Drop source-routed packets
Discards packets that dictate their own route (a spoofing vector) instead of forwarding them.
Game NetworkEvery setting HKTweaks can change: what it does, how risky it is, whether it needs a restart and which rank unlocks it. The free app lists the locked ones too.
Discards packets that dictate their own route (a spoofing vector) instead of forwarding them.
Game NetworkTriggers loss recovery after 2 duplicate ACKs instead of 3 — a lost packet is resent one round trip sooner.
Game NetworkRefuses routing changes suggested by other hosts — protects against route hijacking and stops odd path changes mid-session.
Game NetworkKeeps MTU discovery enabled (right-sized packets, no fragmentation) and disables the slow black-hole fallback that can shrink packets after a few losses.
Game NetworkMakes sure SACK is enabled, so only the lost segments are resent after packet loss (the default on modern Windows — this pins it).
Game NetworkSets "Do not use NLA" so QoS policies (DSCP marking, used by Discord/Teams and router gaming QoS) apply on non-domain networks too.
Game NetworkRaises the neighbour-cache limit from 256 to 4096 entries — no re-resolution stalls on large LANs / LAN parties.
Game NetworkSets the maximum simultaneous TCP connections to the ceiling (16,777,214) — the default is already high; this makes sure heavy P2P/game-server browsing never hits a limit.
Game NetworkRaises the free-TCB pool and hash table for a busy connection table (launchers + game + voice + browser all at once).
Game NetworkLets the network card write packet data straight into the CPU cache (needs card + chipset support; ignored otherwise).
Game NetworkTurns off the automatic IPv6-over-IPv4 tunnel adapters (6to4, ISATAP) — fewer virtual interfaces and no odd NAT/route behaviour for game traffic (Teredo is a separate v1 tweak).
Game NetworkStops Windows switching to a backup gateway on a short hiccup — avoids mid-match route flapping on single-router home networks.⚠ Failover to a backup router/gateway no longer happens automatically.
Game NetworkStops the PC joining multicast groups (IGMP) — less background chatter on the LAN; games do not use multicast.⚠ IPTV, multicast streams and some LAN discovery stop working.
Game NetworkA failed TCP connect gives up after 2 retransmissions instead of retrying for many seconds — servers that are down fail fast and the client can pick another.⚠ On a weak Wi-Fi/mobile link connections fail sooner instead of retrying.
Game NetworkDisableDHCPMediaSense: a cable wiggle or Wi-Fi blip no longer tears down the IP configuration and every open connection.⚠ After a real network change the PC may keep a stale IP address until you reconnect.
Game NetworkRaises Winsock's default send/receive buffer from 8 KB to 64 KB — fewer dropped datagrams on bursty voice/game traffic.
Game NetworkLowers the first TCP retransmission timer from 3000 ms to 2000 ms — a lost SYN or first packet is resent a second sooner.⚠ On a slow or unstable link this triggers needless retransmissions.
Game NetworkRaises the datagram-size thresholds below which Windows fast-paths UDP packets. TCP is not affected.
Game NetworkRaises the pool of outbound UDP ports from ~16,000 to ~55,000 — helps with many simultaneous game/voice sockets. Revert restores the Windows default (49152 / 16384).
Game NetworkLets non-blocking sockets queue small sends in the AFD buffer instead of stalling — smoother throughput for games that use overlapped I/O.
Game NetworkMakes Winsock complete receives as data arrives instead of waiting for the sender's PUSH flag — lowers delay for chatty TCP game/voice protocols.
Game NetworkEnables window scaling without timestamps (Tcp1323Opts) for better throughput and latency.
LatencyTurns off Explicit Congestion Notification, which can add latency on some routes.
LatencyRemoves TCP timestamp overhead on every packet for slightly lower latency.
LatencySets a clean default TTL of 64 hops (standard for gaming setups).
LatencyRemoves any "useplatformclock" boot override so Windows keeps using the CPU's TSC — the low-latency timer. No-op when it was never forced. Restart required.
LatencyStops the network card from batching outgoing packets into larger chunks before sending — trades a little throughput for steadier, lower latency.⚠ Higher CPU load during heavy uploads on some network cards.
LatencyTurns off legacy NetBIOS name resolution on all adapters (less broadcast noise, more secure).⚠ Breaks name resolution for old LAN shares and some LAN games.
