Microsoft patches misrendered Remote Desktop warnings on multi-monitor PCs
Microsoft fixed a bug that caused the new Remote Desktop security warning dialog to render incorrectly on multi‑monitor setups after the April 2026 updates; the fix is in the optional Windows 11 KB5083631 preview (with 34 other changes). The issue affected Windows 11/10/Server and could make the warning dialog’s buttons unreadable or non‑interactive; it aligns with the standard RDP warning flow shown when opening preconfigured .rdp files. Separately, KB5083769 caused a VSS timeout that affected some backup apps on Windows 11 24H2/25H2, prompting out‑of‑band server fixes after the April updates.
