So what should I do? Install an x86 bit version and have Windows updates
or keep my PC without updates?
Do not skip the updates unless you never connect the PC to a network (even only a local network where other computers may get a virus) and you never use removable media.
Rather locate the source of the problem. Why does your computer freeze.
- Any errors in the event log?
- Did you try deleting the SoftwareDistribution folder?
net stop wuauserv, then delete the folder and do a
net start wuauserv).
- Does this happen after a clean reinstallation before you reinstall any non-OS software? (e.g. third party software which may cause the problem.
- Did you scan for virusses? Is your DNS working and are there no entries for windowsupdates in your
hosts file? Did you try to boot a liveCD and scan the system?
- etc etc.
As for the OS choice: 32 bit software is ancient. Try to use it only on machines which only have a 32 bit CPU or with 512MiB or less memory. (I know it is theoritically 4 GiB, but you want to have virtual address space for mapping, random address allocation, PCI devices, nmap files etc. All of this can not be used where there is already RAM occupying that address space. Which mean filling all of the normal 32 bit address space with mapped memory is a bad idea.)
