Installing operating systems from USB flash drives or memory cards is increasingly common, for example on small laptops without DVD drives.
Here is an easy way to install Windows from USB using WINDOWS 7 USB/DVD DOWNLOAD TOOL
TRIM support for SSDs
SSDs introduced fast reads and writes compared with HDDs, but quickly showed considerable performance degradation after short use. Existing operating systems did not work correctly with SSD controllers: instead of writing zeroes to empty blocks, they marked whole blocks as deleted. Because SSDs write blocks of a fixed size, this meant reading the area again, modifying it (writing zeroes), then writing the data.
PSR – Problem Steps Recorder
Windows 7 includes Problem Steps Recorder, launched by typing psr in Start. It captures the desktop and all actions performed, helping troubleshoot users' PCs when they cannot describe the problem and remote access is unavailable.
Disabling hibernation and deleting hiberfil.sys to free disk space
Windows 7 enables hibernation automatically after installation, saving memory contents to hiberfil.sys on shutdown. This speeds startup significantly: instead of loading applications individually, the contents of hiberfil.sys are restored to memory.
Windows Automated Installation Kit (AIK) for Windows 7
Windows® Automated Installation Kit (Windows AIK) is a set of tools and documentation supporting Windows® configuration and deployment.
Playing subtitles in Windows 7 using DirectVobSub
Although Windows 7 and its default Media Player 12 now support most formats and codecs (Xvid, DivX, H265), they still cannot display subtitles supplied as an external file, usually .srt, rather than embedded in the video.
Windows XP/Vista/7 as a network router
A workstation running Windows 7/Vista/XP can also act as a network router, useful for quickly connecting networks with different address ranges when a professional router is unavailable. In this example, a Windows XP workstation connects network A (10.10.10.0/24) with network B (192.168.20.0/24) while providing Internet access to both.
