How to fix
Windows very slow after formatting
on Windows

Hi, I have recently formatted Windows because I couldn't get it to work properly. Unfortunately, after doing so, I am now faced with what si a very slow Windows PC. I have no idea why this is happening and would like to get some advice.

Formatting a computer essentially means erasing all the data on the hard drive and preparing it for a fresh installation of an operating system (OS) such as Windows. Individuals often resort to formatting when their computer starts malfunctioning or when it becomes bogged down with too much unnecessary data, which can cause performance issues. By formatting, you are essentially providing the computer with a clean slate, devoid of any software, files, or lingering problems that might have hampered its functionality.

After the format, a fresh installation of the OS is needed. This usually involves using a Windows installation disk or booting from a USB drive. The OS then sets itself up on the now-empty hard drive, offering a pristine version of Windows, unburdened by old data or settings.

However, some individuals encounter an unanticipated predicament after formatting. Instead of being greeted by a revitalized, efficient system, they notice that Windows becomes very slow after formatting.

One might wonder why this slowdown happens. One reason could be an incomplete installation. If the OS installation process gets interrupted or fails to complete correctly, it might leave behind fragmented files or configurations that can hamper performance.

Additionally, a newly installed Windows might not come equipped with the latest drivers for specific hardware components. Without these drivers, parts like the graphics card or sound system might not operate at their optimum, leading to diminished system speed.

Moreover, a fresh installation might have default settings that allow for numerous programs or processes to run in the background. These can consume a significant portion of system resources and lead to a slowdown. Another possibility is that the version of Windows you've installed isn't the latest one.

Consequently, it would lack recent patches or performance enhancements. Lastly, there's always the chance that the problem doesn't lie with the software but the hardware itself. Aging or malfunctioning hard drives can be culprits behind performance issues, even after a fresh OS installation.

If you're grappling with a sluggish performance after a format, it's essential to pinpoint the exact cause. This understanding can guide your corrective actions, whether it's downloading the latest drivers, tweaking certain settings, or ensuring the most recent Windows updates are in place.

For those on the lookout for an efficient, automated solution to various Windows issues, the [d1] PC repair tool stands out as a commendable option.

Fix 1. Run Check Disk in Command Prompt

Check Disk or chkdsk, is a built-in Windows utility that checks for and repairs file system errors and bad sectors on your hard drive, which can sometimes cause a computer to slow down.

• Open the Start menu and type cmd.
• Right-click on Command Prompt and select Run as administrator.
• When UAC shows up, click Yes.
• In the new window, type in the following command and press Enter after:
  chkdsk c: /f
  (Note: use chkdsk c: /f /r /x command if you are using SSD as your primary partition)
• If you receive an error, type in Y, close down Command Prompt and restart your system.
• Wait until the scan is finished - you can find the results in the Event Viewer.

Fix 2. Restart Sysmain service

Sysmain, formerly known as Superfetch, aims to enhance your system's performance by managing the kind of data stored in your memory. Sometimes, restarting this service can help with system performance.

• In Windows search, type Services, and press Enter.

• Once you've located Sysmain, right-click on it. From the dropdown menu, select the Restart option. If Restart isn't an option, you can select Start instead.
• After a moment, the service will restart.

Fix 3. Update drivers

Drivers are software components that let your operating system communicate effectively with hardware components. Outdated drivers might lead to slower performance.

• Right-click on Start and pick Device Manager.
• Within Device Manager, you'll see a list of hardware categories. Expand these categories to check for any devices that have a yellow triangle icon next to them. This indicates a potential driver issue.
• For each device with a yellow triangle, right-click on it and choose the Update driver option. Follow any on-screen instructions.
• Alternatively, to bypass various driver problems, try using an automatic solution such as [rev id="DriverFix"].

Fix 4. Install Windows updates

Keeping Windows updated ensures your system has the latest security patches and performance enhancements.

• Type Updates in Windows search and press Enter.
• Here, click Check for updates.
• Wait till Windows downloads and installs all the files.
• If optional updates are available, install them as well.
• Reboot your computer.

Fix 5. Disable unnecessary startup programs

• To access the list of startup programs, press Ctrl, Shift, and Esc simultaneously. This will open the Task Manager.
• Navigate to the Startup tab.
• You'll see a list of programs with their startup impact. Right-click on those you feel are not essential and select the Disable option.

Fix 6. Optimize hard drive performance [HDD only]

Fragmented files can slow down data access on your hard drive. Defragmenting reorganizes these files for faster access. Please keep in mind this solution is only applicable to those with Hard Drives (HDD) and should not be performed on a Solid State Drive {SSD)

• Press the Windows key to open the Start menu.
• Type defragment into the search bar and press Enter.
• A window titled "Optimize Drives" will appear. Here, select your primary drive (usually labeled as C:).

• Under the Performance section, click Settings.
• In the new window, you'll see a list of visual effects. For better performance, choose the option Adjust for best performance and click OK.

Fix 8. Set power plan to High Performance

Windows provides different power plans that balance performance and energy usage. Setting it to High Performance can sometimes boost system speed.

• Type Control Panel in Windows search and hit Enter.
• Here, go to Hardware and Sound > Power options.
• Here, you will see the listed plans.
• Change the plan from Power saver to High performance.

Fix 9. Perform a Clean Boot

A clean boot starts Windows with the least number of drivers and startup programs. This can help identify if third-party applications are causing performance issues.

• Press the Win + R to open the Run dialog.
• Type msconfig and press Enter.
• In the System Configuration window, select Selective Startup, and uncheck Load startup items.
• Go to the Services tab and check the box Hide all Microsoft services, then click Disable all.
