Windows 7 Invalid MS-DOS Function
Nov 12, 2010
I am trying to install a copy of Windows 7 Professional x64, obtained through my university's MSDNAA program, on my desktop. Through research, and another thread on this forum i have attempted to make a USB disk to load the .iso onto the desktop, however when moving the files from the iso onto the flash disk it returns the error "Invalid MS-DOS Function" when trying to copy/move the install.wim, install_Windows7 PROFESSIONAL.clg, as well as the other .clg files. What can I do to remedy this issue and get this thing to install? The computer I am attempting to do this on is my Windows 7Pro x86 laptop.

I have a Gateway FX6801-05 which originally had Wiindows Vista installed. I purchased a complete Windows 7 ultimate (not upgrade, not OEM) from eBay. I wiped the disk then installed and verified it without a hitch. Automatic updates has been working fine.Yesterday I changed some things around on my motherboard. When I booted Windows 7 Ultimate, which has been installed on my computer for several years now, it reported that my copy of Windows was invalid. Apparently the motherboard remembered the OEM Vista product number. I tried reauthorization both on the web and by phone using my new product key of Windows 7. The phone reauthorization doesn't even allow me to talk with a support person.Did I really buy an unauthorized Windows 7 ultimate, or is something weird going on here because VISTA OEM was originally installed on this computer?

So, I've recently been getting this "The Windows 7 Home premium product key is invalid for activation" I wasn't getting this the first two weeks after I re-installed my Windows 7 home premium, so I assumed everything was fine. Then, I started to get this... I don't see why the key would be invalid, it's the key that's on the bottom of my laptop, and yes before anyone asks, my windows os before was windows 7 home premium 64 bit, like the one I have installed now.

I try to input the product key and get an invalid product key error. Now the only place I have the code written is on the actual CD i have for Windows, and that is just a burnt copy. The key and OS was from my old college I went to 3 or 4 years ago and it was legit. Everything was genuine and validated fine but now I am having problems.Now is there a way to call up Microsoft and have them run my laptop hardware or something to show that this is the same laptop and same hardware i have been using for the past 4 years and have them get me an activation code?

Have a Windows 7 64bit Compaq laptop. Tried to change time and set the time zone, but nothing works. Changed to the correct time in bios, but still cannot get a time zone "installed" It says your current time zone is not regognized. Please select a valid time zone, but the change time zone button does nothing. Tried to set additional clocks but NO time zones are listed in the drop menu. Also can't change date and time option the "ok" button is grayed out. Any help would be fantastic.

After a full installation a few weeks ago, I forgot to see if updates installed correctly. As you can see from the screenshot, there's a number which haven't installed.

I recently took my internal hard drive and bought a casing for it and made it external. But when i connected it to my computer the disk management showed it as invalid dynamic. So i went online, read a bit about basic and dynamic and ways to convert the latter into former. I adopted the method of converting through changing "hex" using "HxD". Now when i changed the '47's to '07' , i got back my three partitions without any data loss one of which was system reserve. I do not know how to get the rest back. cannot loose the data. I have to get the other three back. Total no of partition =6 (including system reserve) No. of partitions recovered = 3 (including system reserve) No

I had a dual boot with Windows 7 and Win8. I wanted to remove Win8 cause I was bored and didn't need it. I did everything right.
Dual Boot - Delete OS
But the boot manager failed. When I restarted I got an error saying that their is some invalid information. I didn't have the Win 7 disc, so I put the Win 8 disc and installed it in the partition that had win 8 before, hoping that it would recognized Win 7. But hasn't. So now I have a partition of Win 7 but it is not getting recognized.

I have a PC with windows vista installed. I recently bought windows 7 home premium and installed a fresh copy of it. Every time I download some software like Chrome, VLC, iTunes , it downloads fine, but when it has to install it gives strange errors. I have seen all kinds of errors.
E.g.: VLC gives NSIS error.
Microsoft Security Essentials gives "File Corrupt Error".
Got certificate invalid error for some other software. if I download zip files, they fail with CRC check.
Just to be sure it wasn't hardware issue, I installed vista as a second OS and that works fine. I am really uncertain what is causing the issue (seems network related though). I had an old router and just purchased a new linksys router. Other configurations are: Core 2 Quad, EVGA SLI ready motherboard, 4GB DDR2 ram, ASUS EN210 gphx card.

I put this on the wrong forum, so here it is on the correct one. Lately the Del Desktop PC with Windows 7 64 bit refuses to come out of sleep when it has been left for a period of hours. When I manually send it to sleep it does so and the mouse and keyboard are set to revive it. It revives as it should do if I move the mouse or hit a key. However whenever I leave it asleep for a long period such as several hours, it refuses to awake and I have to force a reboot with the power button. That produces the black screen which you get after a crash.

I noticed that on Win 7 a process called consent.exe runs when i try to install any application. From the consent.exe description i understood that it is the consent UI for administrative apps and i believe it is related to the UAC since when UAC is disabled, this process does not run. Does anyone know what this exe exactly do in the background? I mean what checks does it perform? Does it connect to the internet to validate something? I have a 1.8 GB setup and it takes almost 2 mins for it to reach the UAC screen when i start installing it.

I have a Dell Studio laptop which has 4GB ram and a core 2 duo processor with a Windows 7 OS.. The problem with this laptop is that, I am not able to drag and drop icons on the desktop nor in the folders... Drag and Drop never functions.. I feel convinient using Drag and drop and now this is a big nuisance for me as I am not able to freely move my desktop icons nor drag and drop the files into folders as and when required.. I also unchecked the auto arrange Desktop in the context menu.. I tried in Safe Mode.. I used a bunch of Registry cleaners, C Cleaners and what not everything.. But I am not able to solve this problem.. Can you please let me know how I should solve this problem...
Also I also have another problem during the Startup of my computer.Once I start my computer and once all Icons and taskbar come, I try to open any application or any program like IE or Firefox and when I open it, the windows freezes and says not responding.I try opening "Task Manager " from the Task Bar and and even right click does'nt function.I feel as if everything freezes up and so I need to hit "Alt+Ctlrl+Del" for opening Taskmanager.. This sounds very wierd for me as I have to do this same operation every time..My configuration is above mentioned and I also share this little info with you.My hard Disk memory usage is about 268Gb of 280Gb with a single partiotion.

As I'm sure many of you already know, older Windows versions 95/98/XP had a way of soft-rebooting Windows; it essentially allowed you to reboot the system without actually turning the machine off.
In the older versions, I believe you just held the shift button down after clicking Restart until it rebooted back to desktop without turning the mechanical parts off completely.
Does Win7 have a function like this? Or does there exist at least some kind of workaround for all the reboots required during software install/Uninstall?

Would like to disable this key combo while in games full screen mode. I know this has been an issue for a number of years now, and I'm very surprised that windows hasn't addressed it with some kind of built-in setting option, but I will certainly accept any functioning workaround.

I have windows xp pro x86, I just installed windows 7 ultimite x64 as a dual boot on the same partition.
Windows 7 works great.
when I boot up, if i choose xp, error says
"windows will not start because system32/ntoskrnl.exe"
"invalid boot.ini"
"windows could not starte because the following file is missing or invalid windows root system32 ntoskrnl.exe
I did some reading and some places say to put in my xp disk, start up with r for recovery and type bootcfg /list bootcfg/ rebuild
Although I am scared of messing up the windows 7
Someone else told me just to put my winxp disc in and do a repair..
