A rescue USB ages in silence. The drivers go stale, the tools fall behind, and one day it cannot see a new laptop's SSD. Updating takes twenty minutes - if you protect your own additions first.
Both projects move fast. Sergei Strelec releases dated builds several times a year whose changelogs fix real field problems - recent notes mention WiFi connection fixes and BitLocker drive handling - while NHV Boot pushes frequent version jumps with refreshed driver packs. An old image is not a stable image; it is an image that has quietly lost support for new hardware. Here is the update routine that keeps your customisations safe.
Not cosmetics. New builds add storage and WiFi drivers for newer laptops, fix bugs the authors found in the PE itself, and refresh the bundled tools - imaging suites, recovery engines and browsers all move on. The day a client's brand-new laptop shows no disk in your old PE, the update you skipped becomes the whole story of the visit.
Before touching anything, copy off what is yours. On a Strelec USB that means the SSTR\USER area - especially your MY_DRIVERS packs - plus any portable tools you added. On NHV, note your customisations such as wallpaper changes, which live with the image. Updating the image itself never preserves these for you; your backup folder on the work PC is the only thing standing between an update and a lost driver collection.
If your images live on a Ventoy stick, updating is a file swap: download the new build from the official site, delete the old ISO from the data partition, copy the new ISO in. No formatting, no rebuild, and your other images stay untouched. This single convenience is why so many engineers keep Strelec and NHV on Ventoy instead of dedicated sticks.
For a maker's own boot USB, the honest method is to create it again from the new ISO with the author's instructions. That process formats the stick, which is exactly why the backup step comes first. After creation, copy your USER folder contents and added tools back, so the new build boots with your drivers and habits intact.
An untested rescue USB is a rumour. Boot the updated stick on your own machine, confirm the internal disk is visible, connect to WiFi once, and open one imaging tool. Two minutes of testing at your desk replaces an hour of improvisation at a client's office - and the full comparison video shows what a healthy, current build of each looks like when it boots.
Boot speed, tools, drivers and the final verdict - the complete Strelec vs NHV Boot comparison, step by step.
▶️ Watch Full VideoRegularly. Strelec publishes dated builds several times a year with program updates and fixes, and NHV Boot's version numbers climb quickly with refreshed software and driver packs. Checking both official sites every few months keeps a working engineer current.
Some builds mention updating bundled programs from within the PE when it has an internet connection, but the image itself - drivers, PE core, boot behaviour - only changes with a fresh download. Treat in-PE updates as a bonus, not your update strategy.
Mostly it will feel familiar - same menus, newer versions underneath. The visible differences are usually new hardware working that did not work before, which is the entire point of updating.
