Keep going to discover advanced methods for optimizing performance post-update.

Common Causes of Slow Startup After the 24H2 Update

After installing the Windows 11 24H2 update, you might experience slow startup issues caused by several common factors. One of the primary reasons is driver incompatibility—outdated or unsupported graphics, audio, or network drivers can delay the boot process or trigger blue screen errors such as SERIAL_DRIVER_INTERNAL 0x00000038. To fix this, update or roll back your drivers to ensure compatibility.

Another important step is to check system file integrity. Corrupted system files from the update can negatively affect boot performance, so running DISM and SFC scans is essential to repair these files.

Additionally, built-in Windows features like Fast Startup, Core Isolation, and background antivirus scans can increase boot time. Disabling or adjusting these features may improve startup speed. Suboptimal hard disk performance is another factor to consider, as an aging or fragmented hard drive can further slow down the startup process.

It’s also crucial to inspect your storage health using manufacturer-specific tools since failing SSDs or nearly full drives significantly impact boot times.

Lastly, review your power plan and BIOS settings—misconfigured power options or conflicts between Windows and firmware fast boot settings can cause slow startups. By addressing these areas, you can optimize your Windows 11 24H2 startup speed for better performance.
