About Windows Update Errors

Microsoft continuously optimizes its Windows operating system by rolling out updates, like the upcoming Windows 10 v1909 (November 2019 Update), recent Windows 10 v1903 (May 2019 Update), and earlier Windows 10 v1809 (October 2018 Update). Generally, these updates contain improvements to the existing features, services, or programs, the fixes for the known issues, and the release of new features, aiming to provide users with better system performance. However, Windows updates are always accompanied by various serious or minor problems. Some of the issues are exclusive to the current version, like:

But some others seem to be a universal problem caused by Windows update, including:

  • Updates may fail to install and you may receive Error 0x80073701
  • Windows crashes with a blue screen after update
  • Intermittent loss of Wi-Fi connectivity

And the one we will discuss in detail: Windows 10 slow to boot/startup after the update. Although issues with Windows updates are expected, these problems can be really annoying if they affect your work/study effectiveness. If you are preparing for an update, knowing some Windows update tips could be helpful. If you have updated Windows and encountered a problem like Windows 10 slow to boot after the update, read on to get the causes and solutions.

  • Malware or spyware
  • Windows startup programs
  • Fragmented files
  • Corrupted system files
  • Incompatibility between your current drivers and the Windows 10 update
  • Incorrect configuration in BIOS

...

Don't know the specific reasons that cause the Windows 10 slow boot issue on your computer? If so, follow the tips below in order. Before the start, make sure you have updated to the latest version of Windows. As mentioned, a Windows update always includes fixes for known issues. To check and install a new Windows update:

Step 1. Click "Start" and type update.

Step 2. Choose "Check for updates".

Step 3. Windows will show you the new updates available. Click "Install now" to update your Windows.

Update to the latest version of Windows

If there is no Windows update available or the update fails to fix the Windows 10 booting slow issue, don't worry. You have more workable ways to try.

Tip 1. Run Windows Defender (or Anti-Virus software) to Remove Virus/Malware

Viruses and malware attack your computer in various ways, e.g. deleting your files, encrypting your folders, and making your computer running slow. To scan for potential viruses or malware existing on your computer, you can either use Windows Defender or the anti-virus software you installed. To use Windows Defender:

Step 1. Go to "Settings" > "Update & Security" > "Windows Security".

Step 2. Click "Virus & threat protection".

Step 3. In the "Threat history" section, click "Scan now" to scan for viruses on your computer.

Step 4. If there are viruses or malware found, follow the onscreen instruction to remove them.

Tip 2. Disable Unnecessary Startup Programs

A startup program is a program or utility that is started automatically when the computer boots. Some programs are enabled as the startup programs during the installation, which you can hardly notice. It's not difficult to understand the logic that the more startup programs you have, the longer it will take to boot your computer. Therefore, to speed up the boot of your Windows 10 computer, you can disable some unnecessary startup programs.

Step 1. Right-click any space on your taskbar and choose "Task Manager".

Step 2. In the "Task Manager" window, go to the "Startup" tab.

Step 3. Select the programs you rarely use, or don't always need on startup, and click "Disable" to remove it from the startup programs.

Tip 3. Defragment Computer Hard Drive

Fragmentation is storing a file in noncontiguous areas on your disk and thus your storage space is used inefficiently and thus your hard drive performance is reduced. Succinctly speaking, defragmentation is the process of eliminating fragmentation on your hard drive, serving the purpose of improving the read and write speed of your files and thus speeding up your computer.

Step 1. Input defrag in the search bar.

Step 2. Choose "Defragment and Optimize Drives" in the search result.

Step 3. Choose the hard disk you want to optimize and click the "Optimize" button.

Tip 5. Update Graphics Driver

If your Windows 10 is slow to boot after an update, it may hint that there is an incompatibility between the latest Windows update and your computer drivers, especially the graphics driver. The latest driver may provide better compatibility with the new release of Windows 10. Therefore, it's also worth trying updating the graphics driver on your computer.

Step 1. Right-click on "This PC" and go to "Manage" > "Device Manager".

Step 2. Expand "Display adapters", right-click on the graphics card driver and choose "Update driver".

Tip 6. Change Boot Order in BIOS

If BIOS is not configured properly, it will affect your PC's startup process. Make sure your first boot device is system hard disk. 

Step 1. Start the computer and press ESC, F1, F2, F8 or F10 during the initial startup screen. Depending on the BIOS manufacturer, a menu may appear.

Step 2. Choose to enter the BIOS setup. The BIOS setup utility page appears.

Step 3. Use the arrow keys to select the "BOOT" tab. System devices appear in order of priority.

Step 4. To give the boot sequence priority for the drive which would speed up the Windows 10 boot time, move it to the first position in the list.

Step 5. Save and exit the BIOS setup utility. The computer will restart with the changed settings.

The six tips above are the corresponding fixes to the possible causes mentioned above. If your Windows still boots slowly, don't give up. There are more proven and tested ways for you to boost your computer performance.

Tip 7. Increase the Page File Size

The page file is a hidden system file located in your system drive. When your RAW is full, Windows will place some of the data from RAM to the page file on your hard drive. Thus, this virtual memory enables your computer to run more smoothly by easing the workload of the physical memory, RAM. By increasing the page file size, you can potentially optimize the startup time of your Windows 10 computer.

Step 1. Type advanced system in the search bar and click "View advanced system settings".

Step 2. Under Advanced, click "Settings" in the "Performance" section.

Step 3. Go to the "Advanced" tab and select "Change..."

Step 4. Uncheck "Automatically manage paging file size for all drives" and click "Custom size".

Step 5. Set the Initial size and Maximum size. (You can refer to the Microsoft guide on how to decide appropriate page file size.)

Step 6. Click "Set" > "OK" and then restart your computer.

Tip 8. Upgrade to SSD

If you are using a mechanical hard drive and want to improve the boot time of your computer, switching to an SSD is a good choice and the effect is immediate. Although with less capacity, SSDs have much better performance than HDDs. By upgrading to an SSD, the computer will take less time to boot up, the programs will take less time to load, and the files will take less time to open and save. If you attempt to try this tip, learn how to migrate OS to SSD without reinstallation will do great help.

Other Windows-Slow-to Issues

Other than Windows 10 slow to start up, there are more Windows-slow-to issues that are troubling many users. You can catch a glimpse of them:

The Bottom Line

I'm sure you can fix the Windows 10 slow to boot issue using one or more of the tips detailed. As more extra information on the fixes, I'd like to say that defragmentation should be done on a regular basis since fragmentation happens all the time. Most of the tips are easy to apply except for OS migration. Yet as long as you follow the related guide strictly, you will find it's simple, too.
