Microsoft had promised that 2026 would be the year of reliability for Windows 11. Update KB5083631 is starting to prove the optimists right.
For several months, Windows 11 users in dark mode have been familiar with the blinding white flash that appears when opening File Explorer. A kind of digital flashbang, and not the kind that comes from Counter Strike 2 or Warzone. At the same time, the background update service was gorging on RAM without ever returning it. The applications starting up took their time. The optional update KB5083631deployed on April 30 for Windows 11 24H2 and 25H2, addresses these irritants. Focus on the fixes.

File Explorer stops blinding you
In Dark Mode, opening “This PC” or resizing the Details pane caused a white flash before the theme loaded. The discrepancy came from an unsteady cohabitation between the old legacy components and the new WinUI 3 interface. KB5083631 synchronizes the two layers, and the effect disappears.
Microsoft took the opportunity to correct another well-known annoyance. Folder display and sorting preferences evaporated as soon as a third-party application opened a directory directly. When Edge sent to the Downloads folder, Windows politely forgot your settings (large icons, sort by date, whatever). This is now fixed.

The explorer.exe process no longer remains active in the background like a silent squatter after all windows are closed. Ghost processes that were chewing up CPU have been eliminated.
30-year-old formatting limit skipped
The tastiest fix in this update has nothing to do with RAM. Since 1994, Windows has limited FAT32 formatting to 32 Go. Dave Plummer, a former Microsoft developer, imposed this restriction one rainy day while porting the Windows 95 interface to NT. A temporary choice, which became permanent through simple inertia over three decades…
KB5083631 raises this limit to 2 TB on command line. The graphical interface remains stuck at 32 GB for the moment. But for those who format USB keys or SD cards for a console, a car radio or a camera, the gain is concrete. The FAT32 file system, introduced with Windows 95 OSR2 in 1996, already supported these capabilities (third-party tools had been proving this for years). Windows simply refused to do it itself.
The update also fixes recurring Microsoft Store errors (codes 0x80070057 and 0x80073d28). A bug that erased Windows Hello biometric data after a major update also disappears. Remote Desktop display issues on multi-screen configurations have also been fixed.
KB5083631 remains optional for now. Those who prefer to wait will receive these fixes with the Patch Tuesday du 12 maimandatory update.
