A Windows recovery USB may boot another compatible PC into recovery tools, but it should not be treated as a universal system image or manufacturer recovery drive.
A Windows recovery drive can provide Windows Recovery Environment and, if you chose to include system files, options to reinstall Windows. It does not contain your personal files. OEM recovery media may be tied to a model and may include device-specific drivers or factory software.
A vendor's factory recovery USB may reinstall the wrong drivers or refuse another model. A generic Windows recovery environment may still boot but cannot transfer licenses or repair hardware failures. For a failed disk, first preserve data and then replace the disk.
Start the target PC without the USB, check drivers and activation, then verify personal files. Keep a fresh recovery drive made on that PC if you expect to use it again.
Will it copy Windows from the first PC? No. A recovery drive is not a clone of the first PC.
Can I use it on a different brand? The basic recovery environment may work, but OEM restore content and drivers may not.
A Windows recovery USB may help another compatible PC, but it cannot replace that PC's own backup or guarantee a model-specific factory restore.
