Folks, my home network consists of 6 machines behind a
Microsoft ISA server firewall. Yesterday, a popup window
appeared apparently from Microsoft indicating that due to
a significant amount of hardware changes on my machine
(new drives etc which I recently added)that I needed to re
register the XP operating system and that I had three days
to do it.
Anyone familiar with this ?
That's WPA (Windows Product Activation) raising its ugly head. You
are lucky you weren't using the original XP (pre-SP1) as that doesn't
give you three days; the denial of service starts immediately.
There are three WPA models used for XP:
- no WPA (volume licenses)
- BIOS-locked WPA (big-name OEMs)
- per-component WPA (everyone else)
Per-component WPA monitors 10 items that are supposed to be
"hardware", and if "too many" of these changed, the assumption is made
that XP is running on a different computer.
In XP SP1, one of these items is weighted as 3 votes; the LAN adapter.
Generally, if 4 or more items change (7 or more in SP1?) it's like
tilting the pinball machine. AFAIK, the monitored items are:
Processor type
Processor serial number [*1]
RAM range [*2]
IDE controllers, which are usually part of motherboard
SCSI, if present
First detected optical ("CD") drive [*1]
First detected HD
First detected HD volume serial number [*3]
Network adapter [*1]
Display adapter [*1]
Notes:
[*1] These can change even if the hardware does not, e.g. CMOS
settings that hide or reveal processor serial number, firmware
upgrades for CD writers or SVGA cards, EPROM-level changes to LAN
cards such as forcing a type of cabling etc.
[*2] AFAIK this is granular enough not to throw a fit if you change
your RAM allocation to built-in SVGA or make other CMOS changes.
[*3] This is not a hardware item - any time you format or convert to
NTFS, the volume serial number changes and you lose that life.
Chances are while you were swapping or adding HDs, you ran for a while
with no CD drive (one life lost), ran without your original HD in
place (second life lost) and formatted the HD (third life lost). So
you'd be one nudge from death, as long as that nudge didn't happen
over three months ago; after three months of "good behaviour" (no
hardware changes) your record is wiped clean again.
Malware can pricipitate this crisis if it kills your WPA data, and if
it were to spoof your "activation" to thier site... so I'd use the
telephone number offered by the activation dialog instead of doing
this via the Internet. Yes, I'm paranoid
Finally, don't confuse activation (obligatory, anonymous) with
registration (voluntary, privacy implications) and don't feel
pressurised to register if you don't want to.
The MS activation help line folks will have seen this problem often,
and should be quite helpful. In my own experience (building and
activating new PCs regularly) they don't push you into registering;
although your context is different, MS policy is to "be
