comment Possible malware modification of Windows registry entry
The value is also 256 bytes long on my machine (Vista SP2 x86) so you may be right that this is normal. Carelessness on Microsoft's part, I'd guess.

comment Are there rules to Windows 7 Environment variable names?
Not a duplicate of superuser.com/questions/27826/… ; in this case, whether it works or not depends on the name of the environment variable in question.

comment Doesn't metadata occupy any size?
For completeness, note that in addition to the information added to the MFT, there is also information added to the directory entry. (As with the MFT, however, most of the time the space for this will already be reserved.)

comment jenkins/hudson: batch CMD windows are not visible when slave runs as windows service
For future reference, in Windows 7 and later the Interactive Services Detection service (UI0detect) is not configured to run by default. If you need it, you can start the service manually, or change the configuration so that it starts automatically.

comment How do I force Windows to check for updates?
Vista/Win7: Open the Start Menu, type cmd and press control-shift-ENTER instead of just ENTER. On Windows 8 I think the Windows-X shortcut key brings up a menu that includes an administrative command line. Or on either system you can find cmd.exe via Explorer, right-click and select Run As Administrator.

@daviesgeek: 0x80240044 is WU_E_PER_MACHINE_UPDATE_ACCESS_DENIED i.e., you need to be running the script with elevated permissions.

comment How to bind old user's SID to new user to remain NTFS file ownership and permissions after freshly reinstall of Windows?
@trusktr: the ownership won't be a problem in that case, but the user profile contains stuff (most notably the user's registry hive) that can't be migrated that way. Robocopy will be fine as far as permissions go, but I recommend copying each individual folder (e.g., Documents, Desktop, etc.) rather than the entire <username> folder. Leave out the hidden folders like AppData - make sure you keep a copy, but don't copy them over top of the new account.

comment What is the difference between the number of cores and the number of logical processors?
Regarding your final question: in most cases, you'd want 16 processes to maximize efficiency. For memory-intensive operations such as image processing, I'm not sure: I recommend you do some benchmarking and find out what works best for you. You may find that you get the best performance if you disable HyperThreading altogether (it is usually possible to do this via the BIOS settings).

comment What is the difference between the number of cores and the number of logical processors?
Note that not all CPUs support HyperThreading and it may also be disabled by the motherboard (this is typically a BIOS option). If HyperThreading is not supported or is disabled, there is only one logical processor per core.

comment How to bind old user's SID to new user to remain NTFS file ownership and permissions after freshly reinstall of Windows?
@trusktr: depends what you mean; the ownership of the files are assigned to the admin user who is doing the copy, but the permissions are inherited from the parent folder. Typically, only the permissions matter.