LatencyStops the network card from batching packets before interrupting the CPU — lower latency/jitter in fast-paced games.⚠ Higher CPU load during heavy downloads on some network cards.
LatencyStops Windows from powering down your network card to save energy (avoids latency spikes).⚠ Slightly more power draw; Wake-on-LAN behaviour can change.
LatencyDisables Receive Segment Coalescing so packets aren't batched — lower latency, may lower bulk throughput.⚠ Higher CPU load during heavy downloads on some network cards.
LatencyLowers the retransmission count so dead connections drop faster.⚠ On a weak Wi-Fi/mobile link this can cause more dropped connections instead of fewer.
LatencyKeeps every PCIe link (GPU, NVMe, NIC) at full power so none has to wake up and re-train mid-game.⚠ More heat and power draw (laptops: shorter battery life).
LatencyCoalescingTimerInterval=0: Windows stops batching timer wake-ups, so timers fire when they are due rather than in a group — more precise, slightly less idle savings.⚠ Slightly more idle power draw (laptops: a bit less battery life).
LatencyRaises the Pro Audio multimedia scheduler class (priority 6, high scheduling & I/O priority) — fewer audio crackles/latency spikes in DAWs, voice chat and low-latency audio drivers.
LatencyLowers the load threshold that triggers a higher performance state from 60 % to 10 % — the CPU speeds up at the first sign of work instead of after a delay.⚠ More heat, fan noise and power draw (laptops: shorter battery life).
LatencyStops Windows connecting to suggested public Wi-Fi hotspots on its own.
NetworkStops Windows from using your upload bandwidth to share update files with other PCs on the internet — frees bandwidth for gaming.
NetworkRemoves the network packet limit imposed by multimedia (index → disabled).
NetworkFrees the 20% of bandwidth reserved by default for the QoS Packet Scheduler.
NetworkBigger hash table and higher TTL ceilings for the Windows DNS cache — fewer repeated lookups for launchers and CDNs.
NetworkRaises the WinInet limit to 10 parallel connections per host (default 6 in many apps) — faster page/asset loading in Windows-based launchers.
NetworkWindows 11: upgrades DNS to encrypted DoH automatically whenever the resolver supports it (Cloudflare, Google, Quad9, AdGuard).
NetworkStops Windows retrying failed names with parent-domain suffixes — failed lookups return immediately.
NetworkRemoves the legacy NetBIOS LMHOSTS name-file lookup.
NetworkWindows stops racing every adapter's DNS servers and the parallel A/AAAA lookups — one clean, predictable query per name.
NetworkRaises IRPStackSize to 32 so a PC sharing folders never returns "not enough server storage" under heavy transfers.
NetworkLets file copies to a NAS / other PC use the full link and large packets.
NetworkReduces latency by disabling TCP aggregation on all interfaces.⚠ Network tuning: the benefit depends on the game and connection; it can slightly reduce throughput on some setups.
NetworkTurns off the Teredo IPv6 tunneling protocol.⚠ Can break the Xbox network test / NAT type and some peer-to-peer games.
NetworkIncreases the number of ephemeral ports and lowers TIME_WAIT (better under load).⚠ Network tuning: only useful with a very large number of simultaneous connections.
NetworkSets DNS to 1.1.1.1 / 1.0.0.1 on all active network adapters.⚠ Changes your DNS: ISP/parental filters and some company/VPN name lookups stop working; speed varies by location.
NetworkSets DNS to 8.8.8.8 / 8.8.4.4 on all active network adapters.⚠ Changes your DNS: ISP/parental filters and some company/VPN name lookups stop working; speed varies by location.
NetworkEnables RSS, normal autotuning and disables heuristics for more stable throughput.⚠ Network tuning: the benefit depends on the connection and can be zero or slightly negative.
NetworkStops the resolver sending mDNS queries for .local names — less LAN broadcast noise (LLMNR is a separate v1 tweak).⚠ Chromecast, AirPlay, network printers and some LAN devices may no longer be discovered.
NetworkStops apps probing for a "wpad" proxy on every connection — a classic cause of slow first requests and a MITM vector.⚠ Company / school networks that rely on automatic proxy discovery (WPAD) stop working.
NetworkStops the WPAD service that hunts for proxy scripts — apps that use WinHTTP connect directly.⚠ Company / school networks that rely on automatic proxy discovery stop working.
NetworkKeeps IPv6 available but tries IPv4 first — avoids slow fallbacks when your ISP's IPv6 route is worse than IPv4 (different from fully disabling IPv6).
