Windows 10 users seek enhancements in security, stability, performance, integration, and customization, while desiring lighter hardware and efficient updates.
If real-time customized port scanning can be added, for example, instead of a default port such as 8080 or 443, if we can use a customized port such as 9876, that capability would be great.
Senior Technical Manager at a tech vendor with 10,001+ employees
I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
If there were video courses attached to how to safely use it, especially for absolute beginners with no previous experience using Linux operating systems, I think that could be very useful.
Cloud Ops Lead at a tech vendor with 10,001+ employees
Microsoft can improve their Teams product because everybody uses Teams, and it's very clunky and unfriendly in terms of scrolling back, downloading files, and moving back and forth within the different teams.

Investment in Windows 10 may not be ideal as the world is changing with advancing technology in the AI age.

Featured Reviews

Ciyagi Ciyagi - PeerSpot reviewer
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
R Pranavan - PeerSpot reviewer
Software Engineer at a tech vendor with 201-500 employees
Collaborative development has become more secure and efficient for our team
We have faced some issues with Windows OneDrive because if one developer has a folder in a common OneDrive folder, it took some time to show it to others. It becomes somewhat difficult to work, as there is latency on that, so if you update that, it will be more efficient and useful for the developers. My main focus on Windows 10 is the giving of regular updates, so it might take some time to update Windows, which is also mandatory. As a developer, when we are working with Windows 10, if it takes more time to update and restart the PC, it affects our efficiency at work. If we could stop the updates on a regular basis or if they were delivered faster, it would be easier. As a developer, the frequent updates are too annoying for working on it, so it would be better if we stop the frequent updates and only provide the most important ones. Performance issues over time due to background apps and programs piling up and using an SSD instead of a hard disk are also concerns.
