My PC works withs Windows 10, regularly updated and Miktex 2.9 for years. Today, i've run the Package Udpate manager (As Admin) tha tended normally. Since that operation, I've now a lot of problems. Latex documents can't be compiled successfully with TexMaker due to old or deprecated packages. I'cannot launch Miktex Settings and Miktex Update. The related window doesnt come and I'va a windows error telling copystart.exe and mpm_mfc.exe are not found. As I'm not realy a geek, I'ask for assistance to fix my installation after this malicious update. Regards Pierre
