Windows 10 has been out since July 29, 2015, so how many years has windows 10 been out depends on the current date, but as of 2026 it has been available for about 10 years and 5 months. If you are asking what year did windows 10 come out, the answer is 2015.
What year did Windows 10 come out?
Windows 10 was released by Microsoft in 2015. More specifically, it became generally available on July 29, 2015. That is the date most people mean when they ask how long has Windows 10 been around or how long has Windows 10 been out.
How many years has Windows 10 been out?
As of 2026, Windows 10 has been out for a little over 10 years. Because the exact number changes as time passes, the cleanest way to answer this question is:
- Release date: July 29, 2015
- Year released: 2015
- Approximate time out as of 2026: about 10 years and 5 months
If you are reading this in a different year, subtract 2015 from the current year, then adjust for whether July 29 has already passed.
How long has Windows 10 been around?
Windows 10 has been around since mid-2015, so it has been part of the Windows lineup for a decade. That is why you may see different answers online depending on whether the writer is using the calendar year, the exact release date, or the current date.
For example, if someone checks in:
- 2020: Windows 10 has been around for about 5 years
- 2025: Windows 10 has been around for about 10 years
- 2026: Windows 10 has been around for a little over 10 years
Windows 10 release date vs support status
It helps to separate release date from support status. A product can be out for many years even after its main support phase changes.
| Topic | What it means |
|---|---|
| Release date | The day Windows 10 became available to the public, July 29, 2015. |
| How long it has been out | The number of years since that launch date. |
| Support status | Whether Microsoft still provides updates and security support for a specific edition or version. |
So, when someone asks how many years has Windows 10 been out, they are usually asking about age, not whether the operating system is still supported.
Why the answer changes over time
This question is time-sensitive. Windows 10 does not have a fixed age, because the answer depends on the current date.
That is why you may see slightly different wording such as:
- Windows 10 came out in 2015
- Windows 10 has been out for 10 years
- Windows 10 has been around for more than a decade
All three can be correct, depending on when they are written.
Quick timeline of Windows 10
Here is the simplest version of the timeline:
- 2015: Windows 10 launches
- After launch: Microsoft continues updating it with new features and security fixes
- Later releases: Windows 11 arrives as the newer major version
This context matters because many people ask how long has Windows 10 been out while also wondering whether it has been replaced by newer Windows versions.
How to figure out how long Windows 10 has been out
If you want to calculate it yourself, use this simple method:
- Start with the release date, July 29, 2015.
- Compare it with today’s date.
- Count the number of full years that have passed.
- Adjust for whether July 29 has already happened this year.
This gives you the most accurate answer, especially if you need to know the exact age of Windows 10 for a report, article, or comparison.
Windows 10 in context
Windows 10 followed Windows 8.1 and became one of Microsoft’s most widely used desktop operating systems. It also served as the bridge between older Windows releases and Windows 11.
If you are comparing release ages, Windows 10 is now firmly in the later stage of its lifecycle, even though it remains a familiar system for many users.
