64 bit - Can I use a Windows 7 Professional 32-Bit OEM licence to install the 64-Bit version, too?

When installing Windows 7 or Vista, does the language, version, architecture (64-bit or 32-bit) or source (OEM, retail, or MSDN) matter?



I plan to buy a Notebook that does come with an OEM version of Windows 7 Professional 32-Bit installed.


Is it possible to use this licence to install the 64-Bit version of Windows 7 Professional (assuming I can get a recovery DVD for the 64-Bit version from somewhere)?



Answer



Officially and technically from Microsoft - Yes.


From your OEM - Unknown - you will have to ask them.


When you buy an OEM edition of Windows, you are mainly buying the key and not the media.... I buy loads and very rarely ever touch the CD, I usually only stick the sticker on the case and then use my PXE server to install the OS, I then give the media to the client.


The licence says the edition e.g. Windows Vista Ultimate, but it does not say x86 or x64, and the licence is valid on both editions. As like all commodities, the x86 and x64 disks are bought and sold by distributors at different times according to stock levels which means sometimes there are big price differences, I asked Microsoft about this and was told I can just buy the cheapest and use which ever platform I need as long as it is the correct edition.


That being said, I am still only able to give my clients the original disk I bought - if they require a reinstall, I usually come out to them and do it from my own disks... I have no idea if large OEMs will even help you do this.


Again, technically and legally, you can... If the OEM will let you is up to them. This is assuming you are getting an OEM copy from a big company such as Dell, HP etc. If you are going to a small company such as mine who buys their OEM disks from distribution, you can just use any other standard OEM copy and use your key.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

ubuntu - Why does my USB hdd returns SG_IO: bad/missing sense data?

I am able to boot and run commands from external USB hdd; the message in question appears for about 45 seconds then booting continues. GRUB2 is installed on internal HDD. When choosing to boot directly to /dev/sdb the message doesn't appear, however boot time is about the same as booting to internal HDD. /dev/sdb: Timing cached reads: 1018 MB in 2.00 seconds = 508.97 MB/sec Timing buffered disk reads: 80 MB in 3.03 seconds = 26.37 MB/sec pfeiffep@de:~$ sudo hdparm -i /dev/sdb /dev/sdb: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 10 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 HDIO_GET_IDENTITY failed: Invalid argument Gparted correctly identifies the drive as SAMSUNG MP0402H.

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
