KB5043145 Microsoft Windows 11 Update: Issues And Fixes

Microsoft recently released an optional update for the Windows 11 operating system, labeled KB5043145. This update was intended to introduce new features to the Start menu, Taskbar, and Lock screen. However, for some users, the update has led to various PC malfunctions, causing frustration and inconvenience.

Reported Issues

Blue Screen of Death (BSOD) and Green Screen of Death (GSOD)

After installing update KB5043145, some users reported encountering the dreaded “Blue Screen of Death” (BSOD) when attempting to reboot their computers. In less common cases, users experienced a “Green Screen of Death” (GSOD). These issues prevent the normal startup of the operating system, leaving users unable to access their PCs.

Endless Loading Loop and Automatic Recovery

In addition to the BSOD and GSOD, some users found their computers stuck in an endless loading loop after installing the update. When attempting to fix or reset the update, the operating system’s automatic recovery function would launch, but fail to resolve the issue. One user shared their experience:

“After installing KB5043145 and rebooting, my laptop got stuck on the manufacturer’s logo screen with an endlessly spinning loading circle (endless = 20 minutes). I had to press and hold the laptop’s power button, and only then did Windows 11 launch the recovery function. Fortunately, it worked. However, the update is now not installed. My Windows 11 has all the latest updates (version 23H2, 22631.4169) and all the latest drivers.”

BitLocker Recovery Issues

Some users also reported issues with the BitLocker recovery feature after installing the update. BitLocker is a built-in encryption feature that helps protect data on the device. In some cases, users were prompted for their BitLocker password to restore functionality, adding another layer of complexity to the already frustrating situation.

Microsoft’s Acknowledgment and Investigation

Microsoft has acknowledged that they are aware of the problems caused by the KB5043145 update. According to the company, all PCs running Windows 11 23H2 and Windows 11 22H2 may be affected. As a result, Microsoft has rolled back the release of the update to prevent further issues.

In a conversation with Windows Latest, a Microsoft support representative confirmed that they are investigating the issue. They stated that affected machines initiate the automatic OS recovery function after users encounter BSOD and GSOD several times when booting their PCs. Additionally, the BitLocker password may be required to restore functionality if it is set up.

Additional User Complaints

Apart from the major issues mentioned above, some users have reported other problems after installing the KB5043145 update:

Non-Functional Mice and Keyboards

Some users complained about non-functional mice and keyboards after installing the update. The USB ports to which these devices are connected appear to be unresponsive, preventing users from using their input devices.

Loss of WLAN Connectivity

Another issue reported by users is the loss of WLAN connectivity after installing the update. This can be particularly frustrating for those who rely on wireless internet connections for their work or daily tasks.

Windows Subsystem for Linux (WSL) Malfunction

Some users noted that the Windows Subsystem for Linux (WSL) stopped working after installing the KB5043145 update. WSL is a feature that allows users to run a Linux environment directly on Windows, without the need for a virtual machine. The malfunction of this feature can be a significant setback for developers and users who rely on WSL for their projects or workflows.

What to Do if You’re Affected

If you have encountered problems after installing the KB5043145 update, Microsoft urges you to contact their support through the Windows “Feedback Hub.” This will help the company gather more information about the issues and work towards finding a solution.

For those who have not yet installed the update, it is important to note that installing KB5043145 is not mandatory. This update is an optional release for participants in the Windows Insiders program, distributed through the Release Preview channel. Therefore, you can choose not to install this update until the issues are resolved and the update appears in the general release channel in the “Windows Update” center.

If you have already installed KB5043145 and are experiencing problems, you can remove the update via the Windows Recovery function. To do this, follow these steps:

Access the Windows Recovery function by restarting your PC and interrupting the boot process three times.
In the “Choose an option” screen, select “Troubleshoot.”
Click on “Advanced Options.”
Select “Uninstall Updates.”
Choose the KB5043145 update and click “Uninstall.”

After removing the update, Windows should be able to reboot correctly. Even if you are not experiencing any problems after installing the update, it is still recommended that you remove it as a precautionary measure. You can also uninstall the update through the Windows “Update History” if your PC is functioning normally.

10 Rules to Avoid Online Scams

Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.

Stop and verify before you click, log in, download, or pay.

Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).

If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.

Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.

If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.

Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.

If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.

Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.

If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.

Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.

If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.

Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.

If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.

Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.

If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).

Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.

If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.

Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.

If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.

Move quickly. Speed matters for disputes, account recovery, and limiting damage.
- Stop payments and contact: do not send more money or respond to the scammer.
- Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
- Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
- Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
- Scan your device: remove suspicious apps or extensions, then run a full malware scan.
- Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
- Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.

These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
