I started working for Microsoft!

I’m very happy to announce today was my first day of working at Microsoft!

While the job is fully remote, I chose to work onsite, at the Lisbon Office of Microsoft Portugal, for my first day.

I’ve met some of my colleagues, and thankfully I liked the vibe of the workplace, with several people helping out.

I also liked the space, modern, yet comfortable and cozy.

As for the actual job, I will be working with Microsoft Defender for Endpoint.

Let us hope this is the beginning of a long and productive journey!

I made a tool to fix the CrowdStrike incident!

I just released a tool to fix the problems with the recent CrowdStrike update.

This helps delete the problematic files, and is made simple to use, so it can be used for Junior IT personnel.

This is made in Object Pascal, with Lazarus IDE, and I’m releasing it for free, as open-source.

Features

  • Simple and intuitive
  • Ability to first check for the problematic files (C-00000291*.sys), without changing anything on the system
  • 1-Click removal of the problematic files
  • Ability to Enable and Disable the Windows Safe Mode – both from the App and from the WinPE bootable ISO
  • Does not require the use of command line
  • Works fully offline and does not contact any servers (eg. does not “phone home”)
  • Free and open-source

How to use

1. Boot into Safe mode or Windows Recovery Environment
2. Run the application and click "FIX IT"
3. Reboot
