Installing KB3093266 cumulative update could stop Windows 10 from showing critical error dialogs in future. Microsoft has pushed cumulative update KB3093266 for Windows 10 and is available to download via Windows Update. As usual, this update has been offered to users without any changelog.
Finally some good news! Microsoft employee said on reditt that this update includes improvements to users having issues with start menu reliability or critical error dialog.
Windows 10 Cumulative Update KB3093266
“This update contains more improvements for anyone who’s been seeing issues with start menu reliability or the critical error dialogs mentioning start and/or Cortana – def jump on it if you’re one of those impacted.
Team continues to actively investigate other underlying causes for these issues, we appreciate your patience.”
Microsoft implemented Critical Error dialog fixes first on 10547 build, then they pushed those to Windows 10 stable
FYI, current insider build 10547 already contains that fix. “We have fixed a lot of the underlying causes of the critical error dialog Insiders were seeing with Start. “
We’ve said, it’s a matter of time for the software giant to push those fixes through an update for Winows 10 users on 10240 build, that’s what happened. KB3093266 has been delivered.
If you’re still having issues with Start menu and Cortana after installing this update, you may need to wait for some more updates.
