount of investment made in high-tech modern tools and apparatus. One of the prime benefits of manufacturing micro-optics is the use of all equipment that the semiconductor industry uses for its own needs. So it is quite cost-effective. Moreover, since all processes depend on standard technologies of the semiconductor industry, so quality has nothing to do with your budget.

However, one area of concern is the use of instruments for testing microlenses. It is still outdated and not developed for ensuring high quality and accuracy. For example, if you want to test interferometrical of small microlens you have to combine interferometer with a microscope for adequate magnifying of observed fringe patterns. If you want to test large microlenses, you need more advanced, fast equipment which is now unavailable. Since the micro-optics industry is still very new, this lack of adequate instruments is serving as a constraint to manufacturing, testing and characterization.

Research institutions or the manufacturing companies themselves develop most of test instruments that we use in the micro-optics industry these days. Since this industry is not yet popular, manufacturers built instruments in small quantity only. Therefore, the lack of instruments is a burning problem in this field. In the manufacturing phase, process optimization is directly dependent on the ability to measure products quality.
