About this tag
Compatibility shims are targeted workarounds applied by Windows to resolve issues with older hardware or software without requiring changes to the original code. On WindowsForum.com, discussions cover how Microsoft uses a secret compatibility table in the Bluetooth stack to fix a 2006 mouse's name encoding problem, and how Secure Boot certificate rollovers may require shims to maintain boot-level compatibility. A developer profile highlights the Windows Compatibility team's work in creating shims to solve customer-reported problems, often involving low-level assembly code. These threads illustrate how compatibility shims help bridge the gap between legacy components and modern Windows systems.
