| + | **Not all developers are created equal. I had a meeting to do an induction with a new developer. He had not received his machine yet, courier issue, so I proceeded to help him set up his Windows laptop. Just so that he could get his email so long and communicate with his team etc. He had an issue setting up openvpn, so I asked him to share his screen so I could help him. I suddenly had flashbacks of Windows XP computers with icons and folders littering the desktop, all with the single purpose of pirating something. Folders like fix to download spiderman or whatever. Since the machine was also as slow as treacle running uphill, I suggested he do some virus scans.(Installing malwarebytes took 40 minutes!) In the end I continued helping him at a snail’s pace with everything freezing so often. To make matters worse, he would unplug the laptop power between every call, making the laptop even slower. After the roller coaster ride was over I asked him the specs of his machine. He blamed the i3 CPU for the slowness. Though it could be, the fact that the laptop had only 2Gb of memory was what caught my eye. Windows 10 alone may be fine, but running office as well as your frikking huge IDE and 3 different browsers with many open tabs... and you wonder why it freezes? Needless to say I had a good chuckle over a hot cuppa. ** | ||

| A: My first stop would be the UEFI BIOS, and make sure it does not boot to windows under the boot section. I looked at the answer and the XPS BIOS does not look like that. Tap F2 to enter the BIOS and you should see a block marked boot. My money is on the first entry being windows boot manager or something similar. | A: My first stop would be the UEFI BIOS, and make sure it does not boot to windows under the boot section.
