Win10 the solution to the problem of slow reaction in the blank space of right key

We can right click on the lower left corner of the computer, click "Run" as shown in the following figure, or press Win+r to open the Run box

In the Run box we fill in the Regedit, click OK

Then click on the HKEY_CLASSES_ROOT below, this is on the left side of the registry, as shown below

And then in the open we'll find hkey_classes_root\directory as shown in the following figure

Then we double click in and navigate to hkey_classes_root\directory\background\shellex\contextmenuhandlers.

Finally delete the contextmenuhandlers in the folder except new

There is a possibility, in addition to the new will also have a delete, but it does not matter, try the right button on the desktop, to see how fast, not yet, after the restart on the line
