Enable/Disable Thumbnail Caching

One of Explorer's great features is to display a thumbnail of images and

the first frame of the video when seen in Thumbnail view. This is either done when you access the folder or it fetches from the thumbnail cache. Fetching thumbnails from the cache is  lot faster, but will consume a lot of hard disk space, especially if your system is full of images and video.Thankfully you can disable this. or in case you have sufficient space but want to speedup your system then you can enable it in case disabled.

Navigate to:

HCU\Software\Microsoft\Windows\CurrentVersion  \Explorer\Advanced

Set the DWORD Value DisableThumbnailCache to 1 if you are low on hard disk space. Otherwise chang/leave it at 0 to enable thumbnail caching
