Is it Safe to Download?

The short answer is: Use extreme caution.

Because these ISOs are modified by anonymous individuals, there is no guarantee of safety. Here are the primary risks associated with downloading "Delta Pro" or similar modded Windows builds:

1. Malware and Viruses: Modded ISOs are a common vector for distributing trojans, keyloggers, and cryptocurrency miners hidden deep within the system files.
2. System Instability: By removing components deemed "unnecessary," the modifier might break essential features. You might find that you cannot use printers, connect to Bluetooth devices, or use specific Windows features like System Restore or Windows Update.
3. No Security Updates: Version 21H1 is older. If the modder disabled Windows Update, your computer will be vulnerable to future security exploits.
4. Legal Issues: Downloading and using modded, pre-activated versions of Windows violates Microsoft’s Terms of Service.

Step 2: Verify the ISO Hash

A responsible uploader will provide a checksum. For Delta Pro v42, search for the correct hash in community forums to ensure the file hasn’t been tampered with (e.g., injected malware).
