Hey folks! Been having trouble with your trusty 32-bit apps on Windows 10? Crashing, glitching, acting all wonky? You’re not alone! It seems a pesky bug in how Windows 10 uses the CreateWindowEx function is stirring up trouble for some 32-bit applications. Let’s dive in and figure out what’s going on and what you can do about it.

What’s the Deal with CreateWindowEx?¶

For the tech-savvy among us, CreateWindowEx is a crucial function used by applications to, well, create windows! It’s a fundamental building block of how apps visually present themselves. When this function misbehaves, it can cause all sorts of headaches, from minor glitches to full-blown crashes.

The Symptoms: Recognizing the Trouble¶

So, how can you tell if this is the bug haunting your system? Here are a few tell-tale signs:

• Sudden Crashes: Your 32-bit apps might crash unexpectedly, often without any clear warning.
• Weird Glitches: You might experience visual anomalies, like distorted windows or rendering issues.
• General Instability: The app might just act strange, behaving in ways it shouldn’t.

Microsoft is aware of this issue affecting some Microsoft Visual Studio extensions and the Bloomberg Professional service. So, if you’re experiencing problems with those, this bug might be the culprit.

Is Your Windows 10 the Culprit?¶

This bug has been linked to specific versions of Windows 10. To check if you’re running a potentially affected version (Windows 10 Fall Creators Update - Version 1709, build 16299.19 or 16299.15), follow these steps:

1. Click Start.
2. Go to Settings.
3. Select System.
4. Choose About.
5. Look under Windows specifications for your Windows version information.

The Workaround: Rolling Back the Clock¶

The most reliable fix for this issue, at least for now, is to roll back to the previous version of Windows 10. Think of it as a time machine for your operating system! Here’s how:

1. Click Start.
2. Head to Settings.

4. Choose Recovery.

Important Note: You’ve got a 10-day window after upgrading to utilize this rollback option. This process will keep your personal files safe and sound, but it will remove any applications and drivers installed after the upgrade. Any settings you tweaked will also revert.

What if Rollback Isn’t an Option?¶

If those 10 days have come and gone, don’t panic! Your IT support or helpdesk should be able to assist in restoring your computer to the earlier Windows 10 version. Before you reach out, it’s highly recommended to back up all your important personal files, just to be safe. You can also contact Microsoft Support directly, but again, back up your files first!

The Status Update: Microsoft’s on the Case!¶

The good news? Microsoft is aware of this bug and actively working on a permanent fix. They’ve promised an update in an upcoming release, so hopefully, this headache will soon be a thing of the past.
