Ditto.  I have received several calls, and at first answered some general questions - "Is your Windows computer running more slowly, lately?" or similar.  I never gave any personal or pertinent info.  

After hearing the person's questions and noting that he dodged some info while proclaiming that he was with Microsoft, I called Redmond, Washington (if I remember correctly - the Microsoft HQ in Washington State) and learned that this is a scam.  

I have put the callers off while reporting the the phone number to Federal authorities.  They played the pointing game - Secret Service told me to call FBI, FBI said it was a Secret Service task.  Things are getting more and more sloppy with law enforcement, unfortunately - funding cutbacks, too much crime, crooks being let out of jails and prisons due to overcrowding (at least in my beleaguered state).

The man (with a heavy Indian accent) called me today, in fact, and I finally told him to quit bothering me, that I had alerted SS and FBI to his apparent scam, and he said, "So what you able to do?"  I said that I am hoping that the officers will serve a search warrant on him and raid and arrest the perpetrators.  He said, "You are not able to do.  Have a nice day.  Good-bye."  Time of call completed: 11-29-2012 1420hrs PST

I would guess that this is a forwarded number from India and our Feds are either powerless, or are being blocked by higher authorities, from doing anything at all.  That's life.  Be careful out there.

Below is a copy n paste from another forum explaining the scam:-

I get these phone calls about one a week. Last time, I was ready for them: I had a machine set up with a clean XP installation, so I played dumb to see what they would do.

They pose as "Windows Support Centre", or suchlike, and say that they've been receiving reports from your computer that there's a problem. You'll probably be asked how old the machine is - however old it is, seemingly, you'll be told that the warranty on your Windows software has expired, or that you should have taken one out when you bought it. Then, you'll be talked though opening something called the Event Viewer, and shown a screen that contains a number of warnings and errors. They will tell you that this is serious, even to the extent that it's causing problems that might force your ISP to cut your connection and/or inform the police.

Let's stop here and make two points:

1. There may well be something called a "Windows warranty". However, I have been a Microsoft Partner for nearly a decade, and I've never heard of such a thing. I think we can assume that if such a thing existed, Microsoft would be sending me lots of information on how I can make money selling it. They haven't, because there isn't.

2. I've never seen an Event Viewer that didn't have warnings and errors, and I've been a Microsoft Certified Systems Engineer since 1999. Its function is to keep a record of everything that happens to the operating system so that people like me can find out what's happening if something has gone wrong. Most of the time, though, there's nothing to be alarmed about - in my case, most of the warnings were due to a printer not being found on the network because I'd switched it off.

OK, so the next stage is that you get passed to the "Technical Department". This is where it got interesting: I was told that a six digit support number was being generated so that my problem could be resolved, and I was directed to a website called logmein123, where I could enter this number. Now, this is a common tool used by people like me to fix machines over the network - clients call me with a problem, I can connect to the machine and show them what to do without having to leave my office. In this case, they were going to "fix" my machine. So I let them in. At this point, we will pause for a warning:

WARNING: DO NOT TRY THIS AT HOME ON YOUR MACHINE. I WAS GIVING THIS GUY COMPLETE ACCESS TO MY COMPUTER. HE COULD DO ANYTHING HE LIKED, TRANSFER FILES TO INSPECT AT LEISURE, ETC. I WAS USING A MACHINE WITH NOTHING ON IT BUT THE OPERATING SYSTEM. REPEAT: DO NOT LET ANYONE YOU DO NOT KNOW AND TRUST ONTO YOUR SYSTEM IN THIS WAY.

The first thing was that as soon as he connected, I could see the IP address he was connecting from, and I was able to trace this back to a company name, and trace the company back to its offices in Mumbai. While I was doing this (on another machine), I was watching a rather nasty piece of software being uploaded to my machine and installed. A bit of fiddling around, and I was asked to try running a few programs. Lo and behold, they all crashed with frightening looking error messages - remember, this was a machine that was working perfectly a few minutes before. This was explained as a consequence of the problems that I was having before, and that the diagnostic program they were running was now blocking programs that could get me into trouble.

This was the point at which I was asked for money - they started at £100 to fix the problem I already had, with an additional £80 for a simple one year warranty to protect me in the future, or if I preferred, I could give them £299 for an all-in package including fix, anti-virus software and a five year warranty. Visa and Mastercard accepted. If I didn't want to go ahead, then I wouldn't be able to do anything with it until it was fixed.

