On Friday, July 19, 2024, morning, reports surfaced globally of Microsoft Windows operating system users encountering the infamous Blue Screen of Death (BSOD) following the latest update from CrowdStrike. This widespread issue has severely impacted critical services, including telecommunications, banking, airline and railway operations, supermarkets, hospitals, and major news networks.
CrowdStrike has outlined a four-step process for regaining access to Windows PCs affected by the update:
For cloud environments, customers can revert to a snapshot taken before 4:09 am UTC.
For AWS (Amazon Web Services), follow these steps:
For Azure, follow these steps:
The manual nature of this fix poses a significant challenge for companies, especially those without backups for all VDIs, potentially slowing down the recovery process. Customers will also need a recovery key to access Safe Mode if Bitlocker is enabled on the system disk.
CrowdStrike Engineering has reversed the changes causing this issue, with the error code displayed on affected systems: “Tech-Alert-Windows-crashes-related-to-Falcon-Sensor-2024-07-19.“

To avoid this error or recover from this failure, please follow the Instructions to manually resize your partition to install the WinRE update and then try installing this update.
Or, to use a sample script to increase the size of the WinRE recovery partition, see Extend the Windows RE Partition.
Windows Server 2022
This update automatically applies Safe OS Dynamic Update (KB5034235) to the Windows Recovery Environment (WinRE) on a running PC to address a security vulnerability that could allow attackers to bypass BitLocker encryption by using WinRE. For more information, see CVE-2024-20666.
NOTE If your running PC does not have a WinRE recovery partition, you do not need this update. To verify if you have WinRE enabled, you can run the following command in an elevated command prompt: reagentc /info
If WinRE is enabled you will see Windows RE status in the output with a value of Enabled.
| IMPORTANT This update requires 250 MB of free space in the recovery partition to install successfully. If the recovery partition does not have sufficient free space, this update will fail. In this case, you will receive the following error message: 0x80070643 – ERROR_INSTALL_FAILURE To avoid this error or recover from this failure, please follow the Instructions to manually resize your partition to install the WinRE update and then try installing this update. Or, to use a sample script to increase the size of the WinRE recovery partition, see Extend the Windows RE Partition. |

This tutorial on how to block a program in a firewall applies to computers running Microsoft Windows 11 operating system. Some details might vary slightly for Windows 10 or older versions, but the procedure is essentially the same.
Use one of the following methods to open the Windows Defender Firewall with Advanced Security.
Choose whether you want to set an inbound rule allowing access to your computer for an external application or program, or an outbound rule allowing an application or program installed on your computer external access through the firewall.
The program-blocking process is similar for both types of rules—for this example, we’ll choose Outbound Rules to block a program in the firewall.
Select the appropriate option from the left sidebar of the Windows Defender Firewall with Advanced Security screen. A list of outbound rules appears detailing their names, groups, profiles, and status (enabled/disabled).
In the sidebar to the right of the list of existing outbound rules, click the “New Rule…” option. The New Outbound Rule Wizard opens, presenting four options for type of outbound rule:
Select Program and click the “Next>” button. The Program dialog box opens to ask whether you want this rule to apply to all programs or just one specific program.
To block a specific program, select the “This program path” option and click the “Browse…” button to open the program folder.
Locate and select the executable file (.exe) for the program you want to block.
Click the “Next>” button.
The Action window of the New Outbound Rule Wizard opens, presenting three options:
Select “Block the connection” and click the “Next>” button.
The Profile window of the New Outbound Rule Wizard opens, presenting three options:
Specify when the rule will apply and click the “Next>” button.
The Name window of the New Outbound Rule Wizard opens. In the empty fields, assign a name and description for the rule. Click the “Finish” button.
The Windows Defender Firewall with Advanced Security box lists all the existing outbound rules. Confirm that your new rule is included in the list. The program is now blocked; to unblock it, simply select and delete the rule.
You can unblock other programs the same way—to find them, sort the list by name, profile, state (enabled/disabled), or group and click Disable Rule in the right sidebar. You can also perform cut, copy, and delete rules or view their properties.
