Slow startup in Windows 10 version 22H2 following the October 2023 update is often caused by driver conflicts, corrupted system files, or aggressive fast boot settings. You can resolve this by running the System File Checker, disabling Fast Startup, and updating device drivers to ensure a quicker boot process.
Diagnosing the Root Cause
The October 2023 cumulative updates for Windows 10 22H2 introduced changes that can interact poorly with certain hardware configurations or third-party software. Before applying fixes, it is crucial to understand what is delaying your boot sequence. The most common culprits include outdated storage drivers, conflicting startup applications, and the "Fast Startup" feature which sometimes fails to hibernate the kernel correctly after an update. To pinpoint the issue, check your Event Viewer for errors logged during shutdown or startup. Look for critical events related to disk I/O delays or driver timeouts. If you recently installed new hardware or updated graphics drivers, these are likely suspects. Additionally, if your system hangs at the manufacturer logo for more than thirty seconds, the delay is occurring before Windows even loads its core services, pointing towards BIOS/UEFI or hardware initialization issues rather than software bloat. For users experiencing broader instability alongside slow boots, reviewing general troubleshooting steps can provide additional context on system health. See our guide on Troubleshooting Windows 10 Software: A Comprehensive Guide for deeper diagnostic techniques.Disable Fast Startup
Fast Startup is a hybrid shutdown state designed to speed up subsequent boots by saving the kernel session to disk. However, after major updates like the October 2023 patch, this feature can cause significant delays if the saved state becomes corrupted or incompatible with updated drivers. Disabling it forces a full cold boot every time, which resolves many post-update slowdowns. To turn off Fast Startup, follow these steps:- Open the Control Panel and navigate to Hardware and Sound > Power Options.
- Click on Choose what the power buttons do from the left sidebar.
- Select Change settings that are currently unavailable to reveal administrative options.
- Uncheck the box next to Turn on fast startup (recommended).
- Click Save changes and restart your computer to test the improvement.
Run System File Checker and DISM
Corrupted system files are a frequent cause of performance degradation after updates. Windows includes built-in tools to detect and repair these issues automatically. The System File Checker (SFC) scans protected system files and replaces incorrect versions with correct Microsoft ones. The Deployment Image Servicing and Management (DISM) tool repairs the Windows image itself, which SFC relies on. Open Command Prompt as an administrator by right-clicking the Start button and selecting Terminal (Admin) or Command Prompt (Admin). Run the following commands sequentially:dism /online /cleanup-image /restorehealth
sfc /scannowUpdate Device Drivers
Driver conflicts, especially with storage controllers and chipsets, are primary reasons for slow initialization in Windows 10 22H2. Manufacturers often release patches specifically addressing compatibility with recent Windows updates. Outdated NVMe SSD drivers or RAID controllers can cause the system to hang while waiting for device readiness during boot. Visit your motherboard or laptop manufacturer’s support page to download the latest chipset and storage drivers. Alternatively, use Windows Update to check for optional driver updates. In the Settings app, go to Update & Security > Windows Update > Advanced options > Optional updates. Install any listed driver updates, particularly those related to storage or BIOS, and reboot. If you encounter issues with other system components during troubleshooting, such as stuck updates, refer to Windows Update Stuck at 73% - How to Fix it for similar resolution strategies.Clean Boot and Startup Apps
Third-party applications often register themselves to run at startup, consuming CPU and disk resources before you even log in. After an update, some of these apps may fail to load properly, causing delays. Performing a clean boot helps isolate these software conflicts. PressWin + R, type msconfig, and press Enter. In the System Configuration window, go to the Services tab, check Hide Microsoft services, and then click Disable all. Next, switch to the Startup tab and open Task Manager to disable non-essential startup items. Restart your computer. If the boot speed improves, re-enable services and startup items one by one to identify the specific offender.
Frequently Asked Questions
Why does my PC take so long to shut down?
A slow shutdown is often linked to the same Fast Startup feature that causes slow boots. When Fast Startup is enabled, Windows attempts to save the current session to a hibernation file, which can fail if drivers conflict. Disabling Fast Startup ensures a complete shutdown, often speeding up the entire power cycle process.
Should I reset my PC if the update broke my boot speed?
Resetting is a last resort. Most slowdowns are caused by driver or configuration issues rather than deep system corruption. Try the SFC scan, driver updates, and Fast Startup toggle first. Only consider a reset if these methods fail and the system remains unusably slow, as it erases personal data and apps.
Does SSD health affect boot times after updates?
Yes, a failing SSD or one nearing capacity can significantly slow down read/write operations during boot. Check your drive health using tools like CrystalDiskInfo. If your SSD has high write amplification or low remaining life, replacing it may be necessary regardless of Windows updates.
Can antivirus software cause slow startups?
Real-time scanning and scheduled tasks in third-party antivirus programs can delay boot times. These programs often hook into the startup process to scan files immediately. Temporarily disabling real-time protection or switching to a lighter security suite can help determine if your antivirus is the bottleneck.
What if my BIOS needs updating too?
Outdated BIOS versions can have poor compatibility with newer OS kernels or hardware states introduced in updates like 22H2. Check your manufacturer’s website for BIOS updates. Flashing the BIOS can resolve hardware initialization hangs that occur before Windows loads, though this carries higher risk and requires careful adherence to instructions.
