我有很严重的强迫症，之前自己往电脑锁屏壁纸和背景里添加了同一张图片，现在越看越别扭，实在受不了了。找了好多办法，都没能把这张图片从锁屏壁纸和背景历史记录里删掉 ，有没有大神能教教我，怎么才能精准删除这张图片啊？
I have a severe case of obsessive-compulsive disorder. Previously, I added the same picture to both the lock screen wallpaper and the desktop background of my computer. Now, the more I look at it, the more uncomfortable I feel, and I really can't stand it anymore. I've tried many methods, but I still haven't been able to delete this picture from the lock screen wallpaper and background history records. Is there any expert who can teach me how to precisely delete this picture?
