Windows 10: Slow Google chrome after changing Priorities in Task Manager

I changed the priorities of Chrome to "low" in Task Manager since I didn't think it will affect anything. Before, it was running at normal speed, but after I changed, it became incredibly slow, some sites could not even run properly.I tried changing back the priorities back to "normal" but it still automatically become "low". I also tried using Process Lasso a friend recommended, still none was working.

Google Chrome Crahses and suspended in task manager

Hi GSsswuw8,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. Do you have any antivirus installed on the computer?
   
2. Are you aware of making any changes to the computer or browser prior to the issue?
   

This issue is because of profile data corruption on google chrome or because of cookies, extensions, plugins and History. I would suggest you to follow the steps mentioned below to resolve this issue.

Method 1: Rename Google chrome file.


Before proceeding I would suggest you end all the task related to Google Chrome from task manager.

Step 1: Rename Chrome User Data file.

1. Press Windows and
   E key together on your Keyboard.
2. Navigate to %LOCALAPPDATA%\Google\Chrome.
   
3. Search for User data folder. Rename this folder to UserData.old
4. Open the chrome now and check if it is working.
   

Note:
The new user data folder will be created automatically, but
new profile will not have any of your previous data in it. To access the data back, try signing out and signing in back to the application. Or you have to manually copy the data from old profile.

Step 2: Copy the previous data to New Profile.


I would suggest you end all the task related to Google Chrome from task manager.
Then follow the steps mentioned below:

1. Press Windows and
   E key together on your Keyboard.
2. Navigate to %LOCALAPPDATA%\Google\Chrome\UserData.old\Default.
   
3. Open a new tab and navigate to: %LOCALAPPDATA%\Google\Chrome\User Data\Default. (Make sure this is the new user data folder)
   
4. Now copy the file one by one, once the copy is done. In-between Reopen Chrome browser and check if there is issue same issue.
   
5. If the issue reoccurs, then the culprit is one of the file copied above.
   

Method 2:
Troubleshoot on google chrome.

Note: The Uninstall and Reinstall option might reset security settings or privacy settings that you added, this will also clear the history, favorites, cookies and password. We recommend
that you note these sites and settings before you use the Reset on chrome.

I would suggest you to follow the steps mentioned in the article on
Fix Chrome if it crashes or won't open.


Hope it helps.

problem uninstalling google chrome

Hi,

Since you already uninstalled Google Chrome using the Programs and Features, Google notifications may still be running in the background processes. We suggest that you follow these steps on how to end the Google Chrome process:

• On your keyboard, press Ctrl+Alt+Delete.
• Select Task Manager.
• Under Processes, locate Google Notifications or Google Chrome.
• Right click on them and select End Task.
• Double check under Programs and Features if Google Chrome is completely gone.

Let us know if these steps worked.

 

Can't change priority in Task Manager

Here is something which might help:

Unable To Change Process Priority On Windows 11 22H2 - Super User

Changing the priority in Task Manager may not stick for several reasons, mostly if the executable restarts itself. It then loses all attributes and starts again with the default ones.

To permanently set the priority of a process, do this :

• Find the name of the executable, say PROGRAM.EXE
  
• Create a Text Document with .reg extension and enter the following:
  
  
• Replace PROGRAM.EXE with your application and change the PRIORITY to one of the following values:
  
  
• Double-click to execute the .reg file and click Yes and then OK
  

To undo this change, delete the registry key that you added.

In addition to the CpuPriorityClass value, also exists IoPriority with the same numerical values as above, except that 0 stands for Very Low and the values 5 and 6 don't exist.
