It is true that Microsoft do not offer a free service for downloading their software products. The only official way is to pay a lot of money to register a MSDN subscription account at present. In fact, it’s not necessarily so. You can absolutely get any version of Microsoft Office/Windows OS from download sites on the Internet. However, the issue is how to make sure files are safe before downloading them. Fortunately, you can easily verify the Windows/Office ISO files using SHA-1 hash. This method makes sure that the downloaded files are intact and original.
After a time, I have collected all Microsoft Office/Windows OS versions and uploaded them to my cloud drive. The following is my list. You can click the file name to launch download in a new tab.
Microsoft Office Professional Plus
Windows OS Professional edition
*NOTE:* If you don’t know how to check the file integrity using its SHA1 hash, please read this post.
