As we all know that we can optimize PC performance in many ways, but have you ever hear about a SHS file? Do you know what it is? And how does it affect the PC performance? If not, please do not miss this article. 

First of all, it is necessary for us to know what SHS file is. When using Microsoft Word and Microsoft Excel, it is possible for us to drag and drop selected items like document text, drawing objects, and graphics to the Windows desktop. At this time, there will be a desktop icon creating for the scrap file, along with a file located on the Windows\Desktop with a .shs extension. Hence, we can say that this file is a native program document which contains the information that was selected and dragged. 

With a SHS file, we can simply drag it to other documents which meet the shortage of the Windows Clipboard, only retaining the latest copied content. 

From the discussion above, it seems that the SHS file will bring us more convenience. But please note that the scrap file is a special OLE object and it is impossible for us to see the shs extension in Windows operating system (except in Dos and Linux). So lots of anti-virus experts warm us to keep strong vigilance when receiving some emails with hidden extensions like shs for they may contain some malicious codes which can destroy all of your data, for example, a virus attachment named with FAMILY_PHOTO.JPG.SHS, when coming to the receiver, what he/she see maybe only FAMILY_PHOTO.JPG. Most of the time, they may select to open the attachment without consideration for .JPG is a very normal file extension, never expecting that it may contain something that will destroy the computer. So please remember not to open some files that come from unknown resources. 

So how to prevent the danger that comes from SHS files? Here it what you should go: go to Start -> Run -> type Regedit to open Registry Editor -> locate HKEY_CLASSES_ROOT\.shs and then delete the default “ShellScrap” value. Hence, when running a shs file, it will pop up a window asking you to select the program to open the files. 

With the method above, you can protect your computer data against some unknown malwares or viruses and then optimize PC performance. But to more effectively optimize PC performance, it is necessary for us to regularly run a disk defragmenter with the below reasons. 

When using the computer, no matter what it is used for, there will be the entries to the hard disk. If the hard disk is fragmented because of the disk fragments, it will overload the movement of the hard disk head, slowing sown the computer and then shortening its lifespan. 

So to optimize PC performance, it is necessary for us to take some very simple measures like disk defragmentation to always keep everything in the hard disk storing in order coherently. Hence, it will essentially speed up the computer and optimize PC performance.
