How to Fix Windows 8.1 Slow Performance and Boot Time

If you’re experiencing slow startup or boot time on your Windows 8.1, you’re not alone. Many users in the United States, Canada, the United Kingdom, Australia, and across Europe still run older laptops with Windows 8.1—and over time the system can become painfully slow.

The most common reasons for Windows 8.1’s slow performance include too many startup programs, fragmented hard drives, corrupted system files, outdated drivers, or malware running in the background.

Based on my experience fixing hundreds of slow computers, the operating system itself rarely causes the issue. Instead, it’s usually a combination of software clutter and aging hardware.

In this guide, I will show you step-by-step solutions to fix Windows 8.1’s slow boot, slow response, freezing issues, and internet speed problems. By the end of this tutorial, your computer should boot faster and run significantly smoother.

First of all, there are several scenarios!

• Is your boot time slow after shutdown?
• Or is it after a restart?
• Or is it slow after hibernation?
• Is it slow after sleep?

You can see my previous post on this subject for a tool to check boot times in Windows. This tool will help you visually, without any commands (a clean interface), to check how many seconds your computer takes to boot up in the different cases I listed above.

But first let me tell you my experience with this boot issue.

Why did I get irritated with Windows 8.1 64-bit at startup?

I don’t remember how exactly, but I was able to improve my boot speeds on my 32-bit Windows 8.1 OS. It was taking like 45 seconds to boot up. When I checked others on the BootRacer site, I found that some computers were even able to boot up in 7 to 8 seconds. Wow! That’s really fast…

I have a dual-boot configuration scenario. On one side is 32-bit Windows 8.1, and on the other is 64-bit Windows 8. My irritation started when the 64-bit was taking, like, 2 minutes or so to boot up. In addition to that, the computer started freezing after the boot-up was over. It would last for about 6-10 minutes. I don’t know exactly how to check that!

Why did I update from 8 to 8.1 on my 64-bit version?

One remedy I hypothesized was that the latest updates would likely decrease my boot times and solve my performance issues. Na, it was not the case-to-be. The problems persisted, and the same with the freezing issue, indicating that the updates did not address the underlying performance problems I was experiencing, which may be related to hardware limitations or software conflicts that were not resolved by the updates. So now I polished off the case that it was an update problem, just like doctors do.

I also updated the 64-bit system with the latest Update 1 release and several other updates.

Fix Windows 8 Slow Internet Speed

Users sometimes mistakenly attribute Windows 8.1’s slow performance to the system, when in fact, it’s due to internet latency.

Try:

• Reset network adapter
• Update WiFi driver
• Restart router

Check for Malware Causing Windows 8.1 Slow Response

Malware can run hidden background processes.

Run a full antivirus scan using:

• Windows Defender
• Malwarebytes

Remove suspicious programs.

Upgrade HDD to SSD for Faster Windows 8.1 Boot

The biggest performance improvement comes from replacing HDD with SSD.

Typical results:

Storage	Boot Time
HDD	60-120 seconds
SSD	10-20 seconds

An SSD upgrade can make Windows 8.1 feel like a new computer.

Advanced Troubleshooting for Windows 8.1 Slow and Freezing

Try these additional fixes:

• Disable visual effects
• Update drivers
• Increase virtual memory
• Perform clean boot

What to do initially when Windows 8 or 8.1 boot times are slow?

The first thing many Windows 7, Vista, and XP users know is to switch off some start-up applications and tablet apps. It applies to Windows ‘Metro‘ also. Refer to the “Task Manager” article for instructions on how to do this in Windows 8 or 8.1. A slight change is there on how to go to “msconfig” or disable start-up items, which now requires accessing the Settings app and navigating to the appropriate section instead of using the traditional method in earlier versions of Windows.

The second step is to disable services that are hogging your resources. 64-bit OSs have many services whose startup type is “Automatic” or “Automatic (Delayed Start).” “Some of them can be safely turned to “Manual” or “Disabled.”

But which one to and which one not to? You can follow this tutorial on your 8.1 computer. For 8 32-bit and 64-bit service configurations, you check Google with this query: “startup services to disable in Windows 8.” The search provides a helpful list of websites, which I checked. Otherwise, you can check the above site to find further information.

Another important step that you have not done is to check your computer for viruses, malware, adware, Trojans, and rootkits. This guide is a helpful article from Microsoft in such scenarios. Many of the forums suggest you submit your antivirus trace logs using different programs, which may be beneficial in the rarest of cases. Most of the current antivirus, Internet security, and cloud-protection software products are able to nullify, or eliminate, most of your problems if you are infected with malware.

One ambiguous step I don’t recommend is turning off “Pagefile” and disabling the “Superfetch” and “Windows Search” services. I found some resources to utilize this tip to improve boot speeds and computer performance. But there are pros and cons to using this step. I found some improvement in boot times when I applied the above step. That’s why I call the result a confusing footprint in your troubleshooting heuristics.