NetworkSets DNS to 94.140.14.14 / 94.140.15.15 — resolves normally and blocks ad and tracker domains for the whole PC.⚠ Replaces your DNS and blocks ad/tracker domains for the whole PC — some sites, apps and free games may misbehave.
NetworkSets DNS to 9.9.9.9 / 149.112.112.112 on active adapters — fast, and blocks known malicious domains.⚠ Replaces your DNS: ISP/parental filters and some company/VPN name lookups stop working.
NetworkDisables IPv6 (can reduce latency on some setups). Restart required.⚠ Some apps, Xbox networking and a few game servers expect IPv6. Prefer "Prefer IPv4 over IPv6" instead.
NetworkTurns off Energy Efficient Ethernet / Green Ethernet / Gigabit Lite, which throttle the link when traffic is light.
Network CardIntel NICs stretch the gap between frames on a busy link — turning it off removes that adaptive delay.
Network CardThe card stops answering ARP and IPv6 neighbour requests on behalf of a sleeping PC — one less firmware feature running in the datapath.
Network CardStops Windows periodically pinging Microsoft servers to decide the "internet access" status of the network icon.
Network CardRemoves IPsec offload firmware from the datapath (only used with VPN/IPsec tunnels, which software handles fine).
Network CardForces the standard 1514-byte frame size — jumbo frames add latency for small, frequent game/voice packets.
Network CardIP/TCP checksums computed by the card in both directions (the default; this repairs a driver left in a slow software mode).
Network CardTurns on the driver's own throughput-boost mode for Intel wireless cards.
Network CardUSB Ethernet/Wi-Fi dongles are no longer allowed to power down between packets.
Network CardSpreads incoming traffic across CPU cores at the driver level.
Network CardLets the network card compute UDP checksums instead of the CPU — less per-packet overhead under heavy game/voice traffic.
Network CardRemoves the LLTD mapper/responder bindings (they answer the "Network map" feature and nothing else) from every adapter.
Network CardRemoves the priority/VLAN tag from outgoing frames — a few bytes less per packet; only matters if your switch does not use VLANs.⚠ Breaks networks that use VLANs or QoS tagging (some offices, ISP boxes with IPTV).
Network CardStops the card from pausing traffic under load — trades a little reliability on saturated links for lower latency.
Network CardTurns off the legacy LSOv1 (v2 is a v1 tweak) so the CPU builds packets itself — steadier latency on small game packets.
Network CardStops the driver merging received packets before handing them up — each packet arrives immediately (complements the Windows-side RSC tweak).
Network CardRealtek / Intel "Shutdown Wake-On-LAN" and link-speed-on-shutdown switches off.⚠ You will no longer be able to wake this PC from shutdown over the network.
Network CardStops the card waking the PC and keeps the NIC out of its low-power listen state. Only turn off if you never wake this PC over the network.⚠ You will no longer be able to wake this PC over the network.
Network CardWindows stops pushing the PC name/IP to the DNS server at every connection — a small delay off each network change on home networks.⚠ PCs on a company domain or with local name lookups may no longer be reachable by name.

Display & GameSets the global Graphics Settings string: "Optimizations for windowed games" (flip-model upgrade), "Variable refresh rate" and the high-performance GPU as default on laptops with two GPUs.⚠ VRR optimisation can cause flicker on some FreeSync/G-Sync monitors — turn it off if the picture flashes.
Display & GameStops DWM rendering live window previews when hovering the taskbar or Show-desktop corner — less compositing work.⚠ Changes how Windows looks or behaves — you will notice it right away. Easy to turn back off.
Display & GameTurns off "Record what happened" (historical capture) — no rolling video buffer eating GPU/encoder time while you play.⚠ You lose the "record the last 30 seconds" background clips.
Display & GameTurns off the whole Win+G overlay framework (not just clip recording) — no overlay process hooking into games.⚠ Win+G, Xbox Game Bar capture and "record that" clips stop working.
Display & GameSets the "turn off display" timer to Never on AC power so a long cutscene, stream or download never blanks the screen. Revert restores 10 minutes.⚠ The screen never blanks while plugged in — risk of burn-in on OLED, and wasted power if you forget the PC on.
Display & GameStops the Store downloading app updates in the background while you play or stream.⚠ Microsoft Store apps and games no longer update themselves.
