Microsoft which has worked on shifting its customer base to a software subscription model will this year release two new standalone versions of its flagship Office productivity suite, the company announced. Jared Spataro, the company's vice-president in charge of the Microsoft 365 offering, said a commercial preview of Office Long Term Servicing Channel aimed at enterprise customers will be released in April this year. The LTSC version follows Office 2019, which was announced in 2017 and released in 2018, and which was expected to be the last, standalone "perpetual licence" version that can be installed on a single computer only.
