Win7 file can not be copied Paste keyboard and mouse are invalid solution

Win7 system copy and paste is estimated to be a small series of operations that should be touched every day, using the mouse, keyboard can be completed quickly. However, today Xiaobian encountered a strange thing, after copying the folder, but can not paste, the keyboard can not be pasted, the right mouse button paste option has also become gray, what is the matter?

First, I thought that it might be that the installation software caused the Win7 system to be poisoned. If it is computer poisoning, you need to kill it or go directly to the safe mode for antivirus. After the anti-virus, Xiaobian found that it is still impossible to paste. At this time, it may be necessary to enter the computer disk for cleaning.

Second, right click on the system C drive, select Properties, and then select Disk Cleanup in the Open C drive properties window. The remaining disks will be cleaned up.

Third, click on the Win7 desktop start button and select the Run dialog box from the Start menu. Then enter the CHKDSK D:f command in the Run window to clean up the system disk.

After restarting the Win7 system, the copy and paste function is also restored to normal use. If you still think that the manual solution is too much trouble, you can directly download the 360 ​​security guards, directly search for the problem of copying and pasting in the computer clinic, the software will help you automatically fix it. Of course, the probability of solving this method is not necessarily high. If you want to solve it completely, you need to manually operate it.
