Gonin / Getty Iimages Microsoft last week released to corporate customers a preview of the next pay-once, perpetual license version of its Office suite. The application bundle — by far the productivity standard in business — came with a mouth-twisting name change: Office LTSC Professional Plus 2021. As it did in February when it revealed some information about the successor to Office 2019, Microsoft again argued that the new suite is a limited-use option for enterprises. "The next perpetual version of Office for commercial customers is built specifically for organizations running regulated devices that cannot accept feature updates for years at a time, process control devices that are not connected to the Internet in manufacturing facilities, and specialty systems that must stay locked in time and require a long-term servicing channel," the Microsoft 365 team wrote in an April 22 post to a company blog.
