Microsoft Corp. said that some personal computers will come pre-installed with Windows 10 at the time of the software’s release on July 29.
Dell Inc., Hewlett-Packard Co., Lenovo Group Ltd. and Acer Inc. will have machines with Windows 10 for sale in stores on the first day, Microsoft said in an e-mailed statement. The operating system, which most customers will get as a download for existing machines, isn’t totally complete yet and so the final version hasn’t been given to PC makers, the company said.
