Windows 11 Slow to Boot? 9 Ways to Speed Up Startup (2026 Guide)

Did your Windows 11 PC take several minutes to reach the desktop, get stuck on the loading screen, or feel unusually slow every time you turn it on? Slow startup times can be caused by too many startup apps, outdated drivers, disk errors, corrupted system files, or hardware issues such as an aging hard drive. The exact solution depends on what’s causing the delay. In this guide, you’ll learn how to find what’s slowing down your Windows 11 startup and follow practical fixes to reduce boot time and get your PC ready faster.

Why Is Windows 11 Taking So Long to Start?

When you turn on your PC, Windows loads system files, drivers, background services, and apps configured to run automatically. If any of these take too long to load or encounter problems, your PC may take longer than usual to reach the desktop.

Some common reasons why Windows 11 PC is slow to start include:

• Too many startup apps: Programs that launch automatically when you turn on your PC can increase boot time and use system resources in the background.
• Outdated or faulty drivers: Problems with graphics, storage, or other hardware drivers can delay startup.
• Windows system file issues: Corrupted or missing system files can prevent Windows from loading efficiently.
• Low storage space: A nearly full drive can affect overall system performance, including startup speed.
• Background services and updates: Windows updates, security software, and other services may temporarily slow down startup.
• Older hardware: Traditional hard drives (HDDs), limited RAM, or aging components can make Windows 11 take longer to boot.

Method 1: Disable Unnecessary Startup Apps

Every time you start your PC, Windows automatically launches certain applications in the background. While some startup programs are essential, many third-party apps, such as chat clients, cloud storage services, game launchers, and update utilities, can increase boot time and slow startup.

Disabling unnecessary startup apps can reduce startup time without affecting their normal operation. You can still open these apps manually whenever you need them.

To disable startup apps in Windows 11:

1. Right-click the Start button and select Task Manager.
2. Click Startup apps from the left sidebar.
3. Review the list of applications and check their Startup impact to identify apps that have a high impact on boot time.
4. Right-click any app you don’t need to start automatically and select Disable.
5. Restart your PC and check whether the boot time has improved.

Tip: Leave security software, hardware drivers, and touchpad or audio utilities enabled. Disable only apps that you recognize and don’t need immediately after signing in.

Method 2: Install Windows and Driver Updates

Outdated Windows components or incompatible device drivers can slow down the startup process by delaying how Windows initializes hardware during boot. This is especially common after a major Windows update or when storage, chipset, or graphics drivers become outdated. Installing the latest Windows updates and drivers can fix known bugs, improve hardware compatibility, and reduce startup delays.

Update Windows

1. Open Settings and select Windows Update.
2. Click Check for updates.
3. Download and install any available updates.
4. Restart your PC if prompted.

Update Device Drivers

If your PC is still slow to boot after installing Windows updates, check whether newer device drivers are available.

You can update drivers using one of these methods:

• Windows Update (recommended for most users)
• Device Manager
• Your PC or motherboard manufacturer’s support website

Focus on updating these drivers first:

• Storage controller (SATA/NVMe) – Affects how quickly Windows accesses your system drive during startup.
• Chipset – Helps Windows communicate efficiently with your motherboard and connected hardware.
• Graphics – Can resolve delays during the loading of the Windows sign-in screen and desktop.
• Network adapter – Update this if startup becomes slow after signing in or while connecting to the network.

After installing the latest updates, restart your PC and check whether Windows boots faster.

Tip: If the slow boot problem started immediately after a Windows or driver update, consider uninstalling the recent update or rolling back the affected driver to see if it resolves the issue.

Method 3: Check and Repair Disk Errors

Disk errors can slow down the Windows startup process by delaying access to important system files. These issues may occur after an unexpected shutdown, power failure, or improper system restart. Windows includes built-in tools that can scan your drive for errors and repair them.

Option 1: Use Error Checking

1. Open File Explorer and select This PC.
2. Right-click your Windows drive (usually C:) and select Properties.
3. Open the Tools tab.
4. Under Error checking, click Check.
5. Follow the on-screen instructions to scan and repair any detected errors.
6. Restart your PC and check whether the boot time has improved.

Option 2: Run CHKDSK

Run CHKDSK only if you suspect drive errors, such as frequent freezes, file corruption, or unexpected shutdowns.

1. Search for Command Prompt, then select Run as administrator.
2. Type the following command and press Enter:

chkdsk C: /f

3. If prompted, type Y to schedule the scan the next time your PC restarts.
4. Restart your computer and allow CHKDSK to complete the scan.

Note: The scan may take some time depending on the size and condition of your drive. Avoid interrupting the process once it starts.

Method 4: Repair Corrupted System Files (SFC & DISM)

Corrupted or missing system files can prevent Windows from loading properly, resulting in longer boot times, startup errors, or an unresponsive desktop. Windows includes two built-in tools, System File Checker (SFC) and Deployment Image Servicing and Management (DISM), that can scan and repair damaged system files.

