If you've applied a major update to Windows 10 recently, you might notice that a couple of your apps have gone missing. It's not a bug. Windows 10 is removing apps it considers incompatible or outdated. As tech site the How-To Geek points out, critical Windows 10 updates (like the big November update) sometimes remove apps from users computers. On my own machine, I found that system information tool Speccy was no longer on my computer. Other users are reporting that apps including CCleaner, HWMonitor and CPU-Z are also missing after an update.
It's unclear why Windows is doing this right now. While the primary theory is that the upgrade is removing outdated apps and drivers, Microsoft hasn't officially commented on the reasoning behind it. For now, if you want your apps back, you'll have to reinstall them manually. Check out the How-To Geek's post for more details on how to potentially recover your files as well.
