Every once in a while you may have definitely encountered a problem where one particular application uses 100% disk usage (or CPU, or memory usage). Many users reported “high disk usage” problem on their systems when Google Chrome is launched. Chrome may totally stall your system showing the status “waiting for cache”.
This post tells you how to fix the Google Chrome 100% disk usage problem in Windows.
Fix Google Chrome High Disk Usage Problem
First, make sure that your Google Chrome is up-to-date. The disk usage problem may have been fixed in a recent release. While Chrome updates automatically using Task Scheduler, it’s advisable to do a manual check.
chrome://settings/help to know if you’re running the latest release. If you already have the latest build and yet the problem happens, follow these steps one by one and see if that fixes the 100% disk usage problem.
Step 1: Use Chrome Task Manager
While in Google Chrome, press Shift + Esc to load the Chrome Task Manager. Chrome Task Manager shows the list of open web pages and Chrome Extensions that are running. For each entry, the CPU and memory footprint is displayed.
Step 2: Turn off Preload pages for faster browsing and searching
While the high disk usage (usually 100%, as reported on Task Manager’s Processes tab) is mostly caused by some bad programming practices, at the same time, the age of the computer hardware is to be blamed equally. Sometimes, newer features may not play well with old hardware. You can turn off a couple of settings (“prefetch” features) to reduce the disk usage by Chrome.
- Start Google Chrome, and open Settings (
- Scroll down and click “Advanced” to expand the section.
- Under “Privacy and security”, disable the toggle button for “Preload pages for faster browsing and searching”. Note that in Chrome versions earlier than v73, this option was called “Use a prediction service to help complete searches and URLs typed in the address bar.”
- Also, disable the setting “Use a prediction service to load pages more quickly”
- Close and reopen Google Chrome.
Here is the explanation for the prefetch settings, by Google.
Preload pages for faster browsing and searching: Browsers use an IP address to load a webpage. When you visit a webpage, Chrome can look up the IP addresses of all the page’s links and load the ones you might navigate to next. If you turn this setting on, websites and any embedded content that are preloaded can set and read their own cookies as if you had visited them, even if you don’t.
While these Page prefetching / Link prefetching or prediction features help you load subsequent linked webpages quickly, they not only consume extra bandwidth but also additional CPU/Disk usage cycles.
Step 3: Turn off address bar autocomplete
Turn off autocomplete for search/address bar by visiting
Under “Other Google Services”, turn off “Autocomplete searches and URLs” setting.
Step 4: Disable Unwanted Chrome Extensions
See if browsing the same set of websites using Google Incognito (private browsing) mode helps. This mode loads Chrome without extensions and saved cookies are not utilized. If everything works fine in Incognito mode, then open Extensions settings page (
chrome://extensions/) and disable 1st half of the extensions. Close Google Chrome, reopen it and observe if the problem repeats.
If the problem recurs, disable the 2nd half of the extensions, close and reopen Chrome. In case that solves the problem, you’ll need to narrow down which particular extension in that 2nd half is causing the problem and eliminate the offending extension.
Step 5: Reset Google Chrome
If disabling the prediction services and Chrome Extensions did not help, you may reset Chrome completely in an attempt to fix the disk usage problem. These are three ways you can reset Google Chrome:
- Reset Google Chrome via Settings
- Reset Google Chrome Using Chrome Cleanup Tool
- Reset Google Chrome completely by deleting its data folder
Each method is covered in detail in article Reset Chrome Browser to the Default Settings.
Note: If you’ve your account data synced with Google servers, the data should be back once you log in to Chrome after resetting. However, it’s prudent to have local backup copies before resetting, just in case.
That’s it! I hope the article helped you resolve the high (100%) disk usage problem in Google Chrome on Windows.
