That makes two (and counting?) Another Windows 10 1903 Cumulative update released 29-May-2019

 If you have updated to Windows 10 Feature update May 2019 you should check Windows Update for Cumulative update KB4497935.

If you are wondering why your machine has not yet been offered the Feature Update May 2019, it may be you have an USB or SD card attached. Some users were getting their system drive switched to A:   which is not good

iOS 12.3.1 released today May 24, 2019

 Fixes for Messages app and VoLTE calling

Windows Update issues yet again

 May 14 saw another Patch Tuesday update released.
 79 vulnerabilities addressed, 23 critical, 2 active in-the-wild and an Adobe patch for Edge.

 After the QC, and release to users - a problem has been found.

 The problem occurs when users wish to use an explicit restore point taken before applying the May 14 update. As mentioned the May 14 update is recommended due to the number and nature of the patches applied.

 If a user requests a system restore from one of the restore points taken before the May 14 update, the system may encounter a Stop error (0xC000021A) . The problem: driver restore order.

 A solution: The system should restart the Windows Recovery Environment (WinRE) after two failed reboot attempts. At the WinRE screen
Troubleshoot > Advanced Options > More recovery options > Startup settings
Restart now
Select "Disable driver signature enforcement"
Some users need to use the F7 key to see the setting.

Older Windows update urged

 Older versions of Microsoft's Windows Operating System, think Windows XP and Windows 7, are vulnerable to yet another malware attack. This attack can and does act like a worm - malware that duplicates itself computer to computer.

 Microsoft released patches and updates today for both XP and Windows 7. Windows 7 and XP are used in many external enterprise networks. If a user with XP or Windows 7 visits one of these sites, or has new or existing network connections to an infected site, their system could become infected.

WhatsApp update recommended.

 It has been in hacker news the past few days. WhatsApp, the more secure messaging and phone app for iPhone, Android, Windows Phone and WEB has vulnerabilities that allow others to infect mobile devices with malware. The vulnerability can be exploited by placing a phone call. No answering of the phone call is required.

 A patch was released 2 days ago. That "fix" was not a complete resolution of the problem. A fix was released in the past few hours. It took me a few tries to get an update on one iPhone.

 It is being highly recommended to update WhatsApp. If you have automatic updates enabled, best to check to ensure your WhatsApp is updated.

Windows update Tuesday

 Released today, 2nd Tuesday as normal
 79 vulnerabilities fixed/patched. 2 Adobe patches. Of the 79 vulnerabilities, 23 are classed as critical. Two of those are being exploited in the wild.

One ring Phone scam

 Reports from other regions of the U.S.  now reported in Texas.  A single ring, often at night. The one ring call may be repeated. The area code 222 or 232. These area codes are in Africa. If and when the called party calls back they will incur large charges on their next phone bill.

 The scam uses a victim's curiosity to solicit the call back. So don't.

Firefox browser and extensions

 Firefox is an alternative browser choice. A good choice, usually.

In the past few hours, any and all extensions loaded into Firefox stopped working.
Mozilla, the Firefox vendor, is aware of the problem and cause, but no fix available at the time of this post.

 If you have loaded and rely on extensions for protection. Be aware.
I would recommend using about:extensions or the Menu option to view extensions:

Note the extensions to re-add after the Firefox issue has been resolved.

UPDATE: The issue with add-ons and extensions has been resolved. I advise reviewing your extensions and their settings.
