This revision looks good on paper, but it has some serious flaws. KB5026372 is, according to feedback in our discussion forums and Reports on Reddit. For instance, there have been reports of issues with VPN connections, especially L2TP/IPsec VPN. L2TP is commonly used by businesses to enable VPN connections for their customers, and it does so by employing an encryption protocol.
Some users have reported a significant slowing of transfer speeds, while others have had trouble downloading files via sftp while connected via an L2TP/IPsec VPN.
Users told us they had tried reinstalling WAN, flushing DNS, turning off IPv6, and even turning off the Windows Firewall, but none of these measures had any effect.
An additional user mentioned that they were forced to perform a full wipe and Windows reinstall after BitLocker activated as a result of the update and the subsequent automatic repair loop. Some users have also reported that after installing the updates, Windows shut down without prompting them to do so.
Because of these issues, many users are frustrated and looking for workarounds, which raises questions about the update’s stability and reliability.

In addition, despite months of effort, the TPM detection and core isolation settings continue to be unusable. Due to this, some of you may receive an The local security shield is down. Your gadget could be at risk. Please try the following if you continue to receive Windows Security warnings:
- Launch RegEdit.exe to access the registry.

- In the registry, edit the Lsa key so that its value reads “RunAsPPL” =dword:00000001. An LSA feature configuration UEFI variable will be set up. To configure this feature without a UEFI variable on Windows 11 22H2, use “RunAsPPL” =dword:00000002.
