Windows 10 Can Delete Programs Without Asking

Installing a major Windows 10 Update may lead to some missing programs from your computer. Windows 10 may actually delete some of your programs without asking. But don’t worry, you can get the back very easy.

While Microsoft has refused to make any comments on this matter, it seems that the update process is designed to remove any programs that are incompatible.

Windows will not remove any programs randomly and at random times, it will only remove programs that are not compatible anymore with the new “build” or new major version of Windows 10. Why only when there is a new “build” or new major version? Because these “builds” are not treated as simple Windows 10 updates. These “buildsupgrade the system to an entirely new version of Windows.

Windows, as a part of the upgrading process, will leave your old Windows build– files on your system drive in C:\Windows.old directory. In the Disk Cleanup application this in displayed as “Previous Windows Installation(s)”.

As we said before Windows will only remove the incompatible programs. So how does it decide on what to keep and what to remove?

Well, if a program is known to cause crashes, bugs or otherwise conflict with Windows, Windows will remove it to maintain a stable system. Even though Windows will remove some of your programs, during the major updates, you will still get the “All of your files are exactly where you left them” screen.

This feature was designed to aid the average Windows user, who might have installed programs that are outdated. While Windows will make sure that these programs don’t cause any problems, it doesn’t give any notice that it has deleted a program from your system.

Some of the programs removed by the first Windows 10 major update were hardware-related like CCleaner, HWMonitor. In some cases people claimed that Windows removed hardware drivers such as Intel Rapid Storage Technology and AMD Catalyst Control Center. In other cases people reported that the Upgrade removed programs like PDF viewers and anti-viruses. What is confusing is that the Windows Upgrade process removed these programs, but not from all computers that benefited from this upgrade.

Even though Microsoft has not made any comments regarding this, it is clearly stated in the Microsoft Services Agreement that, Microsoft may remove access to software of hardware.

What is the solution you ask? Simple: Just reinstall the programs removed by the Upgrade process.

All you have to do is visit the developer’s website and download the deleted program. In doing so you might also be getting the latest version of that program.

If the program you are installing conflicts with Windows, even in its latest version, keep in mind that it could be deleted after the next major update. You may need to reinstall it after each major update.

Windows 10 will keep your old Windows files for 30 days after an upgrade, just in case you want your program’s files back. These are stored in the C:\Windows.old folder as we mentioned before. It will allow you to roll back to the previous build of Windows 10 if it so happens that you have a problem.

Keep in mind that even though these files are stored in C:\Windows.old folder, you can’t just copy them to your current Windows version, because any registry entry that the program depends on might not be there anymore.

As long as you don’t delete the C:\Windows.old forder manually or by using Disk Cleanup, your old Windows version will remain available for 30 days.
