Question ? What is best way for revenge of Windows Helpdesk ( scammers from India )

[3]

Hello,
Today i got again a phonecall from a Windows Helpdesk scam firm with a typical indian accent. Last year
those firms phoned me already a few times and i played a bit with them acting the stupid one and just wasting
their time. I watched a few videos on youtube and found a few ones where people locked the computer of the scammers.
What would be the best and easiest way to realy f..k up their system ?
Or have you got any other good ideas what i could do to realy nerve them.
I would set up a virtual computer windows 7 or 10 with a few basic programs on.
Would it be possible to rat them over a Remote Desktop Software ?
Would be nice to hear of some ideas you could think of.

Try to delete all their files

A slow burn - Use scheduled tasks to add/remove random bytes to files or delete/overwrite random registry entries. You can use PowerShell and really add whatever logic you want into the script. To avoid detection, piggyback it onto an existing scheduled task...like chrome updates or windows updates.  Their system will just get more and more corrupt over time.
