## Affected Systems
- Products: Windows 10
- Versions: Systems that have installed the KB5062554 update.
- Configurations: Standard Windows 10 installations using the built-in emoji panel ($\text{Win} + \text{.”}$).
## Vulnerability Description
The Windows 10 update identified as KB5062554 introduces a regression error that breaks the search functionality within the operating system's emoji panel. Users attempting to use the search feature in the emoji panel receive a generic error message stating, "We couldn't find this one," regardless of the search term entered.

- Complexity: Not Applicable
- Attack Vector: Not Applicable
## Impact
- Confidentiality: Minimal (Indirectly, potential minor user friction if using secure input methods that rely on this feature).
- Integrity: None
- Availability: Low (Affects the usability of the emoji panel search feature.)
## Remediation
### Patches
- Microsoft is expected to fix this bug in future monthly updates, though confirmation is pending.
- **Note:** Since Windows 10 reaches End of Support on October 14, 2025, Microsoft may prioritize pushing users to upgrade to Windows 11 rather than issuing immediate fixes for older systems.
### Workarounds
- Users must currently rely on manually browsing the emoji categories within the panel instead of using the search function.
## Detection
- **Indicators of Compromise:** N/A
- **Detection Methods and Tools:** Manual testing of the $\text{Win} + \text{.”}$ shortcut followed by typing any character into the search bar and observing if the "We couldn't find this one" error appears.
