Windows7 optimizes two

one, removes 32-bit Windows
7 4G memory limit

Microsoft official has instructions on different versions of Windows memory limit (link), 32 of which Windows 7 also supports up to 4G of memory (links). This is undoubtedly a big regret for the current memory cabbage price, 4G and above memory is very common. It’s like a manpower, but it’s not good. But we all know that 32-bit Linux can use more than 4G of memory through PAE (Physical Address Extension) technology. Is Windows 7 also possible? The answer is yes (link), it seems that Russian hackers have provided a crack (thanks to the great Russian state and government), and you can find a lot of results on the Internet with "ReadyFor4GB Windows 7&Prime" as a keyword. After applying this patch, you can use more than 4G of memory, and it is completely feasible to try it by myself. This very NB patch says that you can use up to 128G of memory, and I have no conditional test to be true. The following is a screenshot of the machine after patching:

The download link for the patch is given here, right-click AddBootMenu.cmd after decompression, and then “run as administrator", end It will be fine to restart later.

Second, allowing multiple users to use the same Windows 7 machine at the same time

*nix The system has always been multi-user multi-tasking operating system
, While Windows is also known as multi-user multitasking, it has not been able to allow multiple users to log in while using the same machine. This limitation has also been broken (link). From the previously linked article, this crack was first proposed by a hacker named sunmorgus in a forum on thegreenbutton.com forum for Windows Vista. This crack is a Windows 7 system that allows users to remotely log in to the machine using RDP on other machines without causing the user who is logged in to be forced to log out. In this way, the same Windows 7 machine can also achieve true multi-user multitasking!

The download link for this patch is also given here. Right-click install.cmd after decompressing, then “run as administrator", wait patiently for a few minutes until the end, then restart the machine should be able to It is.
