This value has a long name, but you won’t regret modifying it if you have a big Internet connection (10 Mbps and up) and often upload stuff. This value represents how much data can be sent from your computer without receiving an acknowledgement (ACK) packet.

Every time you send small chunks of data on the Internet, your computer has to wait for this packet, which tells your end of the network, “Everything’s OK! Send more!” Sometimes, due to latency and poor peering, this might not be ideal. So, you can edit this value to allow more data to be sent without waiting for that packet to come.

Time to Live (TTL) tells routers how long a packet should stay in the air while attempting delivery before giving up and discarding the packet. When the value is often high, your computer spends more time waiting for a failed packet to deliver, effectively decreasing the amount of productivity in your network.

Without a value set, Windows waits 128 seconds for the transaction to finish. This makes your computer lag terribly if you’re in the middle of something and your connection with a server unexpectedly goes south.

IRPStackSize (I/O Request Packet Stack Size) represents how many 36-byte receive buffers your computer can use simultaneously. It allows your computer to receive more data at the same time. Your system usually allocates 15 IRPs in its network stack. More often than not, you’d benefit much more with 32, although you can configure up to 50. Try 32 first.

Pagefile.sys acts as a virtual RAM, which Windows uses as RAM to store programs that are not in use, thus putting less pressure on the actual RAM. The page file size is usually near the size of your actual RAM, so it can take up a lot of space depending on your RAM. If you set the pagefile to delete with shutdown, you will save some hard drive space in exchange for slightly prolonging your shutdown time.

Here is one way you can get the system to automatically delete the pagefile.sys on shutdown in Windows 10.

By default, Windows 10 has a 10-second delay during boot before all your apps and programs become accessible. This is called the “Startup Delay,” and it helps make sure everything works as it should when you start up your PC. If, however, you have a powerful PC, or not many startup programs in Windows 10, then you can try to reduce or even disable the startup delay altogether to help your PC start up faster.

If you’ve used Windows for any length of time, you’ve likely tried to open a file with an unknown extension. When you double-click on a file with an unknown extension, Windows presents you with this irritating dialog:

If you selected “Select a program from a list of installed programs”, you would get this much more useful dialog instead:

The registry hack will show you the second Open With dialog instead of that irritating first one.

Windows 10, by default, sends everything you search for in the Start Menu to their servers to give you results from Bing search.
