Following ’s report that rnappp6.exe is burning CPU, and building on ’s hint to inspect the file plus ’s note about search noise, below is a focused, safe triage and removal plan that works on old and recent Windows installs.

Start by collecting evidence (don’t delete yet): find the on‑disk path, PID, parent process and file properties. On newer Task Manager you can right‑click → “Open file location”; alternatively run these from an elevated prompt to get PID and path:

tasklist /fi "imagename eq rnappp6.exe"
wmic process where "name='rnappp6.exe'" get ProcessId,ExecutablePath

Record the path, file size and the Properties > Details values (Company, Product, timestamps).

Analyze before acting: verify a digital signature if present, and compute a hash for lookup:

certutil -hashfile "C:\full\path\rnappp6.exe" SHA256

Search that hash on multiscanner services (or submit the file) rather than relying on filename Google hits — short/odd names often return unrelated pages (see ’s search). Use Process Explorer to view parent/threads, loaded modules and network activity; use Autoruns to find persistence points (Run keys, Scheduled Tasks, Startup folders).

Safe remediation sequence: isolate the PC from the network, make a copy of the suspect file for analysis, then stop the process (taskkill /pid <PID> /f) and remove startup/persistence entries. Reboot to Safe Mode if the file cannot be deleted. Run full scans with updated AV/antimalware (Windows Defender + a second opinion scanner). If the file proves signed by a legitimate vendor, reinstall/update that software instead of deleting. If compromise appears deep (new accounts, unknown services, data exfiltration), consider restoring from a known‑good backup or a clean OS reinstall.

This checklist avoids assumptions and prioritizes verifiable indicators (path, signature, hash, scanner results) so the true nature of rnappp6.exe can be determined reliably.

The fact that there is no information on it via Google is a good indication that it's probably not something you want on your computer. To find out more about it, go to the file itself (do a Search to find it), right-click on it, choose Properties, and get whatever info you can on it (Company, Version, date created, etc.)

A search for "rnapp6" gave 2 results, neither of which were conclusive (to say the least):
