Windows Slow Startup can make even a good PC feel old. You press the power button, wait through the boot screen, sign in, and then wait again while apps load in the background.
Most startup problems come from simple causes: too many startup apps, low storage, pending updates, old drivers, background services, or a drive that is struggling.
Before you reset Windows or blame your hardware, check these fixes first.
Why Windows Slow Startup Happens
A slow startup usually means Windows is doing too much before the PC is ready.
Microsoft notes that Windows performance can be affected by limited storage, too many startup apps, outdated software, and hardware limits in its official guide on improving PC performance in Windows.
That matches what many users see in real life. The PC does not only load Windows. It also loads cloud apps, launchers, security tools, update services, drivers, and background processes.
The goal is not to disable everything. The goal is to stop unnecessary things from slowing down boot.
1. Disable Startup Apps You Don’t Need
Startup apps are one of the most common reasons Windows takes too long to become usable.
Some apps need to start with Windows, like security software or touchpad utilities. Others do not. Game launchers, chat apps, update helpers, cloud tools, and hardware control apps can often wait until you open them manually.
On Windows 11:
- Open Settings.
- Go to Apps.
- Select Startup.
- Turn off apps you do not need immediately after boot.
You can also use Task Manager and check the Startup apps section.
Focus on apps marked with high startup impact. Disable one or two at a time, then restart and test.
2. Check Fast Startup Settings
Fast Startup is designed to help Windows boot faster by saving part of the system state during shutdown.
It helps on some PCs, but it can cause problems on others. If your PC hangs at startup, takes too long after signing in, or behaves strangely after shutdown, testing Fast Startup is worth it.
To check it:
- Open Control Panel.
- Go to Power Options.
- Select Choose what the power buttons do.
- Select Change settings that are currently unavailable.
- Turn Fast Startup off or on, then restart.
If startup improves after disabling it, keep it off. If nothing changes, you can turn it back on.
This is a test, not a guaranteed fix.
3. Free Up Storage Space
Windows needs free storage to work smoothly.
When your main drive is almost full, startup can slow down because Windows has less room for temporary files, updates, caching, and background tasks.
Start with the built-in Storage settings. Microsoft’s guide on Storage Sense explains how Windows can remove temporary files and help manage drive space automatically.
Check these first:
- Temporary files
- Recycle Bin
- Old downloads
- Large videos
- Unused apps
- Old installation files
Try to keep enough free space on your Windows drive, especially if it is a smaller SSD.
4. Install Pending Windows Updates
Pending updates can make startup feel slower.
Windows may finish update tasks during shutdown, restart, or login. If updates keep failing, the PC may repeat the same work again and again.
Go to Settings, then Windows Update. Install available updates and restart when required.
Also check optional driver updates carefully. Do not install every optional driver blindly, but if a storage, chipset, or graphics driver is clearly outdated, it may help with startup and general stability.
If your PC became slow right after an update, give it some time. Windows may need a few restarts to finish background optimization.
5. Scan for Malware and Suspicious Apps
Malware can slow startup by loading unwanted processes, browser helpers, fake security tools, or background services.
Even if you are careful, it is worth running a scan if startup suddenly becomes slow.
Microsoft explains the difference between quick scans and full scans in its antivirus and antimalware FAQ. A quick scan checks common hiding places, while a full scan takes longer but checks more files.
Open Windows Security and run a scan. Then uninstall apps you do not recognize or no longer trust.
Be especially careful with “PC cleaner” tools that promise instant speed. Some add more background activity than they remove.
6. Update Drivers That Affect Boot
Drivers help Windows communicate with your hardware. Bad or outdated drivers can slow startup, especially storage, chipset, graphics, Wi-Fi, and Bluetooth drivers.
You do not need to chase every driver update online. Start with:
- Windows Update
- Your PC manufacturer’s support page
- Your motherboard manufacturer’s support page
- Your laptop support app, if it is from the manufacturer
Avoid random driver updater websites. They can install the wrong drivers or unwanted software.
If your PC started booting slowly after a new driver, roll it back from Device Manager or uninstall the recent update if needed.

7. Check Background Services Carefully
Some background services are necessary. Others come from apps you installed and forgot.
If Windows feels slow after login, the problem may not be the boot itself. It may be the first minute after login, when background services start running.
Open Task Manager and check the Processes tab right after startup. Look for apps using high CPU, disk, or memory.
Common causes include:
- Cloud sync tools
- Game launchers
- RGB control software
- Printer utilities
- Update agents
- Backup tools
Do not disable random Windows services unless you know what they do. Start with apps you installed yourself.
8. Check Your Drive Health
If your PC still has a hard drive, slow startup is expected compared with an SSD.
But even an SSD can cause slow boot if it is nearly full, failing, or connected incorrectly. If startup became slow suddenly and apps also open slowly, check the drive.
Warning signs include:
- Clicking noises from a hard drive
- Freezes during boot
- Very slow file copying
- Disk usage stuck at 100%
- Errors during updates
- Random blue screens
If your system drive is old, back up important files before trying deeper fixes.

Quick Windows Slow Startup Checklist
Try these in order:
- Disable unnecessary startup apps.
- Restart and test boot time.
- Free up storage space.
- Install pending Windows updates.
- Run a malware scan.
- Test Fast Startup on or off.
- Update key drivers from trusted sources.
- Check Task Manager after login.
- Review background apps and services.
- Back up files if the drive may be failing.
Do not change everything at once. Make one or two changes, restart, then check if startup improves.
When a Reset Might Be Worth It
A reset should not be your first fix.
But it may help if Windows has years of old apps, broken drivers, failed updates, and background tools that are hard to clean manually.
Before resetting, back up your files. Also save license keys, browser bookmarks, work files, and app installers.
If the PC is very old or still uses a hard drive, upgrading to an SSD may improve startup more than any setting change.
Final Thoughts
Windows Slow Startup is usually fixable without extreme steps.
Start with startup apps, storage space, updates, malware scans, Fast Startup, and drivers. These are the areas most likely to slow boot without making the PC look obviously broken.
If startup becomes faster after removing one app or changing one setting, you have found the problem. If nothing helps and the PC freezes during boot, check drive health before the issue becomes data loss.
FAQ
Why is Windows startup so slow?
Windows startup is often slow because too many apps load at boot, storage is low, updates are pending, drivers are outdated, malware is running, or the system drive is struggling.
How do I stop apps from opening on startup?
Go to Settings, then Apps, then Startup. Turn off apps you do not need immediately after signing in. You can also manage startup apps from Task Manager.
Should I turn off Fast Startup?
Try it if your PC is slow, stuck, or unstable during startup. Fast Startup helps some PCs but causes issues on others. Test both settings and keep the one that works better.
Can low storage make Windows boot slower?
Yes. Low storage can slow Windows because the system needs space for temporary files, updates, caching, and background tasks.
Can malware cause Windows Slow Startup?
Yes. Malware and unwanted apps can load at startup and use CPU, disk, memory, or network resources in the background.
What is the fastest way to improve startup time?
Disable unnecessary startup apps first. It is simple, safe, and often makes the biggest difference without changing important system settings.
