text: Windows7-Mania.jp was a domain used by Microsoft Japan in order to promote Windows, notably with their OS-tans.
  They abandoned the domain at some point, then several squatters caught it, before I bought it myself from Seo.domains (I can recommend them, they have very interesting expired domains at reasonable prices for your business or Seo if you are looking for that).
  Here is the latest known archive of this root page: https://web.archive.org/web/20120905170039/http://www.windows7-mania.jp/
  I am Pttn, an avid OS-tan fan! I collect almost everything related to these anime girls, so having this historical domain in my collection is super neat! I will add some more content here later...
  Useful links about OS-tans
  If you landed on this page, you are likely a fan of OS-tan too, or at least you are interested in them! You probably arrived here by clicking on a link from an old article or so while looking for info about OS-tans. So here are some useful links about them. I also plan to compile someday all my knowledge about the OS-tans somewhere.
  General links
  The Wikipedia's OS-tan entry;
  The OS-tans.moe Wiki;
  The OS-tan Collections Wiki.
  For collectors
  The My Figure Collection site is very useful to browse existing figures and some other merchandise about earlier OS-tans, though it is not really useful if you collect the Madobes;
  Use proxies like ZenMarket, Neokyo or Buyee to buy from Japanese markets like Yahoo Auctions or Mercari, it is much more likely to find OS-tan items there than in places like Ebay;
  I donate dumps of my OS-tan discs to Archive.org, check my account if you are interested! Avoid buying the merchandise if you are just interested in the data, let them to people that really want to own them!
  Communities
  The OS-tan Subreddit...
  ... and its official Discord Server Invite;
  The OS-tan Collections Forum.
  People
  Special thanks to BetaCollector for inspiring me to collect OS-tans via his tweets, and selling me a lot of super rare OS-tan merchandise to complete my collection!
  Michael MJD occasionally makes interesting videos about OS-tans. Many people discovered them via his channel. He also donates some dumps to Archive.org, here is his account, check it too as I don't donate things that were already uploaded.
