Why does the Start menu open faster than my actual programs?

That difference happens because the Start menu is a pre-cached, lightweight shell component that Windows keeps loaded directly in your system memory (RAM). When you launch actual programs, the operating system has to physically read dense data from your storage drive, unpack library files, and initialize background threads, which takes significantly longer if something is bottlenecking your disk or CPU.

If software launch times have suddenly tanked while the core desktop UI stays snappy, you can usually clear the slowdown with a couple of direct optimization adjustments:

1. Clean up stale background handles by disabling unnecessary startup apps. Open your Task Manager (Ctrl + Shift + Esc), click over to the Startup Apps tab, right-click any non-essential software or third-party launchers, and select Disable.

2. Run a native drive trim and health optimization pass to clear out physical read blocks. Open your Start menu, type Defragment and Optimize Drives, select your primary OS drive, and click the Optimize button to refresh the file indexing layers.

3. Clear out cached system bottleneck loops by executing a clean system storage purge. Tap the Windows Key + R, type cleanmgr, hit Enter, select your main drive, check the boxes for Temporary Files and DirectX Shader Cache, and click OK to wipe the clutter.

Trimming down those background startup elements and refreshing your drive's indexing paths usually gets application launch speeds back to normal. Hopefully, clearing those local cache layers unjams the bottleneck so your apps open up instantly again.
