The latest Patch Tuesday brings a new batch of security updates addressing a total of 117 vulnerabilities
The second Tuesday of the month is here, which means that Microsoft has rolled out patches for security vulnerabilities in Windows and its other products as part of its monthly Patch Tuesday bundle. This month’s batch of security updates brings fixes for no fewer than 117 security vulnerabilities including four security loopholes that are being actively exploited in the wild according to Microsoft.
Of the grand total, 13 security flaws have received the highest severity rating of “critical”, meanwhile 103 were classified as “important”, and it’s worth noting that six security bugs are listed as publicly known at the time of the release.
The PrintNightmare zero-day, which received an out-of-band update recently, is one of the four actively exploited security flaws. Indexed as CVE-2021-34527, the remote code execution vulnerability resides in the Windows Print Spooler service and affects all supported versions of the Microsoft Windows operating system. Successful exploitation of this flaw enables remote attackers to run arbitrary code with SYSTEM privileges on the vulnerable system and could allow them to completely take over.
The next actively exploited vulnerability on the list is a remote code execution bug found in the scripting engine. Tracked as CVE-2021-34448 it holds a score of 6.8 out of 10 on the CVSS scale and is rated critical. “In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability,” said the Redmond tech titan. However, for the flaw to be exploited an attacker would have to dupe the user into visiting the website, by sending them a link either via email or direct message and then convince them to open the file.
Security updates have been released for a wide range of products, including Microsoft Office, Exchange Server, Visual Studio Code, as well as other products in Microsoft’s portfolio.
All updates are available via this Microsoft Update Catalog for all supported versions of Windows. Both regular users and system administrators would be well advised to apply the patches as soon as practicable.

This month’s update rollout event also brought some problems to the surface, that started after users installed the latest batch of cumulative updates.
And, as you would expect, this kind of triggers a neverending chain of events, where the future patch fixes problems with the current one, and so on.
These are the problems that Windows 10 users noticed after downloading and applying the latest cumulative updates.
This is the first issue to emerge out of the depths of social media, where Windows users usually inform others of their ordeals.
Apparently, after installing KB5004237, which is an update released by Microsoft as a part of the July Patch Tuesday event, for 2021, things went a bit crazier than expected, as Reddit user GiliamOS exemplified.
After rolling out the two patches to a batch of test machines, connecting to them via RDP you see a corrupt connection. It works, but is visually unusable. Rolling back the patches fixes it, but come on Microsoft!
Anyone have ideas post-patch install how to fix this? Changing color depth, res or “experience” makes no difference.
At first glance, it seems that the cumulative updates entered some sort of conflict with the display drivers that he had installed on his device.
The post’s author even confirmed that, after checking, he realized that the driver version he had installed, came from Microsoft, instead of Nvidia.
There aren’t that many reports of users dealing with the same issue, just yet. And this is because there are some patches that affect different users in different ways, while some cause the same problem for everyone involved.
We will keep an eye out and monitor the situation, while also keeping you informed on any new details.
Another user complained on the Microsoft Answers website that he is unable to charge the battery of his Dell Precision 7530 laptop after installing the new KB5004237 patch:
So this thing started happening recently when battery wont charge, but the time remaining is shown in this manner when the charger is plugged in. Is this a cause of concern?
Additional information about the system: Dell Precision 7530, barely an year old. The laptop is able to boot up on battery power i.e when the charger is not connected to the system.
In the screenshot provided by the user below, you can see that when he is connecting his charger, the battery is not showing that it’s charging but the remaining time for battery energy is extremely high.
Apparently, he already tried a lot of procedures like disconnecting the power supply and battery and reconnecting them, performing a BIOS update, reinstalling the battery drivers, and performing the Power troubleshooter to no avail.
Unfortunately, we have no official solution from Microsoft about how to circumvent this problem. We will monitor this issue and get back to you with a solution as soon as possible.
After installing the new KB5004237, a user is complaining on Reddit this time that his system was set on the Marlett font and he can’t read anything anymore:
The last Windows 10 update really messed up my fonts in Windows. Noticed it immediately in my email program. Tried to install dot net, and those fonts were messed up as well on the install screen. Now noticing that right click menus on the desktop are the same way, as well as file and folder names. It’s all gibberish. Any suggestions? Can’t do screenshots because Windows 10 is largely useless, although some programs are okay. Where there should be readable text, there’s just garbage. Programs like Edge work fine so far, or Skype.
Now, if you’re checking the Marlett font, you will see that it is a true-type font developed by Microsoft and used since Windows 95 used for user interface icons from menus and windows.
Definitely, it cannot be used for any text and can be seen as gibberish even for a more trained eye.
Unfortunately, we don’t have any official feedback from Microsoft and there is hardly anything to do unless you know your way precisely to uninstall the patch from the update history.
We will keep an eye on the development of the situation and update this article as soon as there are new developments.
After finishing an automatic repair triggered by the system, a user reported on Reddit that he received the error 0x8007000d after installing the KB5004237 update.
Hello everyone! Yesterday my laptop booted up to repair screen automatically. I think the EFI partition was damaged or something. I managed to fix by formatting it. Now when I want to update Windows to KB5004237 I get error 0x8007000d. I tried SFC /scannow and it fixed some things. I then ran DISM which also fixed some things. But I still got the error. I tried resetting the Windows Update components, but that also didn’t work. I tried the in-place upgrade but that also failed. Can anyone help me?
The error 0x8007000d appears when the system can’t find an essential file in the installation package.
Corrupted system files and broken Windows update components are some of the reasons why you may encounter this error.
Fortunately, we have an excellent guide on how to fix the Windows Update error 0x8007000d so after performing the indicated steps, you should be fine.
