How to clear the cache on your Windows 11 PC (and why it makes such a big difference)

Kerry Wan/ZDNET If your computer desktop looks a little chaotic and you're noticing some performance slowdown, it might be time to do a cleanup. The best way to keep things running smoothly is to ensure you're running the most updated version of Windows (you'd be surprised how many folks' devices are several updates behind). But if you're up-to-date, there are other things you can do to optimize. Also: 'End of 10' offers hope and support to Windows 10 users who can't upgrade their PCs Windows

Windows 10 EOL

Blog Windows 10 EOL June 17th, 2025 (permalink) So Microsoft decided to produce tons of e-waste for no obvious reason. There's a lot of capable hardware out there, and it would be of software company's interest to support as much hardware as possible. Instead, they made some arbitrary reason to deprecate "old" hardware. At the same time they also turned all of windows VR headsets into garbage. We'll have to wait for the open source implementations to catch up for any hope of them being usable

Try This Free Version of Microsoft Office That Runs in Your Browser

I don't use Microsoft Office very often. I do most of my writing in Obsidian and my number crunching in Google Sheets. Every once in a while, though, someone who does use Office sends me a Word document or an Excel spreadsheet. What do I do if I want to open it, make edits, and send it back? In this situation, it's probably excessive to purchase Microsoft Office. A one-time purchase of the Microsoft Office suite costs $150, which is a lot for the occasional file. An alternative is Microsoft 36

Show HN: Zeekstd – Rust Implementation of the ZSTD Seekable Format

Zeekstd A Rust implementation of the Zstandard Seekable Format. The seekable format splits compressed data into a series of independent "frames", each compressed individually, so that decompression of a section in the middle of an archive only requires zstd to decompress at most a frame's worth of extra data, instead of the entire archive. Zeekstd makes additions to the seekable format by implementing an updated version of the specification, however, it is fully compatible with the initial ve

The SanDisk Ultra-Fast 2TB SSD Is Flying Off Shelves, Amazon Dropped Its Price (Again) to a New Low

If you’ve ever had to wait for the ancient speed of an old hard disk drive (HDD) to transfer large files, you know firsthand how infuriating it is. Now that files are becoming larger and workflows need faster transfers, a solid state drive (SSD) is no longer a luxury: it’s a must-have. The SanDisk 2TB SSD is one of them and Amazon just dropped the price to $144 from its list price of $210 (32% off) which is an all-time low for a drive that’s an absolute bestseller.

Instagram May Soon Let You Rearrange Your Grid. What to Know

If you like to keep your Instagram profile as more of a personal photo album and less of a public bulletin board, Instagram's upcoming feature is for you. Instagram will let users quietly post to your profile without broadcasting it to your followers, the company said on Thursday. Instagram also said it would let you rearrange your profile grid. It's not clear how either feature will work yet. Static posts and Reels have historically appeared in chronological order on Instagram, so this could o

48TB of Your Own Personal Cloud Storage for Under $300, Amazon’s Best-Seller Hits a New Low

Oppo’s new foldable can remote control a Mac

Today Oppo launched the Find N5, the thinnest book-style foldable phone yet, but there’s more to the phone than a slim design: it’s capable of connecting to a Mac for file transfers and even remote control. It’s not quite the first Android phone to do so, but it is the only one you can buy outside of China. To link the Find N5 with a Mac you first have to install Oppo’s O Plus Connect app on the Mac, which will be available from Oppo’s website — I’ve been testing out a beta version. Linking the
