Improvements and fixes in Windows 11 builds 26200.7628 and 26100.7628

The file system is the main focus of this update. Work has been done to fix a conflict that occurred after the January 13 patcheswhich caused several applications to freeze or have unexpected crashes. When trying to open or save documents on cloud storage platforms, especially Dropbox and OneDrive, this error occurred.

Microsoft Outlook was one of the most affected elements. The program could stop working completely on computers that stored data files (PST) in OneDrivewhich forced the user to reboot the system to gain access again. Likewise, errors in the handling of emails have been corrected to avoid the loss of shipments or the repeated downloading of old messages.
