Hello, Danny Attard
Welcome to the Microsoft Community.
Thank you for your feedback. I have carefully read the information and problem description you provided. You mentioned that your computer freezes when you open Event Viewer.
I understand that this problem is frustrating, but don't worry, you can also try the following methods to troubleshoot the error, which may help you.
Method 1. Clean up the Event Viewer log
Open Event Viewer (press Win + R, type eventvwr and press Enter).
In the left panel, expand "Windows Logs".
Right-click each log category (Application, Security, Settings, System) and select "Clear Log".
Note: Before clearing the log, you may want to save the log in case you need to refer to it later. After right-clicking the log category, select "Save and Clear".
Method 2. Perform disk cleanup and disk optimization
Press Win + R, type cleanmgr and press Enter.
Select the system drive (usually C: drive) and click "OK".
In the Disk Cleanup window, select the file types you want to delete, click OK, and then click Delete Files.
Open File Explorer, right-click the system drive, and select Properties.
On the Tools tab, click Optimize.
Method 3. Run SFC and DISM commands to repair system files
Press Win + X or right-click the Start button and select Command Prompt (Admin) or Windows PowerShell (Admin).
Enter and run the SFC command:
sfc /scannow
This command will scan all protected system files and replace damaged files. This process may take some time, so please be patient. DISM can repair problems in Windows image files and is the next step when SFC cannot repair files. Continue using the Command Prompt with administrator privileges. Enter and run the following commands:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
These commands will check and repair problems in the Windows image file. /RestoreHealth You may need to connect to the Internet to download and replace damaged files.
Method 4. If you have tried the above methods and the problem persists, create a new local account and test whether the problem persists.
Press Win + S to open the search bar.
Type cmd, then right-click "Command Prompt" and select "Run as administrator".
Enter the following command in the command prompt and press Enter:
net user username password /add
For example, to create a local account named newuser with a password of password123, you can use the following command:
net user newuser password123 /add
Method 5. Perform an in-place upgrade
An in-place upgrade is a method of reinstalling Windows. The principle of an in-place upgrade is to overwrite only system files while retaining the original system and user data, thereby restoring the normal use of the system. The detailed steps are as follows.
Visit the official Microsoft website, Download Windows 11
Use the installation tool to create a USB installation disk or ISO file.
Insert the USB installation disk or mount the ISO file, and then run setup.exe.
Select the "Upgrade this PC" option and click "Next".
Make sure to select the "Keep personal files and apps" option and click "Install".
The process may take some time, please be patient.
Disclaimer: Let's try to perform an in-place upgrade, which will refresh your Windows files and operating system without deleting files or applications. But if there is important data on the computer, we still recommend backing it up in advance.
