The description is correct regarding the main specifications (Intel Core i7-14700 processor, 32GB RAM, 512GB SSD, UHD Graphics 770). However, this model usually comes with Windows 11 Home pre-installed, according to the similar specifications of the Aspire XC series, which include a Windows 11 Home (64 Bit) operating system. It is therefore likely that an operating system is pre-installed, but for precise confirmation on this exact model (DT.BLSEG.00W), it is advisable to check with the vendor or manufacturer.
