The RemoteFX loss, FEC and retransmission gauges were not percentages. They exported the raw numerator of a Windows sample fraction, a running count that only grows.
The numerator and its base are now two counters. Get the ratio with `rate(windows_remote_fx_net_lost_packets_total[5m]) / rate(windows_remote_fx_net_loss_sampled_packets_total[5m])`, and likewise with `windows_remote_fx_net_fec_packets_total` / `windows_remote_fx_net_fec_sampled_packets_total` and `windows_remote_fx_net_retransmitted_packets_total` / `windows_remote_fx_net_retransmission_sampled_packets_total`.

- `windows_mssql_databases_xtp_controller_dlc_peak_latency_seconds`, `windows_mssql_dbreplica_database_flow_control_wait_seconds` and `windows_mssql_dbreplica_group_commit_stall_seconds` are now in seconds. SQL Server reports microseconds, which 0.31 did not convert correctly.
- `windows_mssql_locks_count` is no longer divided by 1000.
- `windows_ad_directory_operations_total{operation="write",origin="local_security_authority"}` now counts directory writes from the LSA. In 0.31 it repeated the LSA search count.
- `windows_ad_sam_computer_creation_requests_total` and `windows_ad_sam_computer_creation_successful_requests_total` were swapped in 0.31. Requests now count all attempts, successful requests only the successful ones.
- `windows_dhcp_denied_due_to_nonmatch_total` now counts denials due to a non-match. In 0.31 it repeated the match denial count.
- `windows_remote_fx_gfx_frames_skipped_insufficient_resource_total` with `resource="client"` and `resource="server"` now count the matching frames. In 0.31 the two label values were swapped.
- `windows_netframework_clrmemory_gc_time_percent` no longer overflows, and it is left out when Windows reports no base value. The `netframework` collector now reads the CLR counters through PDH instead of WMI; names, labels and types are unchanged.
