Why does my laptop take a long time to restart on Windows and how to fix it?

You clicked “Restart”, but instead of a quick restart, the system freezes on the logo Windows or a black screen for several minutes? Laptop rebooting slowly is a common problem that can occur on both older devices with HDD, and on new ones SSD. The reasons lie in system settings, hardware faults or software conflicts.

In this article we will look at 7 proven methods speed up reboots, from basic (cleaning startup) to advanced (checking the integrity of system files). You'll learn how to diagnose the problem using built-in tools Windows 10/11, which services can be disabled without risking stability, and when you should think about replacing your hard drive. We will pay special attention hidden power settings, which in 60% of cases are to blame for long reboots on laptops.

1. Check startup: programs that slow down the system

The most common reason for a long reboot is background processes, which do not have time to complete correctly. Many programs (especially antiviruses, instant messengers and cloud services) are added to startup and continue to work even when the PC is turned off. This increases the wait time for the session to close.

To check startup:

• 🔍 Open Task Manager (Ctrl+Shift+Esc) → tab Autoload.
• 📊 Sort programs by column Impact on launch (high/medium).
• ❌ Disable unnecessary applications (for example, Steam, Discord, OneDrive).
• ⚠️ Do not disable device drivers (for example, NVIDIA Telemetry or Realtek Audio) - this can lead to failures.

After disabling unnecessary programs, restart the laptop and note the time. If the difference is noticeable, the problem was with startup. If not, we move on.

2. Optimize Windows services: what can be disabled safely

Windows Services - These are background processes that run along with the system. Some of them are responsible for updates, diagnostics or synchronization, but not all are critical. Disabling unnecessary services can reduce reboot times by 20–40%.

How to do it:

• 🛠️ Click Win + R, enter services.msc and press Enter.
• 🔎 Find services with status Works and startup type Automatically.
• ⚙️ Double click on the service → in the field Startup type select Manually or Disabled.

Which services can be disabled (for most users):

Service name	Description	Risk of disconnection
Superfetch (SysMain)	Caches frequently used programs	Low (may be slightly slower when programs first launch)
Windows Search	Indexes files for quick search	Medium (PC search will be slower)
DiagTrack (Connected User Experiences and Telemetry)	Collects data for Microsoft	Absent (does not affect system operation)
Windows Update Medic Service	Restores update components	High (may break updates)

⚠️ Attention: Do not disable services with names DCOM Server, Plug and Play or Windows Audio - this will lead to critical failures.

3. Check your hard drive for errors and fragmentation

If your laptop is equipped HDD (not SSD), slow reboot may be due to disk fragmentation or bad sectors. Even on SSD Sometimes there are problems with the controller that slow down the reading/writing of system files.

How to check the disk:

1. 🖥️ Open This computer → right-click on the system disk (C:) → Properties → Service → Checking for errors.
2. 🔄 Click Check and wait for the scan to finish (may take up to 30 minutes).
3. 📊 For defragmentation (only for HDD!) use the command in CMD on behalf of the administrator:

   defrag C: /O /U

If the scan reveals errors that could not be corrected, this may indicate physical wear of the disk. In this case, it is recommended to transfer the system to a new one SSD - this will speed up the reboot by 3-5 times.

4. Power settings: why the laptop “falls asleep” instead of rebooting

Many users do not know that hybrid shutdown mode (enabled by default Windows 10/11) may simulate a reboot, but actually just saves the system state to a hibernation file. This saves time when turning on, but lengthens the actual reboot process.

How to disable hybrid mode:

• ⚡ Go to Control Panel → Power Options → What the Power Buttons Do.
• 🔓 Click Change settings that are currently unavailable.
• ❌ Uncheck Enable Fast Startup and save the changes.

Also check your power plan:

• 🔋 In the same section, select a scheme High performance (if available).
• ⚙️ Click Set up power plan → Change advanced settings.
• 📉 Set the parameter PCI Express → Link Status in Power Mode meaning Maximum performance.

⚠️ Warning: Disabling fast startup may increase the time inclusion laptop, but will reduce time reboot. It's okay.

What is hybrid shutdown mode?

Hybrid mode combines shutdown and hibernation functions: the system saves the OS kernel and drivers to a file hiberfil.sys, but closes user programs. When you turn on the PC, only the kernel is restored, which speeds up startup, but may conflict with a full reboot, especially if drivers or system components are being updated.

5. Windows updates: why they slow down reboots

Windows 10/11 often installs updates in the background, but final phase of applying changes Happens exactly when rebooting. If the system has not been updated for a long time, this process may take up to 10–15 minutes. Even worse, some updates (eg. KB502xxx) are known for bugs that cause freezes.

