Windows 10 Windows 10 KB5048652 issue

After installing the Windows 10 KB5048652 update, my computer startup time went from less than 30 seconds to almost 3 minutes. The only thing that changed was the update. Anyone else have this issue?

Hi @drhubb,
The issue you're describing — significant slowdowns in startup time following the installation of the KB5048652 update — certainly indicates that something in this patch is affecting your system's boot process. You’re definitely not alone when it comes to Windows updates occasionally wreaking havoc on performance; similar complaints sometimes arise following cumulative updates.
Let me break down some possible causes and resolutions:

Possible Causes:​

1. Startup Conflicts:
   • The update might have enabled or altered certain startup programs or services. New components introduced in updates can sometimes register themselves to auto-start.
2. Driver Issues:
   • Some updates can clash with outdated or incompatible drivers, causing performance bottlenecks during startup.
3. Disk Optimization Pending:
   • After a major update, Windows often performs post-update tasks like indexing files or optimizing the disk, which can increase boot times temporarily.
4. Background Services:
   • It's possible that KB5048652 has introduced new background services or processes that increase the load during startup.
5. Corrupted Files:
   • System files or other components updated during the installation might have glitches, leading to inefficiencies.

Steps to Diagnose and Fix the Issue:​

1. Check Startup Programs:​

• Press Ctrl + Shift + Esc to open Task Manager.
• Go to the Startup tab and review the list:
  • Disable anything unnecessary by right-clicking and selecting "Disable". Ensure critical system processes are untouched.

2. Update Supporting Drivers:​

• Run Device Manager and update drivers for your key components, especially for:
  • Graphics card
  • Disk drives
  • Network adapters
  If you suspect driver issues, try rolling back any driver that was updated close to the time the update was installed.

3. Run Disk Cleanup:​

• Open the Start menu, type Disk Cleanup, and select it.
• Clean system files related to Windows Update (make sure to check "Windows Update Clean-up").

4. Assess Windows Services:​

• Open the Run dialog (Windows Key + R), type services.msc, and press Enter.
• Look for any services related to the update (these might include diagnostics or telemetry-related services) and try setting them to "Manual" for testing purposes.

5. Check for Pending Updates:​

• Sometimes, slowdowns are resolved after follow-up bug fixes issued by Microsoft:
  • Go to Settings > Update & Security > Windows Update.
  • Check for and install any additional updates.

6. Undo the Update (if necessary):​

If the problem persists and no acceptable workaround appears, consider rolling back the KB5048652 update:

• Open Settings > Update & Security > Windows Update.
• Select View update history > Uninstall updates.
• Locate KB5048652 and uninstall it to see if performance improves.
  Be sure to let Microsoft know via Feedback Hub if this resolves your issue, as it may signal a wider problem they need to address.

7. Log Analysis:​

A closer look at startup logs might help. Use Event Viewer:

• Open Start, type Event Viewer, and launch it.
• Navigate to Windows Logs > System, look for any errors or warnings during startup.

Temporary Workarounds:​

• Clean Boot:
  • Perform a clean boot (disable all startup items and non-Microsoft services) to isolate third-party conflicts:
  • Type msconfig in the Run dialog, go to the Services tab, check "Hide all Microsoft services", then disable the rest.
• Optimize Startup Settings:
  • If you're running an HDD, consider enabling Fast Startup in the Control Panel under Power Options > Choose what the power button does.

If these suggestions don't help, feel free to provide any additional symptoms or share logs — I’ll be glad to dive deeper into the problem! Let me know if you’ve noticed any other performance issues accompanying the startup delay.
