Auto-boost active apps, clear background bloat, and get peak performance in real time—reverting instantly when you switch away.
~20 MB self-contained·
No .NET runtime required·🔒 Dry-run mode includedEvery layer between your hardware and your frame rate — tuned, debloated, and fully reversible.
Detects the active foreground app, automatically raises its CPU priority, and instantly reverts when focus shifts.
Real-timeAutomatically switches Windows power plans with smart debouncing so quick Alt-Tabs don't cause thrashing.
AutomaticCategorized, one-click toggles: disable auto-driver updates, notifications, Store auto-updates & more. All reversible.
40+ tweaksRemove bundled Windows apps and junk files — temp files, shader cache, update backups & registry leftovers.
Reclaim spacePre-tagged service groups: Unwanted, Telemetry, Gaming, and Background. Stop what you don't need.
Smart groupsPeriodically clears standby memory lists, stops memory leaks, and optimizes page files to eliminate micro-stutters.
Memory boostVyrex fingerprints your CPU, GPU, RAM timing and storage. Compares current Windows settings against what your hardware actually supports. Takes under two minutes.
A plain-language list of proposed tweaks — each with the registry path, current value, and expected effect. Accept all or pick line by line. Nothing happens without your explicit approval.
Changes land immediately. A backup snapshot saves automatically so reverting is one click — no system restore needed. Audit log tracks every modification with timestamps.
"Picked up roughly 40 frames in the games I actually play, on a three-year-old build. The review screen before applying is what sold me — I could see every registry change."
"Render exports got noticeably faster once background indexing was cut back. The Debloater cleared 4GB of junk I didn't know existed. Not just gaming — it's for anyone running real workloads."
"Reverted one setting that conflicted with my capture software using the snapshot rollback — took ten seconds, no restart. The audit log showed me exactly what changed. That earns trust."
In most cases, yes — particularly by reducing background load, auto-boosting CPU priority for your active app, and stabilising frame times. The gain depends on how much headroom your hardware had left unused by default Windows settings.
Vyrex shows every proposed change before applying it and saves an automatic backup snapshot first. A blocklist of 18+ protected system processes (csrss, lsass, dwm, svchost) ensures critical processes are never touched. Dry-run mode lets you simulate everything with zero real changes.
Under normal use, no. The vast majority of changes are registry and power settings that are fully reversible with one-click rollback. Irreversible actions are clearly labelled before you confirm. The audit log tracks every modification.
It uses Win32 SetWinEventHook to detect your active foreground app, then raises its CPU priority through the levels (Idle → BelowNormal → Normal → AboveNormal → High). When you switch away, it instantly reverts. Power plans are debounced to prevent thrashing during quick Alt-Tabs.
No. Guided mode applies a matching profile automatically based on how you use your PC. Expert mode is there if you want to choose every row yourself and see the registry paths.
No. Vyrex is built as a single self-contained ~20MB .exe via Native AOT. No .NET runtime install required. Data is stored under %APPDATA%\Vyrex\ — config, profiles, and daily audit logs.
Occasionally — any tool that edits registry settings can trigger heuristic false positives. Downloading only from the official site and adding an exclusion resolves this. The tool is built with Avalonia UI and .NET 8 Native AOT.
Nothing changes until you say so. The scan takes under two minutes.
Single self-contained .exe — no install wizard, no runtime dependencies.
