Operating system installation files (ISOs) are already compiled and compressed. Standard data compression tools like ZIP, RAR, or 7z cannot drastically shrink a 3.5 GB Windows 8 ISO into a few megabytes without removing vital components.

No. Compression affects only the download and extraction phase. Once installed, the OS is identical to a full-size version (assuming no components were removed).

These files are frequently hosted on Google Drive due to its high-speed servers and ease of sharing.

This method treats multiple files as a single continuous data block, significantly improving the compression ratio for similar system files.

Because these ISO files are modified by anonymous third parties, there is no guarantee of their integrity. Malicious actors frequently embed malware, spyware, keyloggers, or crypto-mining scripts directly into the installation media. Once installed, these threats run at the root level of your computer, allowing hackers to steal passwords, log keystrokes, and access personal data without your knowledge. 2.
