How to download the image file from Microsoft website or other sources

Once you have a product key for Windows 8.1 Pro, you can download the image file from Microsoft website or other sources.

To download the image file from Microsoft website, you can follow these steps:

• Go to the official Microsoft download page for Windows 8.1 here.

• Enter your product key and click Next.

• Select your language and click Confirm.

• Choose whether you want to download the 32-bit or 64-bit version of Windows 8.1 Pro and click the corresponding button.

• Save the image file (ISO) to your computer.

To download the image file from other sources, you can use a torrent client or a direct download link from a reputable website. However, be careful of malware and viruses that might be attached to the file. Always scan the file with an antivirus program before opening it.

How to verify the integrity of the image file

After downloading the image file, it is recommended that you verify its integrity to make sure that it is not corrupted or tampered with. You can do this by comparing its checksum with the official checksum provided by Microsoft or the source website.

A checksum is a string of numbers and letters that is generated by applying a mathematical algorithm to a file. It serves as a unique identifier and fingerprint of the file. If two files have the same checksum, they are identical. If they have different checksums, they are different.

To verify the integrity of the image file, you can follow these steps:

• Find out the checksum of the image file that you downloaded. You can use a tool such as HashCalc or MD5 & SHA Checksum Utility to calculate the checksum of any file on your computer.

• Find out the official checksum of the image file that you should have downloaded. You can find it on the Microsoft website or the source website where you downloaded the file from.

• Compare the two checksums and see if they match. If they match, the image file is valid and intact. If they don't match, the image file is corrupted or modified and you should download it again from a reliable source.
