I had 2 different Brother Ink Jet Printers that had plenty of cartridges, but the GoodWill had stored them for some time, did the Brother Clean Method. but still had lots of “crud” worthless, so nothing to lose. found a pipeete - several old clean grease rags, removed the cartridges, placed the grease rags under the opening, and into where the cartridges went. with pipette forced/skirted alcohol into openings, all four, and flushed out, this also will help clean the head area. after 4 time flushing. cleaned mess, inserted the Cartridges back, did the clean and check replacement cartridges, ea succession of test was better. did the remove and pippette alochol again, 3 times, this time on insert cartridges, and test, it was almost perfect…. any way good enough the GoodWill was able to Sell for a nice profit… I did my work FREE.
If your computer mobo supports x64 - your manual will tell you. easy to read that info. If your manufacture tells you OS is not supported, it might simply mean they DO NOT SUPPORT. I find many many Windows XP systems will run Windows 10 , so make sure your manufacture tells you NOT SUPPORT by them, the only true test is Insert the media and boot to. if the BIOS you are currently using supports the UPGRADE it normally will work.... so 1. always upgrade to the latest BIOS supported by your MOBO... 2. you should TEST the new OS by insert the MEDIA (DVD or USB) and run SETUP. if will either install or stop and tell you Not Supported. 3. Every x64 System will run x86 OS but not ever x86 can run x64. READ THE MANUAL.
Recovery Partition is easy to delete or format and when you make the Recovery Disk/USB you also rec a notice this portion is not longer available for use and recommends you click yes to delete it... most of a 1 time use. so recovery the space. This does not removed the auto recovery back to via Hotkeys... Highly recommend you read the USER Manual. on how to make your Recovery Disk/USB. and if your using Windows 8 or higher, any version of Recovery for will work. This has been tested on HP, Dell and Acers. The key is in the Bios, so it properly selects the version of OS and installs it... several manufactures have added small minor changes to "How to Restore via Recovery Disk/USB."
