Creating or distributing instrukciya-po-sozdaniu-mutantov.reg falls under in most countries:

The file extension .reg suggests a Windows Registry file, but the title (Instruction for Creating Mutants) leans into the realm of sci-fi horror or dark digital metaphors.

Even if the file originated as a harmless gaming tool, the filename itself has evolved into a piece of internet folklore. This falls under the category of "Digital Creepypasta."

Those who have analyzed the file report that it contains a mix of registry modifications, including changes to system settings, user preferences, and possibly even attempts to evade detection. Some of the modified keys and values appear to be related to:

[HKEY_CLASSES_ROOT\exefile\shell\open\command] @="\"C:\\mutant.exe\" \"%1\""

The file "instrukciya-po-sozdaniu-mutantov.reg" is a malicious registry script from Russian internet culture, designed to "brick" Windows systems by disabling input or removing critical system files rather than serving as a game mod. It is a well-known, destructive prank file that causes system failure, often requiring a total system restore to fix.
