For a while now I have been annoyed by the size of Windows XP’s thumbnail preview size. It was just too small. It would make searching for specific photos much quicker if it was larger. After some searching on Google, I found a few websites that listed an easy way to modify the size and quality of those thumbnails and I would like to share this information with you as it may be helpful!
Before proceeding, you agree that you accept all liability of anything you do or have read results in your computer misbehaving or not functioning as it should. It should also be noted that you need to know how to navigate and edit the registry.
Using Regedit you need to navigate to;
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
Once there right click and create a new DWORD entry. Set the properties as they are shown below.
- ThumbnailSize Hex 100
- ThumbnailQuality Hex 100
If you have done everything correctly, then your regedit window will look like mine!
Your changes should be immediate. All you need to do is close any open windows that have thumbnails and re-open them!
