How to Speed up Thumbnail Loading in Windows 10

Speed Haven’t we sat down to show all your recent vacation pictures to friends? However, the enthusiasm dies away because the thumbnails take ages to load on your Windows PC. That can turn out to be quite an exasperating affair, especially if you have to locate a few important photos quickly.

That issue is more rampant in systems carrying plenty of media files inside folders. In a normal scenario, Windows 10 keeps a cache of the thumbnail files for your files and folders. So, when you open a folder, the contents are ready for you to view.Speed

With time, this cache slowly starts bloating as new files are added to the system. And that is one of the reasons that Windows File Explorer takes its own sweet time to display the thumbnails. Or, in the worst-case scenario, your system shows the incorrect previews of the files.

Thankfully, the changes are not permanent, and with the right solution, one can rectify this issue quickly. In this post, we will explore four different ways to speed up the thumbnail loading time in Windows 10.

If you are lucky, you’d need to do only one of the fixes for the issue to be rectified, while in others, you may need to try all the three.

1. THROUGH GROUP POLICY

Step 1: Open Group Policy by typing Edit Group Policy (or gpedit.msc) in the Start menu. As you may already know, Windows Group Policy has a set of advanced local settings that you can tweak, provided you know your way around them.

Step 2: Once inside, navigate to User Configuration > Windows Components > File Explorer.

Step 3: Now, search for the ‘Turn off the caching of thumbnails…’ option. The chances are that this option will be either in the Not Configured state or disabled.

All you have to do is select Enabled and hit the Apply button.

Once you have applied the above, reboot your computer for the above changes to take effect.

2. THROUGH THE CONTROL PANEL SETTINGS

Next, we have to make sure that your system is posed to show all the thumbnails of files and folders. To do so, follow the steps below.

Step 1: Open the Control Panel of your system and head over to System and Security > System, and click on the Advanced system settings.

Step 2: Select the Advanced tab and select Settings under Performance.

Here, you just have to make sure that the ‘Show thumbnails instead of icons’ option is enabled. If it’s not, check the box and hit OK.

3. CHECK THE REGISTRY VALUES

Last but not least, you may want to edit the Registry values. Quite obviously, your system has a ton of maintenance tools that runs automatically. And as you may have suspected, one of its jobs is to clean up the File Explorer’s cache regularly.

Just like your browser and your phone, clearing up the cache makes new space, which is good from the storage point of view. But at the same time, the File Explorer also has to reload the cache, which ends up consuming time.

Hence, if you’re really frustrated with the slow load time, you may want to tweak the values a little so that the Disk Cleanup job is not triggered for the thumbnail cache. Usually, the Disk Cleanup job (going by the name of SilentCleanup) picks up the autorun job with values 1. Naturally, if you change it to 0, it’ll cause the job to skip these keys.

To do so, open the Registry Editor by typing Regedit on the start menu.

Next, navigate your way around to the following path,

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches

Here you’ll see two values, Default and Autorun. All you have to do is set the Autorun’s DWORD value to 0.

Do so for the following path as well,

HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Thumbnail Cache

Once done, reboot the PC to make the changes take effect.

4. CHANGE THE THUMBNAIL CACHE SIZE

You may also want to increase the cache size if you do have the habit of keeping all your pictures and images under a single folder. And as you might have guessed, the way is through the registry values.

Open the Registry, and navigate to the path below,

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explore

Once done, right click on an empty space and select New. Next, select New > String value and add the term, Max Cached Icons.

Now add the value 4096 and hit the OK button. This tweak will create a 4MB cache file.

If you want a slightly bigger cache file, you can update this update the value to 8192 as well. By default, the icon cache size in Windows is around 500KB.
