SRUM Parser

Parse Windows SRUDB.dat in your browser. Nothing is uploaded.

Frequently asked questions

What is SRUDB.dat?
SRUDB.dat is the database file used by the Windows System Resource Usage Monitor (SRUM). It records per-application CPU cycles, foreground/background time, network bytes, and energy use, with roughly 30–60 days of history.
Is my file uploaded to a server?
No. Parsing happens entirely in your browser via WebAssembly. The file you drop never leaves your device — there is no upload endpoint.
Where do I find SRUDB.dat on a Windows machine?
It lives at C:\Windows\System32\sru\SRUDB.dat. The SRUM service holds an open handle on a running system, so most analysts copy it from a forensic image or a volume snapshot.
Does the parser need an internet connection after loading?
No. Once the page and the WASM module are cached, parsing works fully offline.
What browsers are supported?
Any modern browser with WebAssembly support — Chrome, Edge, Firefox, Safari, and Brave on desktop. Tested primarily on the latest Chromium.
