Effective Solutions to Lenovo Laptop Running Slow Windows 11/10 

Before you take actions, you can make some quick fixes:

• Make sure that you've tried to restart the laptop several times if the 'slow boot time' happened for the first time.
• Make sure you have all the latest Windows updates installed on the laptop. If you are on the Internet when your Lenovo laptop is slow, make sure all browser plugins are up-to-date.

If these brief fixes don't work, try the following advanced workarounds one by one to solve the Lenovo laptop running slow problem beautifully.

Method 1. Clean Out the Dust

Your Lenovo laptop running slow Windows 10 may result from heavy dust in fan and heat sink. Tiny dust has a small impact on computer performance. Still, if your laptop collects a lot of dust, it will affect the computer's ability to cool itself, which may affect system performance and running speed.

In this case, you use a screwdriver or something like that to open your laptop correctly, then use a vacuum cleaner or a can of compressed air to blow the dust off the vents.​

Method 2. Check Memory and Memory Usage

Press Ctrl + Alt + Delete and then select Task Manager. In Task Manager, select the "Performance" tab > "Memory".

First, see how much you have total, and then check the graph and see how much RAM is being used.

Here's some info about the minimum memory requirements for Windows 10:

• Windows 10 (32-bit) can run on a PC with 1 GB of RAM, but it runs better with 2 GB. For better performance, add memory, so you have 3 GB or more.
• Windows 10 (64-bit) can run on a PC with 2 GB of RAM, but it runs better with 4 GB. For better performance, add memory, so you have 6 GB or more.

You can open Resource Monitor to end some process to free up some memory space. Right-click the process and click end process.

Method 3. Free Up Space and Increase C Drive to Speed Up Lenovo Laptop

If the hard drive or the system drive of your Lenovo laptop is nearly full, it will definitely lag. You can check for low disk space on your computer and improve performance by freeing disk space or increasing the C drive. 

How to check for low disk space and clean up the disk drive 

To check for low disk space:

• Select the Start button, and then select "Settings"  > "System"  > "Storage".
• Under Storage, your drives will be listed. Note the amount of free space and total size for each drive.

If there are a few or even no free space on your hard drive caused by tons of useless junk files, temporary files (Automatically delete Temp files), large files, or dozens of third-party applications, how to clean them up? Well, it's natural for you to start manually checking the files and programs stored on the PC. But, that can be way too time intensive.

EaseUS Partition Master, the partition software, comes with quicker and easier ways to solve the Lenovo laptop running slow problem effectively.

How to increase C drive to speed up Lenovo laptop windows 11/10

What's more, an advanced disk/partition conversion function is also available for you to convert FAT to NTFS, MBR disk to GPT, or GPT disk to MBR. Now, let's see how to use this tool to increase the C drive on your Lenovo laptop to improve performance.

Option 1. Extend System C drive with unallocated space

1. 1. Right-click on the System C: drive and select "Resize/Move".
2. 2. Drag the system partition end into the unallocated space so to add it to the C: drive. And click "OK".

If you're tired of waiting too long to boot up Windows OS on your HP PCs, why not invest in an SSD? Use the best hard drive duplicator software to upgrade HDD to SSD without reinstalling Windows.

Method 4. Disable Unnecessary Startup Programs

When you turn on your PC, some programs start automatically and run in the background. You can disable these programs, so they don't run when your PC starts.

Many programs are designed to start automatically when Windows does. Software manufacturers often set their programs to open in the background - you don't realize they're running, but they'll open quickly when you go to use them. This is helpful for programs you use a lot, but not for programs you don't often use because it increases the time it takes Windows to start.

• Select the Start button, and then select "Settings" > "Apps" > "Startup".
• Under Startup Apps, find the program you want to stop from starting automatically and set it to Off. 

Method 5. Make Sure Your Lenovo Is Free of Malware

A virus, malware, or malicious software could cause your Lenovo laptop to slow. The best way to handle viruses and malicious software is to try to prevent them by running antimalware and antivirus software and keeping it up to date.

You can scan your PC for viruses or other malicious software by using Windows Security (formerly Windows Defender Security Center), which is included in Windows 10. Or you can apply other well-known antivirus software, such as Avast, AVG, Avira, Kaspersky, etc.

Method 6. Upgrade Hardware

The most effective way to solve this problem is by upgrading hardware for a real performance boost.

Upgrade RAM

If your Lenovo laptop runs very slowly when you are doing design work, such as photo editing, video making, 3D modeling, or other similar things with large software, consider adding more RAM (random-access memory). RAM upgrades can speed up Lenovo laptop, and you'll experience fewer system freezes or hangs.

Upgrade to SSD

An SSD has access speeds of 35 to 100 microseconds, which is nearly 100 times faster than a traditional HDD. Replacing your Lenovo's spinning hard drive with a new SSD is almost a solution that promises to improve your Lenovo performance and fix the running slow issue. How to migrate OS from HDD to SSD? Use EaseUS Partition Master Professional again and follow the step-by-step guides below to upgrade your Lenovo to SSD. 

Steps to migrate OS to HDD/SSD:

• Run EaseUS Partition Master, and select "Clone" from the left menu.
• Check "Migrate OS" and click "Next".
• Select the SSD or HDD as the destination disk and click "Next".
• Check Warning: the data and partitions on the target disk will be deleted. Make sure that you've backed up important data in advance. If not, do it now.
• Then click "Yes".
• Preview the layout of your target disk. Then click "Start" to start migrating your OS to a new disk.

• After this, click "Reboot Now" or "Done" to determine if you want to reboot the computer from the new disk immediately.

"Reboot Now" means to keep the changes instantly, while "Done" means you need to restart the computer later manually.

Note: The operation of migrating OS to SSD or HDD will delete and remove existing partitions and data on your target disk when there is not enough unallocated space on the target disk. If you saved important data there, back up them to an external hard drive in advance.

Method 7. Disable Windows 11/10 Automatic Update

Don't ignore one truth. Each Windows 10 update causes problems. Even you've tried all the recommended solutions above; it's still necessary to consider a permanent close for Windows 10 automatic update.

It is indeed very annoying to be faced with the automatic Windows 10 Update. Disable the automatic update in every way now.
