Microsoft started rolling out the upcoming Windows 10 May 2020 Update to Insiders in the Release Preview ring earlier this month. While that build was expected to be the final build, the Windows maker has just released another build to make some last-minute fixes and calls it the new final build. This build was earlier released to the Slow ring Insiders.

"While we originally thought that Build 19041.207 would be the final build, we made the decision to take in one more fix we felt was important to have before making the May 2020 Update generally available," the company writes. "We believe that Build 19041.208 is the new final build and still plan on continuing to improve the overall experience of the May 2020 Update on customers’ PCs as part of our normal servicing cadence."
