Even if the uploader had good intentions (e.g., privacy-focused tweaks), running an unsigned, community-modified OS is extraordinarily dangerous. Here is why:
Since this is the "April 2018 Update," it introduced several features that were considered major upgrades at the time. If you are using this for a specific purpose (like running older software or a low-end PC), these are the highlights:
A. Timeline (The Biggest Feature of RS4) This build introduced Timeline via the Task View button. It allows you to scroll back through your activity history (files opened, websites visited, apps used) by days or weeks. It effectively works like a "time machine" for your productivity, syncing activities across other Windows 10 PCs if enabled.
B. Focus Assist (Quiet Hours) This was the rebranding of "Quiet Hours." It allows you to suppress notifications automatically based on rules (e.g., when you are duplicating your display for a presentation, or during set "focus" hours). It is very useful for minimizing distractions while working.
C. Near Share (Bluetooth File Transfer) This build introduced a native "AirDrop" style feature. You could right-click a file and share it via Bluetooth to a nearby PC. This was a lightweight way to move files between laptops without USB drives.
D. Native FLAC and HEVC Support RS4 improved native support for media formats. It had better built-in support for FLAC audio and high-efficiency video coding (HEVC/H.265), which meant you often didn't need to install third-party codec packs (like K-Lite) as frequently.
E. Reduced "Bloatware" (Pre-Activation Aspect) The "v3 prea" tag suggests this is a modified ISO. Custom ISOs from 2018 were often popular because they were "stripped" or "lite" versions. They often removed Windows "bloatware" like the original Candy Crush, Twitter, and Xbox apps that Microsoft forced into the Start Menu. This made the installation cleaner and slightly faster on older hardware.
Many scene releases apply aggressive registry "optimizations" that cause:
Using a pre-activated copy violates Microsoft’s EULA. While Microsoft rarely sues individuals, the software itself may be considered unauthorized, and you cannot legally obtain updates or support.
Instead of risking a July 2018 pre-activated release, use Microsoft’s official sources:
That specific filename is not safe, not official, and not worth the risk. Using it exposes you to malware, legal issues, and security vulnerabilities — all for an outdated operating system that Microsoft no longer supports. Even if the uploader had good intentions (e
Do this instead:
Your digital safety is more important than a pre-activated shortcut.
