Steps to Enable TRIM in Windows 7 and Above for SSD


Generally, TRIM support is meant for Solid State Drive (SSD) installed on your Windows Operating System. Many people prefer SSD in comparison to Hard Disk Drives (HDD) due to the manner in which they store information. Once you install a new SSD on your Windows platform (Windows 7 and above) and boot for the first time, you need to check if this TRIM feature is enabled or not. As a norm, it should be enabled by default. However, due to some issues or accidental changes, the TRIM support may have been disabled on your Windows platform. In such cases, you need to find a way to enable TRIM on your Windows 7 (or higher) SSD.

In this article, we shall understand the advantages of TRIM support, tips to check whether TRIM is activated or deactivated on your Windows OS and how to manually enable TRIM on SSD.

Why is TRIM support required for Windows OS?

When a new SSD is installed, the TRIM feature empties some space on it that was previously used by a deleted file. Thus, it allows Windows to reuse memory locations (that are no longer required) straight away instead of spending time in searching for the unused locations on the drive. Thus, we can say that activated TRIM support protects your SSD from slowing down after continuous usage. In other words, it helps increasing the longevity of Solid State Drive for your Windows platform and ensures its smooth functioning. So, TRIM is absolutely necessary to maintain the performance of SSD.


How to check if TRIM is enabled or disabled?

Open the search box from Start.

Start in Windows 8

For Windows 7, the search option is easy to find once you click on Start. For Windows 8 and above, you will have to go Start section and type ‘S’ for the search box to appear.

If the result seen is DisableDeleteNotify = 0, it means TRIM feature is enabled. Otherwise, if DisableDeleteNotify = 1, then, TRIM is disabled for your SSD.

How to enable TRIM if it has been disabled due to some reasons?

You have to open the DOS command prompt window by following the same steps as mentioned above. Type fsutil behavior query DisableDeleteNotify 0 in the command prompt window and press “Enter” from your keyboard. This simple step will turn on TRIM support.

Enable TRIM

Thus, by typing some standard text in the command prompt window of your OS, you can keep a track of the TRIM status as well as change it as per your requirement for smooth working of your SSD. Hope this information (about how to enable TRIM in Windows OS) will help you to make optimum use of this feature for Windows 7 or higher.
