Tool 2. Free disk speed test app

The Windows built-in tool doesn’t check detailed disk performance, so if you wish to carefully check the reading and writing speed of your disks, you can choose AOMEI Partition Assistant Standard, a free disk and partition manager for Windows 11/10/8/8.1/7/XP systems.

The “Disk Speed Test” provides simple test and Pro test modes to help users test disk speed for different requirements. And after the test, you can export the test result to read all details.

How to improve PC performance and speed it up?

After you check the computer performance and disk speed, you may have found the problem that makes the performance of the PC decrease. In this part, we list some practical methods to help you improve PC performance.

Method 1. Check the Windows updates and device drivers

Check that you have the most recent version of Windows installed. When you check for updates, your PC will also look for the most recent device drivers, which can assist improve the performance of your computer.

Step 1. Select the Start button, then select Settings > Windows Update > Check for updates.

Step 2. If the status says "You're up to date," continue and check for optional updates. If the status says "Updates are available," once they are downloaded, select Install now.

Step 3. Select the updates you want to install, then select Install, restart your PC, and see if it seems to run better.

Method 2. Ban some apps in the Startup settings

You can restrict the number of programs that execute during startup.

Step 1. Open Settings > Apps > Startup.

Step 2. Click the Sort by menu and select the Startup impact option.

Step 3. Turn off the toggle switch for any unnecessary app especially those marked as "High impact" by the system.

Disable the startup apps

Method 3. Uninstall some useless apps

Your computer comes pre-installed with a slew of software that the majority of users will never use, but which may eat up a lot of system resources and disk space. These are often detected by a pop-up prompting you to upgrade a previously unknown application.

Step 1. Click on the "Start" button and visit the “All apps” menu

Step 2. You can view a list of the applications you have installed and those you haven’t. Once you find the program you want to uninstall, right-click on the icon to see the "Options" menu.


Method 4. Use third-party App Mover to relocate apps

If you do not want to delete any software, you may upgrade the Standard Edition of AOMEI Partition to the Professional edition to relocate large programs to another drive/disk, freeing up space on your system drive.

The Pro edition has an "App Mover" function that allows you to transfer installed programs after scanning the disk to identify any moveable applications and folders. After the operation is complete, you can run your applications from the new storage path, and your data will be saved in the new place.

▶ Note: Make sure the target drive has sufficient free space to save all you move. If there’s a notice that tells you the space is insufficient, you can extend the partition at first.

Step 1. Run AOMEI Partition Assistant Professional, click “Free up” > “App Mover”.

App Mover

Step 2. In the new window, click “App Mover”. If you wish to move Users folders or Profiles folders, you can click “Move Folders”.

2 options

Step 3. In the pop-up window, choose the partition that you want to free up via moving apps (here is partition C) and click “Next”.

Select partition

Step 4. In the window, all movable apps on the C drive will be listed. You can choose one or multiple apps that you need to move and the destination partition. Then click “Move” to execute the operation.

Tick apps

Step 5. Confirm that you have closed the apps that you will move from C drive to D drive. Then, click "OK".


Step 6. Wait for the move process to complete. Then, click "Finish".

Method 5. Upgrade hard disk

If you’re using an HDD as the system disk for your PC, then we suggest you replace it with an SSD. SSD has better performance, faster data processing speed, and a more stable physical structure. And now, the SSD with the same capacity as an HDD is not as expensive as before. You can enjoy better disk performance on your PC with a suitable SSD.

To properly replace your disk, we recommend that you clone it instead of reinstalling the system and all of your programs. AOMEI Partition Assistant also has a "Drive Clone Wizard" capability that can clone a hard disk to another and offers two cloning methods. You may also resize and align the SSD partition throughout the operation.

After you back up all important data files and steadily connected your SSD to your computer, we can start.

Step 1. In the main interface of AOMEI Partition Assistant Professional, please click “Clone” and then “Clone Disk”.

Disk Clone Wizard

Step 2. Select a copying method you need from "Clone Disk Quickly" and "Sector-by-Sector Clone". Here, we select “Clone Disk Quickly” as an example.

Choose cloning method

▶ Notes:
☛ “Clone Disk Quickly” only copies the used sectors to the destination location, allowing users to clone the larger disk to a smaller disk.
☛ “Sector-by-Sector Clone” will copy all sectors to the target disk, so the destination disk must be equal to or larger than the source disk.

Step 3. Select the Windows system disk as the source disk and hit “Next”.

Source disk

Step 4. Then select the SSD drive as the destination disk and click “Next”.

Target disk

Step 5. Now, you can also resize partitions just being created on the SSD drive.


Step 6. Read the subsequent boot note, click “Finish” and then click “Apply” to execute the pending operation.


Tip: If you want to move OS only, you can choose the “Migrate OS to SSD” feature.

Method 6. Clean junk files

Junk files will affect hard disk performance. If you haven’t cleared junk files for a long time, then cleaning junk files may improve PC performance a little.

Step 1. Press Windows + S, search for Disk Cleanup, and double-click the search result to open this tool.

Step 2. In the pop-up window, select the drive you want to clean up from the drop-down menu and click OK.

Step 3. Wait patiently until the tool finishes scanning this drive. Then, in the new window, click Clean up system files to scan for more system cache.

Disk Cleanup

Click "Start" and "Settings" in turn, then click "System". In the new window, click "Storage" and turn on "Storage Sense".

Storage sense

If you want deep cleaning, you can use the “PC Cleaner” function of AOMEI Partition Assistant.

This post shows you how to check the performance of your PC and speed it up. To keep the performance of the PC at a nice level, you need to keep nice maintenance in daily use. AOMEI Partition Assistant is a practical partner to help you manage your disks. Besides the functions we’ve mentioned above, this tool can also convert disk to MBR/GPT without deleting partitions, convert file systems between NTFS and FAT32 without formatting, completely wipe and erase a hard disk, etc.

And if you need, you can choose the Server Edition which is specifically designed for Windows Server users (supporting Windows Server 2022/2019/2016/2012(R2)/2008(R2)/2003).