At this point I let him know what I was doing, complete with telling him the name and address of the company he was working for. I expected him to hang up on me, but he decided to argue with me, at one point telling me that I wasn't an MCSE and I didn't know what I was talking about. In the end, I just told him that if he had been in this country, he could expect to be arrested, and hung up on him.

So, in summary, I wasted my time in this way so you don't have to. If these pirates call you, don't say a word. Just put the phone down.

LOL got the same call today, on my house phone which I basically do not give out. Indian guy that said he was from Microsoft tech support, and needed to check on my computer, I could hardly understand. him, and to get a call from Microsoft?? Sure..... I said ( I do have  Win. 7 on one.)  I asked for his "Microsoft" ID, so he said MD01E0S, which is not their type of ID code at all.
Then asked him what the name of the virus was, "TROZAN", lol, that's his spelling....

what will people come up with next?

I think this was more than a prank call...probably wanted personal info. too...

JUST GOT A CALL FROM A GUY SAYING HE WAS FROM WINDOWS, TO GO TO THE COMPUTER AND FOLLOW HIS INSTRUCTIONS, I SAID "NO WAY JOSE", I DIDN'T RECEIVE ANYTHING FROM WINDOWS SAYING THERE WAS A PROBLEM. BE CAREFUL OUT THERE.............

Receved the same call from the same person.  This is the 2nd time!  A few months ago I told him I didn't have a computer and he was shocked and hung up.  This time I asked for his number and he told me it was  (315) 633-4411.  The caller ID shows the number as (206) 701-7392.

Bottom-feeding Scumbags pretending to be Microsoft Support asking for access to your computer. They are criminals in the making. They are some of the worse kind of persons who prey on other persons. They are, as Diane said on Cheers, "Pond Scum."

Looking for owner info.

I received 2 calls from the same number at 12:15 p.m. this afternoon... 2nd call I said (again) you have reached a number on the do not call list. I am reporting it to the do not call list, and to the fbi... the guy hung up super fast!

The first time they called me (a couple of months ago) I almost fell for the spiel, but I had a friend call me during the phone call, I mentioned the call that was "waiting" he said it is a scam - so I hung up.  Today I received another call, this time I hung up right away!  The funny thing however, I have been having trouble with my computer lately - getting hit with Trojans, Virus' etc.  makes you wonder if these cyber space pirates are behind it - and then call to sell you some program or worse?

Got a call this a.m. from a man w/indian-pakistani accent saying he was from microsoft, and that my computer was sending him messages.. I told him it sas impossible, as it was not on... and he back peddled to say it was over the last several weeks... I then told him that I am onthe do not call list, and the call was being reported...

Ditto.  Some indian guy who claimed his name was Mitt Anderson.  Such bulls%!t Went along and then told him I'm going to call the police.  Idiots.

I just got the same call--same indian guy who tried to identify me and my phone number.  I didn't tell him the number naturally.. watch out for sure

Ditto ... Very nice, friendly gentleman with Indian accent advises me that my computer is infected with virus and that he will provide me with instructions on how to resolve.  He advises he can see my computer through the internet. When I asked where he was from, he advised Windows Support.  Too fishy for words, so I told him I would think about it & called back the # to see where it is coming from.  I got salesforce, but I presume he is somehow using their number as a mask...  Surely, it is some type of phishing exercise.

Just received a call from this number and received the same information.  My computer is infected with a virus...my computer told Windows...really?  I hung up on him and will report this to Windows Tech Support.

I recieved this call today, he said I was running Windows 7. I have macs but went along and he hung up after I kept confusing him.

i've had several calls from this number.  I no longer pick up.  I did get the Indian telling me I had a virus and as I engaged him in conversation he finally gave up and hung up.

Same call needed to access my computer to clean virus infecting their server, told him to get a virus program and stick it up his as*

Just received a phone call from this number...  The Indian guy claims he is calling from Microsoft Technical Department and wants to help with my PC virus problem.  After I asked him about the details of how he got the phone number and how he can help me... He finally gave up by telling me he will send a technician to my house to help me...   That's definitely not what Microsoft would do... ha ha...