But it was inconsistent, and I also need to search for faster execution of my computer commands, which may involve exploring additional optimization techniques or software solutions to enhance overall system performance, such as adjusting system settings, upgrading hardware components, or utilizing performance-enhancing software.

What’s the Best Solution to Solve Your Windows 8 or 8.1 32-Bit or 64-Bit Boot Problems?

Hmm. You are waiting for an answer. If this problem truly bothers you, you’ll be waiting. Otherwise you might have left this post by now. It’s called “Windows 8 Performance Toolkit.” Yes, the process will be a little tricky! Why? Downloading this tool requires a reliable internet connection and sufficient bandwidth, as well as significant time to generate logs and analytical skills to interpret the reports.

I’m not a technical geek or expert in this scenario. All that I find is based on my own experience and some research on Google, which may not always provide comprehensive or accurate information about the tool’s functionalities and best practices, especially for someone like me who is not a technical expert and may struggle to understand the more complex aspects of the tool, such as how to effectively analyze performance data or troubleshoot issues that arise during its use.

This tool was also called “Xperf” in earlier versions of Windows. Now it’s known by the shorter names—WPT (Windows Performance Toolkit), WPR (Windows Performance Recorder), and WPA (Windows Performance Analyzer). It’s part of a bigger package called “Windows Assessment and Deployment Kit” (ADK).

To my knowledge, you must download ADK to get the WPT tool, so someone can comment on this post for a better link. You can choose to download several other tools or only WPT.

The download size was around 3.2 GB (WPT only) (don’t be fooled by the setup file size, which is only 1.2 MB), and the size is bigger if you want to download other tools. The download took a long time on my 2 Mbps connection, unlike other downloads, because I used Microsoft’s download tool. I did observe similar behavior with some of the official Microsoft downloads, where the download size was unexpectedly large and the download speed was significantly slower than anticipated.

You can use this tutorial on how to install this tool. As a guide to analyze your reports using WPT, these case studies would be useful.

My Experience in solving Windows 8 or 8.1 Boot Problems

From the case studies I have studied above, I observed that platter drives (old HDD hard disks) are the cause of boot issues in Windows 8 and 8.1 64-bit OS. See this comment on one of the above posts, which will make you agree to what I say.

Don’t come to a conclusion. This could be the sole reason for the issue.

As stated above, if you replaced your old HDD with an SSD (solid state drive) and are still experiencing problems, it can be related to drivers and updates. Always it’s best to check the compatibility of your driver for Windows 8 and 8.1. Also, sometimes updates can cause problems after installation, leading to issues such as system instability or failure to boot properly.

So was I able to solve the boot issue?

A sort of… Why? My current Windows 8.1 64-bit system takes approximately 120 seconds to boot. That is the same as I mentioned earlier. I was unable to implement my proposed solution to upgrade to a solid-state drive (SSD) due to a lack of funds, which could significantly reduce boot times. Unless I obtain a solid-state drive (SSD) and test the boot times, I cannot confidently say that the boot times are the problem.

What was the alternative?

The best thing I observed was that my boot times after shutdown and hibernate are not really affected by my existing 80 GB HDD (hard disk drive) on which my Windows 8.1 64-bit OS (operating system) resides. I was quickly able to come to the desktop screen after hibernate and shutdown (around 40 secs). The problem is only with restarting. So, as an alternative, I decided to restart less frequently.

What else did I do?

Also, I uninstalled the default Metro apps, which were not working, and reinstalled them. I also disabled and enabled the “Turn on fast startup (recommended)” at boot times to see if there was any change.

I also analyzed the reports from the WPR tool. The log was about 3 GB, and WPA (Windows Performance Analyzer) was used to view it.

The Windows Performance Recorder (WPR) will ask you for some options to check before you record the logs. Once given, it will restart three times, each time recording the boot scenario. Those logs are stored as files with the .etl extension. There will be 3 files. Double-clicking the file will automatically open Windows Performance Analyzer (WPA).

The above screenshot is one of the logs opened. As you can see above, the Storage tab shows that it’s full of disk activity during boot-up. If you click the arrow next to it, you’ll see some more options that allow you to analyze the disk activity in greater detail. Under File I/O, I checked the Size by Process, Duration by Process, and Count by Process windows.

You just have to drag and drop that window from the left onto the right side for a detailed view.

As you can see, the “System“ process is taking considerable hard-disk resources and time during the start-up. You can examine these logs in more detail for additional research if you are an administrator or expert.

Note: Some important confidential data about your computer may be present in these logs, so don’t share them with third parties.

I found that my memory and CPU were ok during boot-up using these reports.

Summary

It almost took 3 days to conclude conscientiously and agree that there is some other problem “alien” to my current expertise. So I decided to stop researching this topic and start working on my other jobs.

If your Windows 8.1 slow startup or performance issues are frustrating you, the fixes in this guide should dramatically improve your system speed. Simple troubleshooting steps can resolve most problems, including startup apps, fragmented hard drives, or corrupted files.

For the biggest improvement, consider upgrading your computer to an SSD (solid-state drive) and keeping startup programs minimal.
