Tweaks To Fix Windows 10 Very Slow & Unresponsive Issue


#Fix 1 – Scan for Virus/Malware

Just like the predecessor Windows 10 is also vulnerable to virus and malware infection. And if the PC/laptop is infected with viruses, then this can make your computer run slow.

So, make sure to scan your Windows 10 system with good antivirus software at a regular interval of time. If you are searching for a reliable antivirus tool, then here I strongly recommend you using Spyhunter.

It has multiple advanced features that will help you to keep your PC safe from virus/malware threats and will also remove the malware/virus o=infection from your computer.

Or you can also try removing the virus without using the antivirus software. For this, you need to do the following:

  • Type cmd in the Windows Search bar.
  • Right-click on the Command Prompt and select Run as administrator.

#Fix 3 – Enable Fast Startup Option

Microsoft has added the latest feature named Hybrid Startup and Shutdown. This will put your PC/laptop into the hibernation state and improves the startup and shutdown process.

This may consume somewhat more power but don’t turn off the machine completely. So, make sure to enable the fast startup option. Follow these steps to do the following:

#Fix 6 – Defragment your drive

As said above, the corrupted or fragmented hard drive can cause the Windows 10 slow to respond. So, here you need to defragment your drive, but if you are using the solid-state drive then skip this solution.

Windows 10 is having its own fragmentation tool, you can defragment your drives by using this. For this you need to follow the given instructions:

  • Press the Windows + S key and type defrag on the Windows Search box.

#Fix 7 – Update your Drivers and Software

The outdated drivers and applications can also make the windows 10 slow, lagging, and freezing and the running programs get stuck in between. So, it is very important to update them with the latest updates.

Just like the applications, it is also important to update the outdated drivers as this may cause Windows 10 to slow to perform.

To update the drivers you can go to the Microsoft official website or to Manufacturer’s official website and search for the latest update and install them.

Despite this you can also make the whole process easy by making use of the Driver Easy, this automatically updates the drivers and fix other drivers related issues.

#Fix 8 – Adjust the Size of Virtual Memory

Virtual memory is very important for Windows 10 to perform better. Windows 10 automatically manages the size of virtual memory but it can be changed manually as well. Follow the steps to do so:

  • Press Windows + S key and type advanced.
  • Choose View advanced system settings from the search result.

  • Now System Properties window appears. Click on the Settings button in the Performance section.

  • In the Performance Options window, go to the Advanced tab and click on the Change button.

  • As the Virtual Memory window opens, uncheck the automatically manage paging file size for all drives checkbox.
  • Choose the Custom size, and enter Initial Size and Maximum size.

  • Then click on the Set and OK button to save the changes you have made.

And after this, you need to set the virtual memory size for that drive and to fix the Windows 10 PC is very slow and unresponsive issue, you have to set the manual size for all drives.

The size of the virtual memory is related to the size of the RAM and as a common rule, the initial size should be at least 1.5 times larger than the amount of RAM memory on the PC.

And for maximum size, it should be at least 4 times larger than the amount of RAM on your PC.

#Fix 9 – Run SFC and DISM

Corrupted Windows system files often lead to various errors and issues on the computer. And these issues directly impact the performance of the PC.

So, if your Windows 10 PC is running slow and becoming unresponsive, then you can try the Windows inbuilt tool to deal with this issue. Here you have two tools SFC and DISM.

First, we will run the SFC tool and if it failed to fix the Windows 10 performance issue, then we will go with the DISM. So, to run the SFC scan, follow these steps:

  • For this, first, open the Command Prompt as admin.
  • In the Command Prompt, execute this command, and don’t forget to press the Enter key:
