On the internet we found 2 files that can be replaced on Windows 7 clients to boot them faster. Learn how to do that here.

Before doing the following steps, we recommend making a back of your current image. The file replacement is better done in fresh image with just drivers installed.

1. Download the from our site and keep in desktop or any other location, for now we have it on desktop (Figure 1).

2. Extract it on desktop, it will have two files "bootmgr" and "winload.exe" (Figure 2).

Note: the "bootmgr" file is hidden, so you need to show hidden system files to see the "bootmgr" file after extracted.
