Hello Eduardo Gnann,
I understand that after resetting Windows 11, your mouse pointer changed to an older Windows 98-style cursor. This behavior matches a known issue affecting Windows 11 24H2 and 25H2; it is still under investigation, and no fix date has been announced.
Please note that this is a user-to-user forum, moderators and contributors, including external Microsoft employees, cannot directly change product features or access Microsoft’s back-end systems. Our role is limited to sharing technical guidance based on available information and experience.
If you are experiencing this issue, or a similar issue, please use Feedback Hub to file a report. The Feedback Hub can be opened anytime by pressing the Windows key and "F" while in the Windows environment. For additional information, see Send feedback to Microsoft with the Feedback Hub app. Your reports are helpful to the investigation. An update will be provided in Windows 11 release health page when more information is available.
Thank you so much for your patience and your understanding!
