Solution 3: Manual Update Installation

• 🧐 If the above steps fail, identify the specific problematic update (Windows update or driver update) in Settings > Windows Update.
• 🔍 For driver updates, use Device Manager to find the hardware ID of the problematic device.
• 🌐 Search for the hardware ID on the Microsoft Update Catalog website (catalog.update.microsoft.com).
