Your
computer
is hanging. Same old Windows, right? Except you’re using a brand new
Windows 8.x or Windows 10 device, you’ve only had it a few days. So just
what is going on?
Investigating, you discover that your system drive is running at
100%. Surely this can’t be right? Sadly, it is. The latest versions of
Windows have a problem with the drives being over worked, which slows
down the operating system. This issue affects both hard disk drives
(HDDs) and solid state drives (SSDs).
Several fixes are available for this, depending upon what exactly is causing the problem.
Slow Performance? Check Your Disk Usage
This performance issue is most obvious when attempting to use
Search
(Windows key + Q) to find a file or program, and anything else that
requires the drive to do some work (perhaps copying and pasting a group
of files).
To establish whether it is a problem that is affecting you, when your computer next slows down press
CTRL+ALT+DEL and select
Task Manager. (Alternatively, right-click the
Taskbar and select
Task Manager.) Note that this may take some time to open with the drive being slow.
On the first tab,
Processes, look for the
Disk
column. If you’re having problems with drive performance, this should
be at 100%, and colored red to indicate whether you have a problem or
not.
Once you’ve found there is a problem, you have several options available.
Check Your Anti-Virus Software
If threats are found, use the software’s recommendations to discard
them, and reboot, before checking your drive performance further.
Hopefully you’ve resolved the issue; if not, then malware wasn’t to
blame, so read on.
Disable Windows Search for Improved Disk Performance
The next thing to check is whether the problem is to do with Windows
Search. A bug in Windows 8 and 10 results in a sort of “search loop”
that results in an increased load on the system drive.
net.exe stop "Windows search"
To permanently disable Windows Search or Indexing, press
Windows + R, enter
services.msc, and hit
Enter. In the
Services window that opens find the
Windows Search entry and double-click it to open the
Windows Search Properties window. Under
Startup type, select
Disabled. Here you can click
Stop to abort the service. Click
OK to save your changes.
A few moments after disabling Windows Search, your Windows 8.x or
Windows 10 performance should improve considerably. If not, move on…
Disable Superfetch Service
For some reason, the superfetch service has been identified as a
potential cause of these disk performance issues in Windows 8.x and
Windows 10. To deal with this, open another Command Prompt (or if you’ve
still got the earlier box open, use that) and enter:
net.exe stop superfetch
Again, wait a few moments to check whether this has had any effect on
your computer’s performance. You should also run Check Disk in a
Command Prompt:
chkdsk.exe /f /r
You’ll be informed that your PC must be rebooted for Check Disk to
complete, so make sure you have closed all of your applications first.
If this doesn’t work, it is likely that you’re experiencing an
iteration of this issue that is frustrating to realize, but simple to
resolve.
Could It Be Flash?
In Chrome, go to the address bar and enter:
chrome://plugins

Click the
Disable button; the Adobe Flash Player
entry will be grayed out. Wait a few moments and then check your Task
Manager. Performance issues related to your system drive should be
resolved. Try restarting the Chrome Browser if this is still an issue.
Disk Usage Should Rarely Be 100%
Put simply, there is little reason for your disk load to be anything
close to 100%, certainly not under normal usage. A slow computer is one
with a problem, and if you cannot fix it by disabling a browser plugin,
stopping services, or running your anti-virus software, then the problem
may well be hardware related.
Perhaps your drive is getting old; it may be
defective, or the cables may need replacing. Alternatively, there is a
chance that the problem is connected to the Windows defrag tool. If your
computer is attempting to defrag your drive, but your HDD is actually
an SSD, then
serious problems can occur. Deal with this by opening the
Task Scheduler (WINDOWS + Q, enter
task scheduler) and disable any scheduled disk defrag tasks.
