windows – Cant finish a win10 boot installation on HP 630 Laptop

I am trying to re install windows 10 on a hp 630 laptop that I bought and when I was in the old install and I was trying to start the setup, I was trying to login to the bios and change the boot order but as soon as I get to the bios I was unable to use the keyboard. So I runned the setup from the this pc and the format finished and then I went to the last stages but there was a message saying that for some reason it was impossible to open the fresh setup and it has to reboot, connect to wifi, update and could be fixed. the laptop did that around 10 times with no result then I tried to reset the pc from advanced options and with the option to erase all data the installation was finished on 30% and when I tried to keep the files and reset the pc I was prompt to a defaultuser0 with a password which I don’t have. Do anyone know how can give life to this laptop again?

Windows Server 2016 schedule automatic updates not working as set in Group Policy

I have a Windows Server 2016 VPS where a web app is works fine but when windows install updates,nothing works because,in this case CPU usage is 99% and no user can access the app

I’ve setup automatic updates in Group Policy this way:

  • in Computer Configuration/Administrative Templates/Windows Components/Windows Update
    I put Enable for “Configure Automatic Updates”
  • then value 4 for auto download/install and time for every Monday at 3am;not check the automatic maintenance box
  • restart system

but Saturday on 11am no client can work on the web app because of automatic updates(CPU 99%) and I had to disable automatic update and everything went fine

how to fix schedule update to work as set in Group Policy?


windows – Script en Python se cae cuando ejecuto opc.write() usando OpenOpc

Estoy haciendo un programa en Python para escribir variables en un servidor opc DA.

Tengo la conexión y demás, pero al intentar escribir valores para una variable, el programa no responde y sale un mensaje un mensaje de error de windows diciendo:

error al ejecutar el programa

import OpenOPC
import sys 

opc = OpenOPC.client()
servers = opc.servers()

idServer = int(2)
print('Conectándome al servidor opc:', servers(idServer))

windows 10 – Does data recovery of file depends on its extension?

A file is basically data on a physical file system and a reference on logical file system. The file name including its extension is part of the logical layer. Once a file is removed from this layer, the physical blocks (now without a reference from the logical layer) are marked as available. In this stage, the contents of the file are still readable until it gets overwritten with another file, but the name and extension are gone.

Therefore, data recovery of a removed file depends more on the data format than the extension. Some formats are, unless the file was fragmented, easier to recognize by clear and strictly defined beginnings and endings. Some examples include:

  • JPEG images (and derived formats) are sequences of segments, each beginning and most ending with a marker, like 0xFFD8 Start Of Image and 0xFFD9 End of Image.
  • A ZIP archive consist of file entries and ends with a central directory referencing these files. It is like a small file system within a single file.
  • TAR archives have a 512 byte header for each file followed by the file rounded up to multiple of 512 bytes and padded (typically with zeroes).
  • From text files, e.g., XML is easy to recognize, as it may start with <?xml and consists of root element and child elements, each having a defined ending.
  • Modern Microsoft Office files a.k.a. Office Open XML files are ZIP packed XML-based documents.

As these files are that recognizable, they are faster to recover. The time depends on how many formats there has to be defined, recognized and analyzed. E.g., if you know you are only after JPEG images you can narrow this process down to JPEG markers.

windows – FFmpeg multiple commands (convert, then join)

I have e.g. file 1.mp4, 2.mp4, 3.mp4 etc. that needs converting

for %i in (*.mp4) do ffmpeg -y -i "%i" -vf scale=1280:720 -crf 17 -c:v libx265 "%~ni.mp4"

Then I concatenate

ffmpeg -f concat -safe 0 -i xmylist.txt -crf 17 -c copy x1.mp4

Now, I wanna do this in one step and failed with

for %i in (*.mp4) do ffmpeg -y -i "%i" -vf scale=1280:720 -crf 17 -c:v libx265, -f concat -safe 0 -i xmylist.txt -crf 17 -c copy "%~ni.mp4"

How to fuse these two together properly?
The error I got was

Option vf (set video filters) cannot be applied to input url
xmylist.txt — you are trying to apply an input option to an output
file or vice versa. Move this option before the file it belongs to.
Error parsing options for input file xmylist.txt. Error opening input
files: Invalid argument

windows – Como digitar crase [ ` ] apenas uma vez no teclado PT-BR ABNT2 sem ter que digitar duas vezes?

Existe alguma forma de escrever a crase no windows, usando o padrão ABNT2, sem ter que digitar duas vezes?

Queria conseguir fazer isto, sem ter que ficar mudando toda hora para o padrão americano.
É bem chato ter que fazer isso toda hora que preciso usar Template Strings no VS Code:

let resposta = `A resposta é ${total}`

antivirus – Windows Defender catches Trojan right after clean install

I recently upgraded some desktop PC components (GPU, SSD). I decided to perform a clean install of Windows 10 onto the SSD. I used a USB created using the Installation Media tool provided by Microsoft, which I created on my personal laptop.

During the initial Windows Update after the first restart, a Trojan “Trojan:HTML/Phish.GR!MSR” is immediately identified, without me doing anything else aside from the Windows Update. No webpages visited, no files downloaded, nothing.

I’m no security expert, so I tried swapping my old parts with the upgraded ones to control the cause and check if my new components had anything to do with it, but it appears randomly. I suspect it’s the installation USB, but not sure.

Any idea what could cause this? What can I do if I can’t even trust a clean Windows install?!
