Is there a free or very low-cost, and preferably not-too-complex way to set these PCs up with virtual or sandbox sessions so that whatever junk has accumulated during the day gets wiped out when the PCs are shut down or when users log off? Ideally this would also prevent virus damage to the PCs.
The PCs are all standalone, running Windows XP Home Edition SP3. They are older donated/recycled PCs, so they don't have a lot of processing horsepower. Typical setup is a P4 processor running around 2GHz, with 512MB to 1GB of memory, and disk capacity of 80 to 160GB.
Any suggestions welcome. Thanks.

Moved from XP to AV, Firewall, etc.
