Usually, no: deleting Windows thumbnail files is not an established general-purpose speed boost. Microsoft lists thumbnails as files Disk Cleanup can remove to free disk space, not as a performance fix. It may help indirectly if your system drive is nearly full and the extra space matters to your PC.
What clearing the thumbnail cache does
Windows stores thumbnails it has generated so image and video previews can appear in folders. Disk Cleanup can delete those files. As you browse folders again, Windows may generate thumbnails anew.
Microsoft’s Disk Cleanup guidance for Windows 10 and Windows 11 describes removing thumbnails as a way to free drive space. It does not report a thumbnail-cache-specific speed test, typical cache size, or expected performance gain. The space recovered and any effect on speed therefore depend on the individual PC; no fixed figure or measurable improvement can be promised.
When deleting thumbnails may be useful
If the system drive is running low on space, clearing thumbnails can contribute a little usable space. Microsoft notes that low disk space can affect performance, so freeing space may help in that circumstance—but only insofar as the deletion frees useful space. It is not a substitute for addressing a more significant storage shortage or another cause of slowness.

It is also a reasonable occasional cleanup or troubleshooting step. It is not necessary as routine performance maintenance, and Windows may rebuild the thumbnails as needed.
How to clear thumbnails with Disk Cleanup
- Search Windows for Disk Cleanup and open it.
- Select the drive you want to clean, usually the system drive, and continue.
- In the file categories, select Thumbnails if you want to delete them. Microsoft notes that this category may already be selected by default; clear its checkbox if you want to keep the thumbnails.

Other checks if Windows is slow
If the PC remains slow, consider the symptom rather than repeatedly deleting thumbnails. Microsoft recommends checking several possible causes and remedies:
- Low free space: Review storage and use Disk Cleanup or Storage Sense to remove items you no longer need. Storage Sense is an automatic space-cleanup option, not a thumbnail-cache speed fix.
- Slow startup: Review apps that launch when you sign in and disable ones you do not need.
- High resource use: Use Task Manager to see whether an app or background activity is consuming substantial resources.
- Updates or malware: Check Windows and driver updates, and scan for malware.
- Power or drive concerns: Check the selected power mode and whether drive optimization is appropriate.
Microsoft cautions that software cleanup may not produce significant gains on older hardware. Its broader guidance is in Tips to improve PC performance in Windows. For Storage Sense, see Manage drive space with Storage Sense.