How to check and fix:

• 🔄 Go to Settings → Update & Security → Windows Update.
• 📥 Click Checking for updates and wait for completion.
• 🔧 If the updates are stuck, reset the components using the command CMD (administrator):

  net stop wuauserv
  net stop cryptSvc
  net stop bits
  net stop msiserver
  ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
  ren C:\Windows\System32\catroot2 catroot2.old
  net start wuauserv
  net start cryptSvc
  net start bits
  net start msiserver

If after updates the reboot still takes a long time, try roll back the problematic update:

1. 📋B Control Panel → Programs → Programs and Features → View installed updates.
2. 🗑️ Find the latest update (by date), right-click → Delete.

6. Driver conflicts: how to identify and resolve them

Incorrectly installed or outdated drivers (especially for video cards, network adapter or chipset) may block the reboot process. For example, driver NVIDIA sometimes it “forgets” to release video card resources, which is why the system waits for a response from the device.

How to diagnose:

• 🔧 Open Device Manager (Win + X → Device Manager).
• 🚨 Check for devices with a yellow exclamation mark (driver conflict).
• 🔄 Right-click on the suspicious device → Update driver → Automatic search.

If automatic updating does not help:

1. 📥 Download the driver from the manufacturer’s official website (for example, for Intel Wi-Fi adapter — with downloadcenter.intel.com).
2. 🗑️ Remove the old driver via Control Panel → Programs and Features.
3. 🔄 Install the new driver and restart the laptop.

To diagnose freezes on reboot, you can use Windows Event Log:

1. 📜 Click Win + R, enter eventvwr.msc.
2. 🔍 Go to Windows Logs → System.
3. 🔎 Filter events with code 6005 (system startup) and 6006 (correct completion). If there is a large gap between them, look for errors in the code 7000 or 7026 (problems with services).

7. Hardware problems: when is it time to take your laptop to a service center?

If all software methods have been tried, but the laptop still takes a long time to reboot, the reason may lie in hardware faults:

• 💾 Failed hard drive: if HDD begins to “crumble”, the read/write time increases tens of times. Check disk health in the program CrystalDiskInfo - if the status Pre-failure or Bad, urgently copy the data.
• 🔋 Worn out battery: If the laptop is running without a power connection, a weak battery can cause voltage sags, which slows down the reboot process.
• 🔥 Overheating: If the cooling system is clogged with dust, the processor throttles (reduces frequency), which slows down all operations, including reboots. Check the temperature in HWMonitor - if higher 90°C, cleaning required.
• 🖥️ Faulty RAM: errors RAM may cause freezes. You can check the memory using the utility memtest86 (runs from a flash drive).

If you suspect a hardware problem but are unsure of the diagnosis, run performance test:

1. 📊 Open Task Manager → tab Performance.
2. 📈 View the download CPU, RAM And Disk during reboot (if the system allows).
3. 🔍 If any component is loaded at 100% for longer than 2-3 minutes, this is a sign of a malfunction.

⚠️ Attention: If the laptop doesn't reboot at all (freezes at one stage for more than 20 minutes), do not forcefully turn it off - this may damage system files. Instead, hold the power button for 10-15 seconds for an emergency shutdown.

FAQ: Frequently asked questions about Windows slow reboot

❓ Why does the laptop turn on quickly, but takes a long time to reboot?

This is due to hybrid shutdown mode, which is enabled by default in Windows. When shutting down, the system saves the kernel to a hibernation file (hiberfil.sys), so switching on occurs quickly. But when rebooting, this file is not used, and the system boots from scratch, which takes more time. Disable Fast Startup in Power Options (see section 4).

❓ Can an antivirus slow down a reboot?

Yes, especially if it's Kaspersky, Avast or ESET NOD32. Antiviruses scan system files upon reboot, which can increase the time by 1-3 minutes. Try temporarily disabling real-time protection or adding a process winlogon.exe to exceptions.

❓ How to find out what exactly is slowing down the reboot?

Use Windows Event Log (eventvwr.msc):

1. Open Windows Logs → System.
2. Find the event code 6006 (correct shutdown).
3. See what errors or warnings were recorded before it (usually with codes 7000, 7026 or 10016).

You can also use the utility Process Explorer from Microsoft to monitor processes during reboots.

❓ Will switching from HDD to SSD help?

Yes, in 90% of cases. SSD speeds up reading system files by 5–10 times compared to HDD, so the reboot takes 10–20 seconds instead of 2–5 minutes. However, if the problem is driver conflicts or faulty RAM, replacing the disk will not help.

❓ Why did the reboot take longer after updating Windows?

Updates often make changes to register, services or drivers, which may conflict with the current configuration. For example, update Windows 11 22H2 added a new service Windows Update Medic, which checks the integrity of components on every reboot. Try rolling back the update or wait for the next patch from Microsoft.
