If you’re planning to install Windows 7 KB4343900 on your computer, read this quick post and then decide whether you still want to hit the ‘Check for updates’ button or not.

Many users complained about Blue Screen of Death errors after installing this patch. They also confirmed that entering Safe Mode and uninstalling the update helped them fix this problem.

Here’s how one user describes this issue on Microsoft’s support page:

In a recent Windows 7 Professional update, KB4343900 caused the blue screen of death after I restarted my computer. I managed to start the PC in Safe Mode and uninstalled the update and it is working well since then. Considering it is deemed as an important update, how can I reinstall the update without the blue screen of death reappearing?

Well, if you experienced similar issues and you want to play on the safe side, you can try to reinstall this patch once again.

If the BSOD errors persist, the best approach is to simply avoid installing the August Windows 7 Patch Tuesday updates altogether.
