What is KB2952664?
KB2952664 is a Windows update released by Microsoft for Windows 7 systems. It was first introduced in 2014 and has been re-released multiple times in slightly different versions.
The purpose of this update was to prepare your Windows 7 PC for an upgrade to Windows 10. In more technical terms, KB2952664 was designed to improve the Windows Update process and compatibility checking tools. It helped Microsoft collect data on whether your system could handle the upgrade smoothly.
So, in simple words:
KB2952664 helps your Windows 7 computer get ready to upgrade to Windows 10.
What Does KB2952664 Actually Do?
Let’s break it down further. Here’s what the KB2952664 update does behind the scenes:
- It installs software that checks your hardware compatibility
- It collects system information like drivers, installed programs, and performance data
- It sends this data to Microsoft to analyze if your PC is ready for Windows 10
- It makes changes to improve how future updates are delivered
This update does not install Windows 10 automatically, but it lays the groundwork by preparing your system for the upgrade.
Is KB2952664 Safe?
Yes, KB2952664 is safe, at least from Microsoft’s perspective. It does not harm your computer, steal your personal data, or break anything directly. It was released as an optional update, not a critical one.
However, some users were concerned that:

- It keeps trying to encourage Windows 10 upgrades
Because of this, some users call it “nagware” or “telemetry software” and choose to uninstall it.
