Weird bug where system specific things are very slow.

agrzesiak · 09 Dec 2016

This started a couple months ago but I found a hack where if I open a program and it asks for admin privileges it would magically go away. Anyways, a couple examples of what's happening is hovering over an icon in the tray takes a couple seconds to illuminate showing it is being hovered over. Right clicking opens the border of the little window but it takes a couple seconds to populate with the options. Using task manager is painfully slow. In windows explorer, it takes a couple seconds to show a file or folder is being hovered over. Like I said I found a hack for this but I would like to find an actual solution. Thanks.

Welcome to the forum.

With regards to right clicking. The little menu window is called your context menus should you wish to research further within the forum and google.

You likely have to cleanup / adjust what is in your context menu. See this thread.

'Properties' option not accessible in Right Click Menu

As to admin privileges ... this sounds like UAC - User Account Control. Are you trying to disable it or you just don't want the prompt. Did the "hack" you found just disable UAC?

As an overall check you could run sfc /scannow from a Command Prompt Run as Administrator.

I don't think it has anything to do with various added options in the menu. The hack I found was as simple as just opening a program that asks for admin privileges. I don't even need to click yes for the oddity to go away.

Hi, Do you see the same delay in Safe Mode?

I'd agree with Caledon Ken that the first thing to try (it's quite easy) is the effect of disabling all context menu entries just to see if any of them is giving rise to a problem. Hoping for an instant 'fix' as an obscure 'hack' to solve an issue arising in using file explorer like this really isn't the way to go.

Download install and run Shellexview (easy to find, free), hide all MS entries (very important) and disable all others. Then compare performance.

If improved, identify the culprit. If no change, also try a clean boot and check again.

Finally re-enable them and post back.

Please post a screenshot of your task manager when your PC is nominally idle.

The menu glitch is just one symptom. There is slowness associated with everything to do with the built-in features: scrolling, windows explorer, changing colors when hovering, etc. I will boot into safe mode later and see if that helps. I will also do a before and after pic of the task manager.

Have you opened a command prompt as Administrator and run SFC /Scannow

.. try Safe Mode first - that's easier. If your system is responsive then, it's more likely to be sthg installed. If it's not, you have other problems, and I would start with

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Make sure the result is clear or fixed- else do not proceed.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

and then
SFC /SCANNOW
from a an admin command prompt.

Note: it's relatively common that this fails, and a failure is probably unrelated to your system being slow, but worth doing as a basic starting point.
