Why? There is usually no sound technical reason - other than a
physical hard drive failure - for reinstalling WinXP repeatedly. (And
certainly not for the two reasons you've mentioned.) When properly
maintained, even a Win3.x or Win9x installation could be made to last for
years. And WinXP is much more robust than they ever were. What specific
problems are you experiencing that are causing such a drastic action?
Wouldn't it be easier, in the long run, to just fix those, rather than
repeated reinstalling the OS?
The error message you received is somewhat misleading. What it really
means is that you've activated "via the Internet too many times within the
last 120 days." Because there is no sound technical reason for
reinstalling and re-activating WinXP so frequently, the automatic
presumption is that the OS is being installed on multiple machines. I
really think Microsoft should fix this message, but it is, in reality, a
relatively minor "cosmetic" issue, so they're probably giving more weight
to some cost-benefit analysis more than they are the occasional customer's
confusion.
There's no limit to the number of times you can reinstall and activate
the same WinXP license (retail or OEM) on the same PC. Nor is there ever
a charge. Nor does a Product Key (so long as it's not an evaluation
license) ever expire. If it's been more than 120 days since you last
activated that specific Product Key, you'll most likely be able to
activate via the Internet without problem. If it's been less, you might
have to make a 5 minute phone call.
