0Windows 7 Autologon

A very quick tip for how to enable auto­lo­gon for Win­dows 7. Press the win­dows-key and R to open the run menu (don’t use the search/run bar at the bot­tom of the start menu) and type con­trol userpasswords2 and press enter. Untick “Users must enter a user name and pass­word to use this com­puter”

I recently had to get inside an old-ish Asus A2500 laptop to invest­ig­ate an issue with the CD-ROM drive (and to upgrade the memory and add a wire­less card). Most laptops have a cov­er above the key­board that pops off, but on this par­tic­u­lar laptop it did­n’t seem attached in the usu­al way.

0Microsoft Security Essentials LogoMicrosoft AntiVirus updated

Microsoft have now updated their free anti-vir­us to ver­sion 1.0.1500 which is avail­able from win­dows update if you have the pre­vi­ous ver­sion installed (see my pre­vi­ous post). If you want to install 1.0.1500 without installing the old ver­sion first it can be down­loaded from Microsoft. If you’re in a coun­try where its unavail­able then you can down­load it from Soft­Pe­dia

0Ultrabook logo laptop vaio sonyRepair HP Laptops and other hardware cheaply

I was recently asked to look at the touch­pad on a HP Pavil­ion DV2000 laptop which had a faulty left but­ton. Spares and repairs for laptops are often hard to come by so I was pleased to find the HP Ser­vice manu­al as a PDF, which included all the part num­bers, and then very pleased to find that HP offer an extens­ive dir­ect sales ser­vice for most parts via the HP PartSurfer. Suf­fice to say this laptop is now fixed, for a very low price. Good move by HP — I won­der if oth­er major man­u­fac­tur­ers provide a sim­il­ar ser­vice?

0Google Earth LogoGoogle Earth: How to fix poor quality overlays

I’ve recently had some prob­lems with dis­play­ing large over­lays (gen­er­ated from NASA SRTM data) in Google Earth. Although the over­lay data I expor­ted was very detailed google earth was dis­play­ing a blurry mess which was imprac­tic­al for my inten­ded pur­pose. Search­ing around on the ‘net did­n’t reveal any­thing use­ful so as a last resort I tried switch­ing from “Dir­ect X” to “Open GL” mode (under tools: options).

0NoScript logoImprove your browsing security without crippling lots of sites

I always recom­mend that people install an altern­at­ive browser to Inter­net Explorer. Per­son­ally I prefer Fire­fox to the oth­er altern­at­ives (Chrome, Opera, Safari) as I find the huge num­ber of addons on offer give it an unas­sail­able advant­age. I’ve recently exper­i­mented with the NoScript addon, which enhances secur­ity by block­ing act­ive objects and scripts unless expli­citly approved. How­ever I found that I was forever hav­ing to grant per­mis­sion to every site I vis­ited for it to work cor­rectly.

0Serial Key LogoReplacing an invalid Win XP key with a genuine key

If you’ve ever been asked to fix a PC and have sub­sequently dis­covered it has a non-genu­ine or inap­pro­pri­ate Win­dows XP key installed, and you wish to update the key with a legit­im­ate key, for example when a second hand laptop has been installed with a cor­por­ate key and needs updat­ing with the OEM key from the stick­er still attached to it, you may have run into prob­lems switch­ing between OEM, Volume and Retail ver­sions of win­dows.

0Microsoft Security Essentials LogoFree Anti-Virus from Microsoft

Microsoft have released (a few weeks ago) a free Beta of their new Anti-Vir­us / Secur­ity product Microsoft Secur­ity Essen­tials. Unfor­tu­nately as a UK res­id­ent when I vis­it the offi­cial Microsoft page I am told “This beta is avail­able only to cus­tom­ers in the United States, Israel, China and Brazil”. A quick google search quickly turns up a down­load link on Soft­Pe­dia which works. There are down­loads of x86 and x64 ver­sions of Secur­ity Essen­tials for Win­dows XP, Vista and 7
