Clean up the Windows.old file

When we re-installed the computer system, the new system puts the previous Windows installation files into a folder named Windows.old, which allows us to access previous Windows installation data. Usually the files here we are not used, and occupy a considerable amount of disk space, but the direct manual removal of many system files we do not have that permission to delete. Let's take a look at exactly how to delete it.

Open "My Computer", right click on the local C drive, select "Properties", open the C Drive Properties dialog box, under the General tab, click "Disk Cleanup", for example,

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/85/9B/ Wkiol1ep4pabcxuqaaf529skrci247.png "" 812 "height=" 472 "/>

The system accountant calculates how much space the C disk can free, patiently waiting for a while,

Select "Clean System Files",

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/85/9C/ Wkiol1ep4pjjuj-naaex3q8w7e8801.png "" 378 "height=" 482 "/>

Be patient for a while,

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/85/9C/ Wkiol1ep4pnbf1g0aab2lagennc899.png "" 381 "height=" 177 "/>

Tick "Previous Windows installation",

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/85/9C/ Wkiom1ep4pqglqkqaaffdiicvj4563.png "" 406 "height=" 562 "/>

Prompt for permanent deletion, select "Delete File", for example,

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/85/9C/ Wkiom1ep4prrkzauaaba4zr6org563.png "" 346 "height=" 138 "/>

After a while you can see that it has freed up more than 10 g of space, such as,

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/85/9C/ Wkiol1ep4pvd0swbaadfiy6zjpi101.png "" 485 "height=" 376 "/>

The Windows.old folder also disappeared, for example,

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/85/9C/ Wkiom1ep4pzqwcicaadg5mn3mjk608.png "" 485 "height=" 303 "/>

Thank you!
