I'm doing a favour for a friend by tidying up his office PCs by clearing out the bloat of software and files. The trouble is it's been a good 5 years plus since I did Windows admin in anger, and even then it was for Win2K rather than home.
Any advice for what I should be doing with this shitty heap of junk? I'm fine with clearing out all of the crud, my main questions are around what the best and cheapest ways of getting the OSes up to date are.
The scrap heap comprises:
Win 8.1 i5 2.8 GHz 4GB Desktop
This is my friend's main computer, and most powerful of the bunch. This is the only one which he definitely needs to keep in the short term, and the others can probably all go to the bin if they can't easily be updated.
This thing has a 1TB hard drive split 150/850 between a C and a data disk, but all of his User/.. folders are on the C drive and it's just rammed. I don't think I'll have much success in telling him to make sure he saves to D rather than C...anything I should be aware of before making things like his Documents folder just point to the D drive so he doesn't have to think about it?
Win XP (!!!!!!!) HP Centrino Duo (!!!!!!) ?GHz ?GB Laptop
Asides from knowing that XP definitely needs to go, I don´t know what´s best for this thing. His partner uses this laptop for watching and is a technophobe, so I don't think a Linux thumbdrive type setup would work unfortunately.
Win 7 Pentium? ?GHz ?GB Laptop
This looks to be about ten years old. I have nothing else to add.
Are there free Windows upgrades that would suit any or all of these things, or should I look for cracked versions?
Besides going through Control Panel and startup programs, any tips for clearing out bloatware and other crud?
What's the view on anti-virus for Windows home setups these days? My friend has some subscription to AVG that he is VERY wedded to, but my suspicion is that it's a big load of snakeoil, and it pesters the fuck out of everything. There will be a more suitable and free approach out there, right? Right?!
