Fix: Dragging windows not smooth after upgrading to Windows 8.1

In our past, we have told you how you can tweak the visual effects to enhance your system performance. Although you can tweak the system to show no content while dragging, or even disable drag and drop, what if you find that dragging isn’t smooth anymore on your system. This is the issue which we have came around yesterday after upgrading to Windows 8.1. In the course of this problem, we found that while we drag content from here to there, the movement of the cursor is not as smooth as it should be.

Initially, when we faced this issue, we thought that it might be a driver issue. So we updated the display adapters but it made no differences in the situation. The issue is resultant of nasty frame rate-aliasing effects since there is less refresh rate for the monitor.

To fix this problem, you can try following fix:

Dragging windows not smooth

1. Press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.

REGEDIT Fix: Target of Internet Shortcut is not valid error For IE

2. Navigate to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers


3. In the right pane of this location, right click on the blank space and select New -> String Value. Name this newly created string as C:\Windows\explorer.exe where C: is essentially the system root drive. Now double click on the same string to modify its Value data:


4. Put the Value data to NoDTToDITMouseBatch. Click OK. You may now close Registry Editor. Now open the administrative Command Prompt and paste following command there followed by Enter key:

Rundll32 apphelp.dll,ShimFlushCache


Finally, reboot the system and your issue should be fixed by now.

Hope this helps!
