Windows 11 Slow Startup? Here’s How to Speed It Up

A Windows 11 PC that takes minutes to start, freezes after login, or lags during startup is often slowed down by startup apps, outdated drivers, corrupted system files, an HDD, and more.

This post offers you the most effective solutions to speed it up. Let’s dive in!

Why Does Windows 11 Start Up Slowly?

Experiencing slow computer startup in Windows 11? It could be caused by:

• Too many startup programs: Multiple apps launching at startup compete for CPU and memory.
• Low memory: Limited RAM (4GB or less) forces Windows to use slower virtual memory.
• Low disk space: Insufficient free space can delay system processes.
• Outdated drivers: Old storage or graphics drivers can slow startup.
• Hardware bottlenecks: Traditional HDDs are slower than SSDs.
• Enhanced security features: Features like Core Isolation may slightly affect performance.

If your Windows 11 boots slowly, try the following methods to speed it up.

3. Right-click any app with High/Medium impact and select Disable.

Method 2. Turn off Fast Startup

Windows 11’s Fast Startup is intended to make your PC boot faster, but it can occasionally cause slow startup. If your system is affected, here’s how to turn off Fast Startup.

1. Search for Control Panel in the Windows Search bar and open it.
2. Go to Hardware and Sound > Power Options.
3. In the left-hand panel, click What do the power buttons do.
4. Click Change settings that are currently unavailable.
5. Uncheck the Turn on fast startup (recommended) checkbox.
6. Click Save changes.

Method 3. Update Windows and Drivers

Running an outdated Windows 11 system or graphics driver can cause slow startup and performance issues. Keeping Windows updated and updating your graphics driver can fix these issues.

Here’s how.

Method 5. Free up Disk Space

If your C drive is running out of space, the system will slow down file read speeds during startup.

To resolve this issue, it’s generally recommended to keep at least 15% to 20% of your system drive free.

To do that, you have two options:

• Delete temporary files to free up disk space.
• Extend the C partition to increase its space.

Option 1. Delete Temporary Files

Temporary files in Windows 11 can pile up over time, causing a slow startup. Removing these files can speed up your PC.

1. Go to Settings > System > Storage.
2. In the right panel of Storage, click the Temporary files category.
3. Check boxes to select files to remove, like the Recycle Bin and Downloads.
4. Click Remove files.

Option 2. Extend the C Partition

To extend the C partition, you can take free space from any other existing partitions or unallocated space. Then, MiniTool Partition Wizard’s Extend Partition feature can help you do that.

The steps are as follows:

1. On its main interface, highlight the C partition and select Extend Partition from the left action panel.
2. In the pop-up window, choose a partition or unallocated space from the drop-down list of Take Free Space from. Then drag the blue block to decide how much space to occupy. After that, click OK.
3. Click Apply to perform the pending operation.
4. Select Restart Now to allow the computer to restart. When your computer successfully restarts, you will find that the C drive has been extended.

Method 6. Check for Malware

Malware and viruses can infect your Windows 11 system via online downloads or data transfers.

These infections can corrupt files and cause slow boot times in windows 10/11.

To protect your PC, regularly scan for threats using Windows Defender or a trusted antivirus program. Follow these steps:

1. Go to Settings > Privacy & security > Windows Security.
2. Click Virus & threat protection from the right side.
3. Click Scan options, select Full scan, and then click Scan now.

Method 7. Turn off Memory Integrity

Core Isolation uses virtualization technology to enhance security. In some cases, it can impact performance. You can try disabling this feature to see if it resolves the Windows 11 slow boot.

1. Go to Settings > Privacy & Security > Windows Security Center > Device Security.
2. Click Core Isolation details.
3. If the Memory Integrity switch is on, turn it Off.
4. Restart your computer and check if the problem persists.

Method 8. Check for System Files

When system files are corrupted, your PC may experience slow boot times and reduced performance. Using DISM and SFC helps detect and fix these issues. Here’s how to do it:

1. Type cmd in the search bar, right-click Command Prompt, and then select Run as administrator.
2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This command will scan and repair corrupted Windows system components by replacing them with healthy ones.
3. After the DISM process finishes, type sfc /scannow and press Enter. This command will scan all protected system files and automatically repair any corrupted ones.

Method 9. Disable Visual Effects

Windows 11’s visual effects consume significant system resources. Disabling or reducing these effects can decrease CPU and memory load, thus shortening startup time.

1. Open Settings, then go to System.
2. Click About, then click Advanced system settings.
3. In the System Properties window, go to the Advanced tab, then click Settings under the Performance section.
4. Select Adjust for best performance to turn off everything, or choose Custom and uncheck specific visual effects.
5. Click Apply > OK.

Method 10. Increase RAM

If your PC has less than 4GB of RAM (8GB is recommended for modern Windows 11 performance), adding more memory can improve overall speed and boot times.

To check RAM usage, open Task Manager, go to the Performance tab, and click Memory. Here, you can see the RAM information, including the total and used memory.
