rangerequest

The rangerequest tag on WindowsForum.com covers issues related to the Windows Update feature that allows downloading only changed portions of update files. In the context of upgrading from Windows 21H2 to 24H2, errors such as 'IsRangeRequestSupported failed' and 'Setting RangeRequestSupported to FALSE' appear in setupact.log, indicating that the update process cannot use range requests. This failure can block upgrades without providing a clear reason. Discussions focus on troubleshooting these specific error codes and understanding how range request support affects Windows update reliability.
