This hurts. I still remember when I rendered our first family PC unbootable. It was a Pentium II 266 with a tiny 3GB HDD running Windows 98, and apparently some sub folder of system32 seemed a good place to start doing some clean up to win back some extra space.
Turns out, it wasn’t.
Now turns have tabled and I’m the stereotypical IT professional who helps out fixing PCs/smartphones