Step 1: Run System File Checker command

1. Search for Command Prompt, then select Run as administrator.
2. Type the following command and press Enter:

sfc /scannow

3. Wait for the scan to complete. If corrupted system files are found, Windows will attempt to repair them automatically.
4. Restart your PC after the scan finishes.

Step 2: Run DISM RestoreHealth command

If SFC reports that it couldn’t repair some files or your PC is still slow to boot, run the DISM command to repair the Windows system image.

DISM /Online /Cleanup-Image /RestoreHealth

After DISM finishes, restart your computer and run sfc /scannow again to verify that all system files have been repaired.

Tip: These scans can take several minutes to complete. Keep your PC connected to power and avoid closing the Command Prompt until the process finishes.

Method 5: Free Up Disk Space

Windows needs free storage space to manage temporary files, install updates, and optimize system performance. If your system drive is nearly full, your PC may take longer to boot and feel less responsive after signing in.

For the best performance, try to keep at least 15–20% of your system drive free.

Delete Temporary Files

• Open Settings and go to System > Storage.
• Click Temporary files.
• Select the items you want to remove, such as temporary files, Windows Update cleanup, and the Recycle Bin.
• Click Remove files.

Uninstall Unused Apps

1. Open Settings > Apps > Installed apps.
2. Review the list of installed programs.
3. Uninstall applications you no longer use to free up storage space.

In addition, move large files such as videos and photos to another drive or cloud storage.

Enable Storage Sense

Storage Sense automatically removes temporary files and empties the Recycle Bin to help keep your drive from filling up.

1. Go to Settings > System > Storage.
2. Turn on Storage Sense.
3. Configure it to automatically clean temporary files.

After freeing up disk space, restart your computer and check whether Windows boots faster.

Method 6: Try Disabling Fast Startup

Fast Startup is a Windows feature that reduces boot time by saving part of the system state when you shut down your PC. While it works well on many computers, it can sometimes cause slow startup, boot loops, or other startup issues, particularly after Windows or driver updates.

If your PC recently became slow to boot, disabling Fast Startup is worth trying.

Here’s how to disable Fast Startup:

1. Open Control Panel and select Power Options.
2. Click Choose what the power buttons do.
3. Select Change settings that are currently unavailable.
4. Under Shutdown settings, clear the Turn on fast startup (recommended) checkbox.
5. Click Save changes.
6. Restart your computer and check whether the boot time has improved.

Tip: If disabling Fast Startup doesn’t make a difference, you can re-enable it later using the same steps.

Method 7: Scan Your PC for Malware

Malware, viruses, and other unwanted software can consume system resources and add background processes that slow down Windows startup. Running a security scan can help detect and remove threats that may be affecting your PC’s boot performance.

Scan with Windows Security

1. Open Settings and go to Privacy & security > Windows Security.
2. Click Virus & threat protection.
3. Select Scan options.
4. Choose Full scan, then click Scan now.
5. Wait for the scan to finish and follow any recommended actions.

If Windows Security detects malware, remove or quarantine the threats, then restart your computer and check whether the startup time has improved.

Tip: If you use a trusted third-party antivirus program, make sure it’s updated before running a full system scan.

Method 8: Perform a Clean Boot

If Windows still boots slowly after trying the previous solutions, a third-party application or service may be interfering with the startup process. Performing a Clean Boot starts Windows with only essential Microsoft services, making it easier to identify whether background software is causing the delay.

Here’s how to perform a Clean Boot:

1. Press Win + R, type msconfig, and press Enter.
2. Open the Services tab.
3. Check Hide all Microsoft services.
4. Click Disable all.
5. Switch to the Startup tab and click Open Task Manager.
6. Disable all unnecessary startup applications.
7. Close Task Manager, click OK, and restart your PC.

If Windows starts much faster in a Clean Boot state, one of the disabled services or startup applications is likely responsible. Re-enable them one at a time until you identify the program causing the slow startup.

Note: Once you’ve finished troubleshooting, open System Configuration (msconfig) again and choose Normal startup to restore your usual startup settings.

Method 9: Upgrade Your Hardware

If you’ve tried all the previous solutions and Windows 11 still takes a long time to boot, your hardware may be limiting performance. Upgrading older components can significantly reduce startup time and improve your PC’s overall responsiveness.

Upgrade to an SSD

If your computer still uses a traditional hard disk drive (HDD), upgrading to a solid-state drive (SSD) is one of the most effective ways to improve Windows 11 boot time. SSDs are much faster than HDDs, allowing Windows to start quicker, applications to load faster, and your PC to feel more responsive overall.

If your hard drive is showing signs of failure, such as frequent disk errors, unusual noises, repeated freezes, or bad sectors, back up your important files immediately. When replacing the drive, choose an SSD instead of another HDD for better performance and reliability.

Add More RAM

If your PC has 4 GB or 8 GB of RAM, adding more memory can improve startup performance, especially if multiple applications and background services load when Windows starts. While upgrading RAM won’t reduce boot time as much as an SSD, it can make your computer more responsive after you sign in.

Tip: If your PC still has an HDD, upgrading to an SSD should be your first priority. It provides the biggest improvement in boot speed and overall system performance compared to any other hardware upgrade.
