Hello Taekogae,
Sorry to hear you are having issues. Need to know more.
1) Windows version you have on. Please use Winver.exe for full version numbers
2) Windowblinds version you are using.
3) That screenshot too small to know what application was it from? Windows Explorer?
4) And if you are using WB Theme on those, what theme/skin is it?
Thanks
